- How to properly install a distributor on a chevy 4.3L or 5.3l vortec engine, even if crankshaft was moved. The timing is not adjustable on these models so it is necessary to install the distributor in correct alignment.

I have been doing mechanic work for 40+ years and that is the best video on this topic I have ever seen! I think all the "thumb downs" are because this video was not what they were looking for.
Thanks for a great and thorough job on the video!!
I generally find the thumbs down counter on my videos is useful in letting me know how many idiots viewed the video. It's like.... useless but fascinating trivia
This was the best information I could have found. I felt nervous starting this project, but now I feel confident!
If you have a 95 4.3L S-10 or Blazer with a "W" vin (8th digit) with CMFI (central multi-port fuel injection) the timing is adjustable. But first you have to disconnect the Ignition Control system wire (tan with black stripe) located under the passenger side dash first. Usually taped to the harness going to the computer. Then set timing with a light and reconnect wire when done. But these have 2 timing marks that are 90 degrees apart. So rotate till you see the second mark . The first mark will line up with another mark located lower on the timing cover. There is one mark on the timing tab, this is base timing of 0 degrees. Once you reconnect the IC wire the computer will take over and adjust it. A claw foot on an extension is the best way to reach the hold down nut on the distributor. LOVE the videos!!!

Great video, my buddy bought a new distributor and put it in hisself and got it out of time, I watched the video whilst re-installing new distributor and worked like a charm......thanks, keep up the good work
Ya guy don’t no what he’s doing it’s cyl 4 to set tdc and ya 45 def install hate this shit I’m lucky I pulled the manual
Not only is this a good video, your heart is in what you do and you can feel it. What is so interesting is the Tonka toy like simplicity of the design. It ain't so simple with other distributors, and I know that from experience. The oil pump slot would get to me. The explanation of orientation is absolutely the most efficient and intuitive aspect of this video. You did a splendid job.
Thank you so much!
the info about the dizzy cap i never knew thank u very much sir hoping to get my yukon back up now with ur video
Thank you for the detailed video. You made my first distributor replacement easy. I had no problems and my truck is running much better now.
I graduated from Wyoming Tech some years back.Very good explanation. I just happen to be going in with a vortec and need to install that distributor after replacing crank. Thank you for this vid, saved me a pain, very well explained and put together.
Thank you for posting, I've been trying to set the timing on my Express and this is the only clear, concise video on here.
Joshua Curiale It is one of my first videos and still my most popular. You would think with a common engine as this, there would many videos on this subject. Glad it helped.
GREAT EXPLANATION! I CAN NOW TACKLE THE WORK MYSELF! THANKS ALOT!
Thanks for the video. It solved a problem for this 67 year old mechanic. I placed the pointer where the #1 was marked on the cap and it would not start after I rebuilt the engine. Now I know why. I have built many chevy engines in times past with the old distributor but this is my first new type.
Best explanation i have found. Others dont mention the correct oil pump mark below the distributor and is the key.
Hey sir. Appreciate all that you do. Have become a better technician thanks to your teaching videos. Have some learning problems so I have no formal training. You have helped me a long way. That being said. I recently fought a vortec distributor install. As in your scenario. It was out of time when towed in to me. I spent way to much time trying to drop it in. Changed my way of thinking. You know outside the box. Brought it up to number one. Went underneath rotated to next mark on crank pulley in relation to crank sensor. Dropped distributor in at number six. Had wife bump it over until oil pump shaft lined up. Bolted everything up and done. Without your previous teaching methods. My tunnel vision would most likely have continued. Again. Thank you for what you do.
Kudos for your speaking ability and proper terminology. Right on.
Thxx v much sir
Ive looked all over youtube and ive seen multiple vids on the topic. This is by far the best explained. No shaking the camara, everythings clear. Only thing is would have been cool to see #1 piston being set to top center. Still a great vid. Ill be trying this myself when this new distributor comes in. Thanks, im subscribing.
THANKS!! Backyard mechanic that would have struggled with the oil pump shaft without your explicit directions. Bought it and had it in in one hour, 15 minutes which was lining up the shaft. Thanks again!!!
+Ostobers Even after doing over a dozen of these it still takes me quite a few tries to line it up! Matter of Trial and Error.... mostly error lol.
Great Video, helped a lot... I had to remove mine for the first time in 2008 to change the intake gaskets for leaking coolant. It took me two attempts to get it seated.

Great video, thank you Sir, you are and gentleman and a scholar.
your attention to detail is second to none, and that is needed when working with this unconventional cap/firing orientation. You made it idiot proof! Thank You!
Dude, that was an awesome video, you anticipated all of my questions including the appearance of the rotor not pointing towards the number one spark plug wire connection.
If you look at the inside of the distributor cap, you'll find that, indeed, it is pointing to #1.
I’ve been watching distributor installs on UA-cam all week. This is by far the best one for the 4.3. Thanks for good info.
This is how you do a instructional video!!!! I feel like I am watching the GMC engineer who designed this thing . Thanks.
Amen right that was pretty good wow best I've seen in a while wow
Lol
If this were a GM engineer, it wouldn't make any sense. The video does make sense though, so I know it's just a really smart guy here to help me.
I did my distributor the other night, it fired up and ran without throwing a code, this is a great resource.
I just set my distributor and it was backfiring through the exhaust. I completely forgot that fact about the vortec distributor cap. Thank you now I can get it running again.
Thank you that last part helps so much I was all what the hell. So I looked it up and found your video thank you again.

How can u swap it back to the old type
Sir, I was at the brink of desperation until I found your video and gave it "just one last try". Well, I am glad to say that I was able to finally fix this darn issue haha. Thanks a lot! Who would have thought such an old truck had such a distinct way of installing the distributor.
Thank you for a great video tutorial that helped me install my distributor which ended up helping me get 2 more years of service from my 2004 Chevy Blazer X engine code, I wish I was smart enough to follow you more regularly I believe my truck would be RUNNING WELL instead of being on blocks. I got it running but didn't correct the check engine situation. I didn't know how, cuz I have been a parts changer. I really appreciate your approach to a scientific step by step / logic process, intuitive approach. I'm learning a lot from you, but there is a lot to learn, and a few tools I'll need.
It's all about your dedication. It take me many times before I learn something!
This video is very detailed and helpful. my 99 4.3 was missing and backfiring for awhile. I put new plug wires, new cap and rotor. still no help. wasn't until I replaced the whole distributor did my problems go away! I ordered one from EBay for $44. this video made the install a breeze! if your having misfire issues I recommend replacement. take an hour of your time and do this simple repair. thanks so much! BTW, I'm no mechanic but by following this procedure it was simple! watch this a few times and good luck!!
I will say, that my new distributor did not have the factory line on it to align it before I installed it. so when I removed the old one, I simply used it as a pattern to make my own mark. simple idea
awesome video matt..i was lost for hours trying to put mine on time until i watched your video...very comprehensive and thourough..thank you very much
excellent video my friend, very thorough and spot on for the novice mechanic... Distributor install for dummies... thx
Thank you for this video. It saved my butt when I forgot to mark the distributor before it got moved.
Excellent Video. Thank you for showing how to perform the oil pump slot alignment to the distributor. Perfect!
no need to fight with the oil pump shaft. simply drop it in place, hold the distributor down with your hand, or loosely install the hold down bolt. then turn the engine over by hand, and eventually it will fall right into place. even with the shaft not engaged on the oil pump, the drive gear engages the cam gear enough where they rotate in harmony. you won't lose timing.
good vid
+Lynx Star Automotive (Gabe V) Sounds like a good strategy- I'll try that next chance I get
+Schrodingers Box I'm having trouble aligning oil shaft with drive shaft any suggestion to help me align
Robert Perez Do exactly as I stated in my post above. Drop the distributor in, and when it falls as far down as it will go, turn the engine over at the crank pulley, after a couple of spins, it will fall right in.
+Lynx Star Automotive (Gabe V) thx gabe I'm going t o have to do that after dropping I realized I'm off due to the fact of having code p0016 correlation of crank and can so I must be off. Also my distributor didnt come with any scribe or paint mark indicating the set back from cylinder 6 on distributor do you know what the set back is supposed to be because right now I'm just guessing and if I knew the set back I could do it the way you described above thank you for your help
I do It like this and it works
I found a way easier method to install. Once you get TDC., take a picture with your phone to see where the top of the gear then just match the distributor up with the picture. Drops right in and lines up on the number 6
This worked for me. 👍
Thanks Matt I appreciate Your knowledge and method . ✓
Anytime!
Does this work for a o7 Silverado classic è⁰
This video seriously made so much sense
Everything else online jumps around and is confusing. This walked through perfectly
Wow, Im astonished. I have a 4.3 apart for an intake gasket right now, didnt notice a thing about the dist. Watched this video for the hell of it.
My only thoughts up to this point was "I need to find my old timing light when I go back together". Thnx, great info!!!
Hey Matt. On the vortex v6, there are 13 teeth on the distributor gear. Thus, 360 degrees / 13 teeth = 27.7 degrees per tooth. If you are at TDC, any misalignment should be blatantly obvious if you are off even a single tooth.
On my 2000 Vortec v6, I am somewhere between 5 and 10 degrees off on the distributor mark while at TDC (verified absolute top on #1 with horoscope). This is the closest I can get, any other tooth alignment will be ~28 degrees away. Now, maybe I have something else going on (timing chain)?
Also, on some vehicles, it is almost impossible to line up a screwdriver head with the slot the oil pump shaft through a blind hole (abyss) in the rear of the engine, underneath hvac lines and wiring. Once you get first distributor engagement with the cam teeth, but before the oil pump shaft is aligned, you can manually turn the crank until the distributor aligns itself with the oil pump shaft - gravity will cause the distributor to set in place, then you can bolt it down.
Excellent deductions! Yes even off one tooth it is indeed blatantly obvious for the reason you stated. If you continually find it is impossible to line up when doing this correctly, I agree you may need to chaeck your crank and cam timing relationship.
Also yes, it takes "feel" to adjust the oil pump shaft- on this model you cannot see it. A strategically placed mirror can be used to help but it's tricky working with a mirror image!
My 2000 silverado vortec 6 cylinder has an o-ring on the distrubutor, but it is intended to seal the distributor housing to the engine (hole is in the Intake manifold as i recall). There is no Oring between the distributor and the cap, nor would i want one in my engine.
exactly, the drive gear is very coarse so if you're off, you'll easily see it... just pull out the distributor but first mark where the rotor is pointing first... Then just put it back in the way it was pointing. Now this doesn't check the timing, but just gets you back where it was.
Bob's Barn Workshop So I mark where the distributor rotor is pointing, pull it out and install the new one in the same orientation?
@@SchrodingersBox there was no room under my cowl for even a mirror, I ended upusing my iphone held over top so I could see the driveand then adjusted with a screwdriver inside a lenth of conduit
Very good video. What 5.3 motors are you talking about? The Vortec motors that use a distributor are the 4.3, 5.0, 5.7, and 7.4.
so is this video good for the 5.7 engine?
John Black yes it is.
Great technical video, thanks for all of the important details. I was easily able to change my distributor thanks to your instructions.
Great information that has corrected an old time mechanics error. My things have changed. Thank you for sharing.
the title is misinformation 5.3s dont have distributors only old vortecs 4.3 ,5.0 , 5.7
update: i installed my dizzy this am and shes running great so far, thanks for the video. I never had to mess with tdc, i just used my old roter with my marks,i will prob eventually get a new roter.
great video had a mis fire problem changed spider injection new ignition coil and distributor rotor and cap thanks to your videos i fixed the problem myself saved me alot of time and money. thank you.
I want to thank you for a very excellent job in explaining everything I wished everyone was as clear at explaining thanks have a great day
Another thing that can cause spark ignition issues is the cap and rotor check the cap for corrosion and arcing. This video did help me a lot the with Alignment of the ignition timing. Thank you!
The mounting tabs on mine were broken, so my cap was just sitting on there, Surprises it still ran,
I'm doing this tommorrow with a new distributor, thanks for the vid!
Great write up. It helped me organize my thoughts to reassemble the motor.
I used a compression gauge to cylinder number one along with chalk marks on harmonic balancer.
Aligning the oil pump shaft proved a little tricky for me. I couldn't get the screw driver head into the slot. So I took a piece of 1/2 inch electrical conduit about 8.5" long and dropped it over the shaft. The screw driver could pick it up real easy then.
Well she started right up after install. Idle is about 1500 and getting code P0016.
Very awesome video and explanation of this...I was in the "old school" method and tried about 6 times until fully watching this...Thanks a million!!!!!!!!
Working on a distributer like this (I have a Blazer with a 4.3) is a new experience for me. I'm used to the ones that can be adjusted. Thanks for the tips! It'll be a snap now.
I have been a mechanic for a long time.Some have it some don't.Your the real thing
You're the man brotha. I am super confident I can do this job now. Thank you
I greatly appreciate your thorough, orderly instructions. I successfully replaced the distributor in my '05 Silverado 4.3 Vortec with 97K. The symptom was intermittent spark on #4 cylinder - which was challenging to diagnose. What I found was a significantly worn gear on distributor shaft. I used a Delco OEM distributor with all necessary markings. Thank you Matt !!!!!
this is the best vortec distributor install video out there..dead on..thanks man..
Ok watched your video ( twice to make sure ) and sure enough the rotor lined up just like you're in your video. started right up !!!! You Exsplained it perfectly ..Ty Godspeed
I just got done swapping an engine on a 99 express van with the 5.0 vortec and I had to remove the distributor for clearance and I thought I marked everything I had to put it back on, but after watching this video, I think this is why the won't fire up, I get spark but it's not consistent it pauses.
I'm going to try to set the engine to TDC for cylinder 1 and install the distributor the way you showed hopefully she fires up thank your videos they are very helpful
The best description I have seen without question!
Thank's Schrodinger that's the second fix you helped me with. The first was making sense out of my O2 sensor readings.
i spent hours today trying to time a s10 after a head gasket job. untill i watched your video! good job and thank you tons!
+jon malveiro Same with me lol... its why I filmed this
i almost forgot that painted mark and the pumple relationship - thanks 👍
Deric, indeed this is exactly why I like to "start fresh" with installing the distributer at TDC every time. Even if you do mark the distributer's original position accurately AND reinstall it exactly, this assumes the distributer was in correct position to begin with (maybe not as much an issue if it's your own car, but I usually get cars from people who gave up trying on their own and who knows what they've done!!!). I hope this video helped you. I do hate inaccurate repair manuals lol!!!
Hey Matt, first off thanks for the video. I found it to be very helpful and had more information then my repair manual. so people know why their engines not starting. If your tdc on the balancer, but your not lining up on the six, your just before it or just after it that is the exhaust stroke, so just turn the crank another 360 degrees and line it up until it's lined up with the "6". 95-97 has no white line so line this up right before the screw hole before the six and your rotor will line up.
Thank you so much for posting this video, I was stuck on how to install my distributor I was searching for help on youtube but not body was very clear as you explained so clearly.
You are welcome!
Thanks bro you helped me pull through. Can't thank you enough, you are awesome. Everything worked out like a charm. Just like you showed on the video. Thanks for showing me the light. Can't thank you enough bro.
Yes it did. Thanks Much. Need to double check but I am pretty sure I got it set right. But to be sure, I'll pull my distributor, reset TDC, realign the distributor marks, and drop it back in.
Had to redo the intake gasket on my 1500 with a 4.3 Vortec.
Exactly the info I needed.
Thanks for taking the time and the vid.
Saved me some cash... i was about to call a mechanic for this. Thank you sir.
Very helpful well explained video .thank you I did it wrong the other day,wouldn't turn on but now after watching this I'll get it right
I followed the hanes book , which did not give the v notch and harmonics. I had noticed the slot in the bottom which is not mentioned and figured what u showed was what was happening with the time. thanks for the proof...
great video very informative but you did not show how to set #1 to t.d.c. but once i got that issue resolved this video was a great help thank you. im only pulling the distributor because i had low oil pressure and knew that the oil pump could not be the problem. I found that the old distributor was wearing from rubbing the intake and leaning to one side causing low oil pressure.
So glad I found this video. Working on a 99 express. May be an old video but man it’s so well explained. Thank you sire 😊
Glad it helped!
@NewECus-Thanks for the comment. I think you are right on with the timing light idea, it's a reasonable start but I'm thinking you won't find it as definitive as the distributer pointer method shown in the video. With car warmed up you should be at about 12deg at idle so make a paint mark on the timing plate there and see if you're in the ballpark. The timing is adjusted by computer. If distributer has ever been replaced, I’d reinstall it as shown first. These cars have timing chains, btw.
That was by far the best video on this. Thanks
Thank you for your kind explanation. Its cold here and you have reminded me of all the things I use to know and forgot. God Bless you
Michael (central Kansas)
Bro Mikey It is a good point- you absolutely do forget a lot of this stuff when you don't use it regularly. In fact there are a few time's I've even referred back to my own videos for refreshers lol.
Hard to believe you can find this great information for free. I was so used to the older dist caps I was setting
very informative video. I was going to take my truck to a shop for this replacement. Not necessary after watching this.
Great video Matt, I got a do a distributor on a 1998 silverado 5.7 I will do exactly as you shown in the video, thank you matt, cheers from Ontario ca.
This guy matt knows his shit.I had changed my stock Distributor with an alum. base.Distributor.This distributor is a lot harder to install compared to the Hei distributor.It took me awhile on how to changed it.But got it done.
Thank you sir for the excellent video, and special thanks to commentor Gabriel Velazquez who saved my bacon when I was fighting with the oil pump engagement. I could not see into that hole and I fought it for several hours trying to get a screwdriver in there and adjust it by feel, with no success. I then remembered a comment on here about a different approach (Gabriel V's) which I re-read, and using his method (install the distributor in the correct position and then rotate the engine manually until it seats on the oil pump) I had the new distributor correctly seated and fastened down in about 15 minutes. Cranked right up, no codes, runs great.
...my number 1 way off. Thanks to this video it was a breeze. This was my first time working on something this new. Just wanted to say thanks and keep up the good work. Your correct terminology really makes it easier.
Hey man just wanted to say thanks.. This is about the best vid I have seen that is the most correct and with the most info.. Just wanted to say thanks again.. GOOD JOB!!!!
I have watched this video, a few times, and your explanation, is the best, I have an 01, express conversion van, with a 4.3, and I have to replace, the intake manifold gasket, so I know, I will be watching it again, a few more times, thank for sharing your knowledge, I'm not looking forward to this, but it has to be done, great job, thank you!!!!!!!!
Awesome, thank you!
dude this gives away two days of my book interpretation and includes information they didn't include intentionally
Matt you're an awesome master technician man, thank you so much you're the best! Always enjoy your videos.
Thanks very much!!
Anyone that is wondering about this video, Matt is dead on with his info. If and when you use this info, follow it to the letter and when you go to start your motor it will fire and run on the first try as long as there is no other problems. Good job Matt, thank you for honest advice.
This dude knows what he`s talking about.I did everything he said.No problems at all.
This was very instructional, thanks for the content!
Thanks for the great video! Very clear and to the point. The dimple on distributor gear and mark on distributor shaft was awesome.

Matt, even after so long, this is still an outstanding video. You saved me hours of time. Thank you.
Thanks man, yeah it seems to still be the only correct video out there for this application. Amazing isnt it!
I have a 2000 Blazer 4.3L I had to to replace the intake gasket 3 years ago. I wasn't that comfortable tackling this job at home but my mechanic neighbour needed cash and said he would do it. We had the intake off so we decided to replace the original rocker cover gaskets and OEM distributor where the insert moulded screw knuckles had cracked the distributor base plate and we opted for the after market distributor with a solid metal base plate to avoid future failure. My neighbour and I messed with that distributor for a few hours reverting to TDC alignment and could not get rid of a code it was setting. We finally recruited another neighbour who worked at the local GM dealer. He got the code cleared with my Tech2 stating we had to initialize the new distributor / sensor. I guess in your video this was not applicable if you were using the same distributor but I thought it may be a helpful hint if someone was replacing their distributor. BTW: your videos are awesome.
i thankyou very much,,the factory mark on bottom and little punch mark on gear drive fix me right up,,THANKYOU VERY MUCH!! your a life saver
mike wysong Thats how we roll on this channel!
thanks, that's exactly what I needed, I saw the mark but I went to number one on the top.
Thank you just did intake manifold gasket on my mother's blazer and didn't set cylinder 1 at tdc....well you know what didn't happen. Thank you thank you thank you!
thaks for this video. I used it to fix my 1995 gmc safari. that has a problem with the distributor. very helpful.
Hey matt I was just about to make the same remark LYNX STAR made. That is in fact true. When you get the rotor aligned as you mentioned, and most savy tech know already. but yes I usually hold down the distributor while someone bumps over the ignition and as LYnx mentioned it will drop into place.
Thanks man! I was able to fix my truck with your video
Your videos are great to watch, I learn so much and I feel I understand things conceptually thanks to your videos. Great job, Thank you!
I just changed out the distributor on my '98 5.7 Vortec. I had code P1345. Searches led to me here and videos posted by "ScannerDanner". Watch both. ScannerDanner explains HOW the wear on the teeth contribute to the code being generated. He was absolutely spot on with his advice on worn gear teeth. I went cheap going to the junkyard for a used one. (I didn't know it was possible to buy the gear separately, but for $16 bucks, what did I have to lose?). Pulled one, and noted worn teeth. Pull a second one. All teeth present and/or accounted for. With a junkyard distributor in hand, I went to pull mine and I tell you, about half the teeth on mine could have been harvested for emergency zombie apocalypse razor blades. Mr Schroedinger's contribution for high praise extends to his EXPLANATION on how the distributor works and the installation thereof. The alignment on the 5.7 liter technique was just a tad off from the 6 cylinder model he was showing, but with careful attention to where the rotor points allowed me to get correct alignment on the first try. HOWEVER, the supercritical alignment of the "screwdriver-type 'blade'" on the end of the distributor to mesh with the oil pump using the screwdriver method is a little flawed IF you don't possess probably an 18" screwdriver, or longer. The added comment from Lynx Star Automotive to install the distributor 'hold down' flange and bolt with pressure, and then turn the motor over by hand, resulted in a small "thunk" while I was rotating the crankshaft giving me an audible signal that all was in alignment. I tightened everything up, reinstalled the spark plugs, inserted the key, and she started right up!. Cleared the codes and passed emissions, reducing the flunking 3828 PPM of hydrocarbons (allowable amount in WA State is 400) to 298. So $16 bucks, my time, and my satisfaction to learning a new skill at my Medicare Card age was all the satisfaction I needed. To often we forget to thank the teacher for skills that last a lifetime, so thanks Mr. Schroedinger and also Lynx Automotive for the tip that made the job relatively easy
Best chevy distributor install video, thanks!
Seems most comments are about confusion on TDC, marks aligned and #1 comp. vs. exhaust.When you pull out your dist. (if it hasn't stripped inside somewhere) just take off your cap. align the 6 to the rotor and put the new one in the same. If your wanting second confirm the marks should line up the fist balancer mark underneath to the mark on the timing cover (that's seen easily from underneath) and the second mark lining up to the mark from above (also on the timing cover, harder to see).....there are two marks and two lines on the balancer.Also..lots of reman. dist. have the dimples installed wrong, you're just going to have to play them as dealt or return for another. Matt, your vids are great for us backyard mech. I thought I'd have to give up working on cars years ago because of all the library research it involved but the interwebs and guys like you saved the day.
Ii know u got me out of my fear afew years ago when i replaced head gaskets on my 2000 chevy blazer 4.3 scared to death id never get it right myself i give u a vary vary big thums way up and bless u and a happy 2020 thanksgiving
Hahaha, man the first time i ever replaced head gaskets I had to do it 3 times before I finally figured out the head was warped. Sounds like you are on a way better track than I was!!!
@@SchrodingersBox i got rid of the blazer
My friend You are the best . Excellent I mean Excellent video, an instructions of how to properly install a distributor.
Glad you liked it!
