- This was done to a 2005 LLY 2500 HD Duramax 6.6L. Make your you order the Leslie tool before you start this project, it cuts time in half. Thanks for watching and as always please subscribe!
Thank you for the detailed wrench/nut sizing and torque specifications. Those details are typically some of the most difficult to find.
This video was a life saver! Every other video i could find didnt really go step by step they skipped through parts. Just done my lb7 tonight and couldnt have without this!
This is by far the best Instructional DIY Duramax Waterpump Replacement Video on UA-cam!! Awesome content! Thanks for explaining everything so thoroughly and not "beating around the bush!"
Truck Master has helped me keep my LB7 alive and healthy. Thank you for all of these extremely helpful videos!
Truck Master is part of the reason I still haven't sold mine
Hands down best duramax repair videos on UA-cam.
Thanks Matt
I do these pumps every now and then. I still refer to this video because it's short and sweet
Great video! Did the water pump on my LLY years ago. It now has 476 000kms. Runs and drives great!
Bro you are the man...I was quoted over $1000.00 to do my water pump, I said f#%# that and went straight to UA-cam....video was excellent, straight to the point no bullshit and unnecessary info....took me 4hrs once I had the right tools and I'm a landscaper by trade...thank you
Thanks chris
Pumps in the Mail ....gotta get a 3/4 bar still lol I’m a landscaper as well .....not looking forward to this but hey ....bring it on
@@nthewalk where did you buy from?
Man if it weren't for you and youtube I'd be so screwed! Thanks for all the detailed explanation.
Thanks man
replace the O-ring no matter how good it looks, $2 will save you a headache if it leaks when you get it back together. helpful tip.
i got it all back together and the fuckin oring was leaking. shoulda fill the coolant before proceeding any further.
Same thing happened to me I put it all together and it was leaking right there I should’ve tested it before I put everything together The o ring looked brand new but I guess it had its day never again replace even looks good
Same thing happened to me! Kept pinching the oring! Actually ruined 4 found them at Ace hardware bought everyone they had at the time😂finally caked on the white litheum grease on the oring...worked
Are you guys all talking about the O-ring on the top tube? If that’s the case I’m in the same boat 😂
There's also an o ring at the end of that pipe that runs back to the oil cooler. It may have been fine but when you're that far into it to ignore an o ring with 165k miles... It was a pia to pry out but did go back in fairly easy with silicone grease. Not sure if it's a special o ring but the dealer gets about $30 for it.
Took a little time but replaced my water pump this weekend. Thanks for your video, it helped. Saved about $600-$800 per some of the quotes I got locally.
Glad it worked out for you
I’m getting paid 800 and it’s barely worth it, the fan is a massive pain in the ass because everyone has like 400k miles fml
Thanks for the tips, this video was extremely helpful. I just replaced a water pump in a duramax powered cube van, took me 12 hours! Tight area to work even with the rad out.
Great video.Replaced the water pump yesterday. No leaks and running great. Your video saved me. Thanks
You can use a beam clamps to hold the pulley and use a 18" crescent wrench to loosen the fan, I do it all the time. Place the beam clamps at about one o'clock and tighten on pulley, Allow the beam clamps to rotate counter clockwise and touch the thermostat housing, the fan will come loose with the tap of a hammer on the handle of the crescent wrench. Same thing to tighten, just allow the beam clamp when rotating clockwise.
Followed every step in your video on my 05 d-max LT and saved a few steps by having a lift and worked out great. Thanks for the videos, helps a lot.
Nice thorough video. Very helpful. Simpler than some others I watched!
Thanks for this video, just did wp on my lml this past weekend, however, I would like to point out that the intercooler pipe removal wasn’t necessary in my case, I got the outer rear nut loose by a short socket, swivel, and long extension, the innermost nut, is easily visible and accessed from the underside, with just a ratchet and socket by reaching up between the sway bar and frame x member.
I recommend not putting the fan or shroud back on, after you're done swapping the new water pump, Fill it with coolant first and start it to check for any leaks, just incase you need to take it apart again. Once everything checks out good with no leaks put everything else back on
Sage advice right here.
I recommend putting an electric on it and never having to worry about it again lol
@@wewillsurviveone not on a duramax
i use a coolant presser pump to look for leaks before ever starting any engine that had coolant in it... and i would never add coolant only water until i was sure no leaks anywhere. that's how i roll,,, coolant is like gold now. water is cheap and easy to clean up but i am a world class Mechanic that has been wrenching forever...
@@wewillsurviveone No electric fan can flow enough CFM for the Duramax, unfortunately.
Also, I found out the hard to fill it and check for leaks before reinstalling the fan. The upper pipe was leaking from the thermostat housing, somehow the new O-ring got cut.
Such a pain.
I’ve been a subscriber for a while now but decided to go back a few years ago. EVEN THEN! QUALITY knowledge. Back in January 2020 I was dead set on powerstroke but now I want a duramax!
Awesome finally someone who knows how to do a good video great job ! Definitely rather change the waterpump on a cummins 12 minutes in a parking lot 😂
Wow! Practically have to take apart the whole thing.😢
Thanks for the tutorial.
Thank you for including the torque specs!!!
Nice job. Be aware it is dangerous to use a click-type torque wrench on aluminum. You may end up with more than one click as the aluminum cracks! This happened to me years ago before I knew better. Best to use the "needle-type" torque wrench that gradually increases torque.
+akonitony2 great tip thanks
Also need to hold your mouth just right whenever using a hammer. Curl your lip a little more. ;)
😂😂 this makes no sense. But ok
Great video..Thanks for sharing. I did review the 20
04 service manual for the LLY and under specifications gives the Harmonic Balancer bolt toque of 74 ft pds the on the first pull then turn bolt an additional 90* ( ref service manual 2 of 5 , page 6-1159 )
Oh...and slip a towel or old bedsheet in over the radiator to protect hands from cuts...and protects a little encase you drop the fan
good tip. those fins are razor sharp.
Use cardboard against rad.
I went in blind on the duramax and took me a week to finish. Had to buy a 3/4 inch breaker bar and 36mm 1/2 inch socket and had to wait for the flywheel lock to arrive in the mail. The work was easy but waiting for one part while I had all the bolts off except for the one behind the crank pulley was annoying.
Removing that fan is pretty easy if you use an Air hammer with a veritable trigger and a long blunt chisel bit in it. The vibration of the air hammer makes even the most stubborn ones just walk right off. No need to blast it with full power. Just about one third to one half throttle is plenty.
I'm glad I saw this I'm taking mine to a shop.
what did the shop hit for labor ??? thanks
@@bobh8689 I paid a total of 580.00 pump, Included. I had another quote of 1925.00 from another shop. That was a no brainer.
Watching this video was helpful thanks again TM
I've done this with out the tool and with out pulling the starter. I jammed my cheater bar under the pass. Frame rail and hit the starter.
i just bought the air chisel tool for removing the clutch fan, only $80 it is a large kit with many different adaptors in the kit so happy.... just say`n...
Great clean video man!! I appreciate you!!💪,, keep up the great work! God bless!!
Thanks
Legit going to just watch this video as I do the job 😅thanks man
I would recommend anyone doing anything with the coolant-- waterpump, hoses etc, get a refill kit. These work great-- got mine on Ebay for $40. It vacuums the system down & cks for any leaks & then you put coolant in a bucket & it sucks it back in system.
I'd say it's worth the time to pull studs on back of pump housing for pipe to oil cooler. It's only burned me once but the pipe coming out of the oil cooler by filter can be a nightmare to get back in place without leaks. A 1/4 drive E25 socket I believe gets right in there.
Going to do this today wish me luck haha doing my 04.5 lly
How'd it go?
One thing you should mention is that the harmonic balancer bolt is one time use so it should be replaced. Also the fan clutch wrench is like $20 or the one from merchant automotive is $35. Much better than the pry bar.
Soup Nazi air chisel works good too
Ok…broken 2 breaker bars trying to break loose the balancer nut. Any tips greatly appreciated. Your video is spot on w everything so far. Just can’t get past this nut. PB blaster, heat, long cheater bar all tried.
3/4 inch breaker bar will do the trick
@@TruckMaster I broke 2 1/2” breakers. You think a 3/4 will be that much stronger and do the trick?
Maybe include video reinstalling the down pipe into the top of the water pump. I'd like to see how you line everything up
Very thorough video.Thanks.
Released the tension on the belt and finally pulled off the harmonic balancer but I can’t find the key and even swept with a extended magnet . Let’s see if tomorrow morning that I can find it .
Next is the water pump, already remove the 3 front bolts , now to see about those 2 in the back .
I almost fell off of my cinder blocks .
What?!? The key is on the shaft of the balancer, not an actual key to install bud
Awesome tutorial! Straiht to the point.
Thank you for sharing your knowledge brother!
Very helpful and saved My ass got it done in about 3hrs thanks you
You're video is great thank u.. iv broke 2 1/2 inch drive breakers and a 3/4 to 1/2 adapter i have ordered a 3/4drive for my 3/4 ratchet i will try the heat thanks again
PS my elbows hurt..lol
+Hammertree masterchief good luck! 👍
The pulley really has to come off for the water pump
nice channel... currently doin my fuel injection pump install on my lly... liked water pump video did it may of this year... keep up the good work
Ashton Henderson good luck with that might as well replace those thermostats while your at it. Thanks
Ya I think I will and all fuel limes too... what did you do for prep to spray your turbo... lookin at doin same
How did you keep the seal from ripping when you put the water inlet tube back in ?
Thankyou for this video
No problem
Great instruction, thanks for help
+Anthony Micsko glad to help!
Ok , so my truck is a 2008 2500 Chevrolet Duramax and I’ve taken off the big nut and that I punched it and used a large crescent wrench .
I’ve taken off the two bolts to that oil line or radiator line on top but ya say that we shouldn’t have to remove the belt.
I don’t see how else that harmonic balancer is gonna come out with the way the serpentine belt wraps around a part of each .
It’s getting dark and I’ll have to go and buy some lights , cause now that I have to wear reading glasses it’s all blurry wo em . I used a galvanized fence pipe to my Pittsburgh 3/4” torque wrench . Got it at harbor freight cause she will do over 260 ft pnds .
Hopefully ya may see this and comment or if anyone else has replaced their water pump on 2008 Chevy Duramax 2500 6.6 . Thanks 🙏
I also already took out the intercooler pipe and that was so the fan shroud would come out.
Gonna try and pull that harmonic balancer by hand again & watching for the key .
Thanks saved me money love UA-cam
Ironically it started raining on me while I was changing mine as well 😂
Spot on! Good show!!
GRACIAS AMIGO, ME FUÉ MUY ÚTIL ESTE TUTORIAL, ME SUSCRIBO.
Thanks 👍
Did you reuse the harmonic balancer bolt? Have read a couple sites that say it can’t be reused.
Thanks again for the instructional video!
Yes I always reuse them and never had a problem
Thank you brother 👊🏽
So that tool that ya used to punch the big nut I couldn’t find it @ NAPA , Harbor Freight , O’ Reilly but I found a tool that’s 24” Jimmy Bar .
Harbor freight has em , just not close to me and @ the lowest price , even lower then Walmart .
My water pump came with instructions saying I needed to purge my coolant system, do I need to do this? If so could you please show me how? Your show is awesome, very easy to follow, you’ve helped me with several things already, thank you. I accidentally posted this same comment on the next video, sorry lol
Thanks dude great video appreciate you
Fuck buying that tool use a pipe wrench to grab it from the out side turn it till it's in a bind or have some hold back up and bust it right loose works like a charm
Thanks for making a very good video! Thank you!
Ain't doing nothing if you don't have bloody knuckles
You said in one of your other videos that replacing water pump was a 12hr job. That does not look like a 12ge job
So the pipe will push back in thanks man
Thanks very helpful 👍
something u did NOT say, is when removing and installing the balancer, be very gental with the location pin,/keyway you hit that to hard it will fall out and or be off centre, which can cause weird vibrations in the engine and possibly break the crank.
seen it before.....
My balancer did not simply slide off like it's supposed to. Had to pry very slowly from both the top and from under the truck, still barely, slowly came off. Needed replaced (had a crack) and the new one definitely did not slide on easily, either. Emory cloth on a slotted bolt spinning in a drill for a minute or so on the inside of the balancer (probably removed a half of a 0.001" and then it finally slid back on with a shot of WD. Can't be the only one who had to deal with this!
Nice video fellas, great job!
+Rick Rodriguez thanks!
Hey dude! Can this be done on an engine out of the truck, with the harmonic balancer still on? I am swapping engines on my truck and wanted to do this for preventative maintenance while it’s out. I have no flywheel or flex plate on it (my truck is manual so I pulled and sold the flex plate) so wondering if I can do this out of the truck, and without pulling the balancer.
🤟🏼keep up the amazing work I go to all your videos for any work I’m about to do I don’t even mess with other channels lol.
Thanks! Unfortunately you still have to pull the balancer
@@TruckMaster thanks for the reply man, I was taking a look wondering if I could use some kind of bent wrench to make it happen but I think your right, thanks for confirming with me. I’ve done a lot of mods to my LLY and followed all your diy videos. So thanks from BC Canada 🍻🤟🏼
On the ram belt was that 47 hammer chip pounds? O also love that o there goes the washer now don’t do that lol.
So I have oil on the back side of my harmonic balancer washer. Does that mean I have a front seal leak or something?
What is the part number on the lesly tool? Also is the a water pump you recommend buying thanks
Excellent Video
Thanks man
I got the two nuts off with out removing the inter cooler pipe or fender well
1911kaden how
Bend a 12mm wrench or ratcheting wrench
Good videos as always
This is more of a question than a comment. I'm putting a water pump on my 07 duramax. It has a gaurd type thing around the fan . Is that necessary or can I leave it off?
Keep it on
@@TruckMaster First off, merry Christmas. Thanks for the reply. I will leave it on . I have more questions about the water pump, but I don't want to bother you on Christmas, so maybe later.
@@TruckMaster So here's what I have going. I replaced my water pump with a new napa pump. The new pump is making a whining noise. Not very loud but noticeable. I assume the new pump is no good. If I'm right about that I want to replace it with something better. So my question is what pump is best.I googled it and that really just confused me because of all the different opinions. I figured you would know what I need to do. Thanks for any advice you can give me.
T-M,,, ur awesome for doing theese vids.... a good mac is hard to find
+Dave Nun thanks
I changed o-ring on the top of the crossover pipe bc other one was flat and I only found a thicker one and worried was gonna be to thick I went down size and stretched it over top pipe in hopes it would think the o-ring so to speak. I don't feel it sticking out from pushing it up in there but the bottom is not lining up with the holes at top of water pump bc it hits the top like the pipe needs to be pushed in more to thermo housing but I'm unable to get that extra 1/8 to 1/4 that I need. Could o-ring be the issue or got any tips? Yes I did lube the o-ring b4 putting it on pipe and then b4 pushing in top half
I love all your videos and always very helpful where can I purchase that Leslie tool
Thanks 👍 you can buy them online like eBay or amazon or a auto parts store
@@TruckMaster It's different for the 4500/5500 but just as easy to get.
daggom bud. thats a lot of work. at least ill know how to do this now when the time come. hey what tool did you use for thar bolt. the one where you stacked the wrench.
TrollMaster300 36mm 12 point
Next time make easier on urself and just put breaker bar up against the alternator and use bungee to hold it in place then tap ignition and it break the bolt loose with no issues. Take like 5 min
You live in Florida? Ill meet up and bring you some beer, lol. Not sure if I want to tackle this. But, great video on how to get it done.
+Sean Boyles I wish I lived in Florida I'm in Michigan thanks man good luck!
Keep it up great video? What do u think about keying the crank? I have an lbz and the water pump failed. Literally in the process of replacing. What’s your thoughts red dmax store water pump or Danville? Thanks stay blessed
I just did mine. just went in from bottom to pull nuts off back of pump. so didn't need to take inter fender wheel out or boost pipe off. my problem when doing this is the coolant pipe kept cutting oring s when reinstall ing ended up getting a thicker o ring and lube the shit out of it. so if was to do another one I would not remove that pipe. but thanks for ur videos I have watched all of them because I love duramax s
+Jason Scruggs that's a great point that O ring can be a huge headache thanks for the support man take care
I think a person should just put a brand new o-ring in at both ends of that pipe when you do water pump, and that little piece of 3/8" hose attached to it too. Would have saved me a lot of grievance. I had to pull everything apart a second time to replace all that crap.
STP oil treatment on any o ring allows them all to slip in with no damage.
I have oil coming from around that area Josh would it be the o ring on the water pump bad leaking oil down the front of my motor???
Quick question bro… I have 2012 lml Race Truck.. I have a wcfab completel delete …def delete..both up pipes along with the down pipe… 5 inch exhaust.. airdog lift pump… fleece cp3 conversion.. running a tune as well nothing crazy …engine and transmission are stock no internal work stock injectors etc… my water pump is leaking ….with all this on the truck can I still run a normal ac delco or auto merchant water pump based on the info I’ve provided ? I’m hearing if you have a performance truck with tune it can damage your water pump due to the increased horse power it has now ….. again my lml pushing out maybe close 500 hp or so … any advise would help🙏🏻
You know your shit i must say 👌
Got a leak under my 2004 lb7 duramax. Truck has 207,000 on it and was wondering if it could be the water pump. At an idle truck leaks out cooling seemingly directly under the water pump. Upper radiator hose isn't hard so I'm thinking it's not head gaskets. Get back to me thanks! Great channel!
+Tanner Campbell look up the term weeping hole, the hole is part of the water pump housing, if that hole is leaking while the truck is running your water pump needs to be replaced. From what you are saying it sounds like you have to replace that pump sorry about that good luck if you need any advice let me know
Truck Master thank you sir will do
Just found your channel and damn am I excited! What are your thoughts on TIG welding the water pump impeller to the shaft? (low and slow to keep the heat down). Have you seen any issues with just replacing it OEM without welding, or is it just hype? Thanks!
It’s always hit or miss but replace with ac delco one, I see welded ones fail just as much if not faster, only ones that hold good are the Danville ones.
@@codydicarlo4518 Thanks!!
Is that a 3/4 socket
I have a question, would a turbo that blew up cause a water pump to go bad? I’m only asking because I had a shop put in a aftermarket turbo but it failed and oil was spitting out of my exhaust and now my water pump is pouring coolant out of the weephole. The truck has never once got hot on me. It’s a LLY.
Probably a coincidence. My 2nd water pump went same time as my cp3 🤦🏻♂️🤷🏼
So I have a lmm and have a slight leak where the inner cooler tube is on the driver side I see 2 bolts connected to a black metal tube one on each corner and had a drip of coolant whipped it off and see no more with truck running . But my question is do you half to remove the hurmanic balancer on the lmm engine ? If not then I would change it myself the water pump . I see lols of people who have changed it already and can someone tell me if it possible? If so anybody have a video showing it being done .
Thanks
And do you want to replace the o ring on the transmission side and how to get the pipe out
Ok I have a 07 gmc 2500 6.6L.my ? Is ever once awhile my add coolant light comes on.but the tank is full I even put a black line on the tank and it is still full.and on a hot day here in south jersery it has a haz coming out the exhaust.what am I looking out or is it just me.this is my first Diesel truck.
I have a water leak behind the water pump where the 212 mmmm boats are do I have to remove everything like doing a water pump removal to change that gasket I got a little drip leak I have to put coolant in maybe every 2 weeks thanks
Hey brother so my wife's duramax has an issue. The harmonic balancer bolt has come loose and the washer that's between it is clanging back and forth against the large fan. Doesnt this mean the bolt that's in front of the washer is gone if its hitting the larger fan right ? She just brought it home and I can see the washer go back and forth when the engine is running and the fan is running
Does pc3 and water pump need to be on time with engine ?
Let's just put the bolts behind everything said general motors
o man good job. but thats why i own a 5.9 cummins change water pump 2 bolts 15 min job 😁
Why not just use a wrench on that fan nut?
