- A few weeks back we did a livestream as we wrenched on our WJ - we replaced the waterpump. Today we finally have the editing done and are posting the edited version that shows the job with more camera angles!
So these are all the details to replace the waterpump. Like usual, our videos are longer than most, but we show alot of detail and talk about alot of things. Hope you enjoy!
You can also checkout the livestream that is saved on our channel, if you want to see how that went and see behind the scenes stuff as we did this filming. - Авто та транспорт
This guy is awesome and far better than most youtubers. Great lighting, great sound, logical progression, speaks English in complete sentences!
Dealer wanted ~$600 for this job. Thanks to you and your video I was able to knock it out myself ($60) and I have never worked on cars before. Heck I never even took auto class in HS 30 years ago. I don't care how much money I have lying around, I hate paying people to do things I can do myself. Extra bonus is I added a few new tools to my toolbox to complete this job. I did have an issue with it running hot after I got everything put back together. I finally figured out it was because I did not bleed the radiator correctly when I added coolant back in. Rookie mistake, but I could see others doing this as well.
How did u end up bleeding it? that’s the part I’m kind of intimidated by the bleeding 😢
My pump just went out watching you assures me that I. Ando this job no sweat! With my friends hubby on standby for muscle. FYI I'm 62 yr old female and I got this!
FYI no worries! I'm an ace mechanic! Thanks for a simple walk through ..15 mm on tensionof, 13 on the olts that hold it and definitely ely flush the radiator
The belt tensioner mounting bolt should be 30 ft. lb. of torque (page 7-18 of service manual). You mentioned 45 ft. lbs, which is for the pulley to the bracket. Mine was really hard to get off, most likely because others have made the same mistake. Otherwise a great video. Thanks for the attention to detail.
would recommend removing the alternator, water pump pulls straight up no issue!
This video was just what I needed to replace the water pump on our Jeep. I had constant problems with overheating, and I just about replaced everything. The final stop was finding this video and I was able to replace the water pump myself. Also, I could not believe I have been using the wrong Dexcool coolant all this time based on my neighborhood mechanic's recommendations. I dug up the WJ 4.7l user's manual and it clearly stated on using HOAT-compliant coolant. I gave it a flush and replaced it with Zerex G05 coolant. This Jeep has over 200k miles but it runs great now without overheating. Thanks again for the video!
Thank you! I'll be doing this tomorrow along with replacing the tensioner pulley.
My kind of lady. A jeep girl that does her own work. 🤘🤘
You can also remove the alternator and remove it through the top super slick
Same with the compressor. Either is easier I think than the tensioner
Where do the longer bolts go
I did this job twice on my Wj 4.7, the first time I did it like that, the second time I removed the Alternator and slipped it through there, made life easier than doing it across the side
I just relaxed my water pump to hopefully solve a year-long fight with overheating. This video was absolutely fantastic. Thank you so much for explaining everything and ensuring the camera was placed in optimal positions. I went into this job co rodent and prepared all thanks to you.
well done! its nice that you dont take 5 hours to explain a hour long job.. much appreciated!
Is already 5 years of uploading this amazing video and is very helpful, thanks!!
Thank you!... Great video! Heading out to the garage to do this exact job. With your insight, it will remove my guesswork.
Thank you big brother. Got it done before bed time for work
Just doing my prep before tackling a similar job on my sisters Jeep. Thanks for the video. New subscriber.
Thanks for the sub! Good luck on the Jeep work!
excellent tutorial, concise, the step by step with the vocal is perfect, thank you✌️
Best car repair video I have ever seen. Impressive! Thank you very much!
Thanks to this video i almost tear apart the timing cover of my engine, i thought it was the chain sliders and tensioners that where making the noise, but when you turned the pump pulley it sounded the same as mine does , i just removed the drive belt and turn the engine on and sounds smooth without the pump, so im replacing it as soon as it arrives, will keep the chains and tensioners for a future repair..
Thanks..
Just watching the video for fun. I’ve been using Peak All-Vehicle 50/50 coolant in mine for years. It’s a green/yellow color. Never had issues. Not sure if it’s corroded though.
Best auto repair video to date thanks
Outstanding mechanic and video coverage! Thank you you're awesome!
Awesome, and thank you! Glad it was helpful!
Best video out there for the water pump. Guy is amazing
Just noticed mines damp, looks like im doing a waterpump thanks to your vid, nice work bro thanks
Great video, just used it to change my pump. I was unable to get the tensioner bracket off so I took off the idler pulley to access the bottom pump bolts. Also, I took off the plastic arm the holds the AC line and unmounted the alternator and got the pump out today way. Hope you make some more videos.
Great video. Helped me change my pump . took me a bit longer then him though .
Thanks for uploading; helped a lot
You set the standard for good UA-cam video. Do list the camera, lights, and audio you used. You did such a nice job in presention alone I am impressed. Certainly the information you record was very good. Since you have all the best tools at hand; with just a little more effort you could have shown how to remove the fan shroud and make it even more easier to work.
Another suggestion, since I love you and what you to be great, again; try to record clips of jobs that have a value in itself. Like removing the belt by turning the tensioner. Then link small clips of the videos together to do more complex jobs like water pump replacement. Soon you will be able to rebuild the whole engine. Jeep Cherokee is a good baseline model to do this.
With my high regards.
Great video, it’s very straight forward and helpful. I need to replace my water pump and I just had one question. For whatever reason the previous owner welded the bleed hole at the highest point shut so I won’t be able to pour coolant in from that point. Is there another way to refill my coolant without needing that hole?
This was very helpful thank you!
Nice job. Thank you
Great video! Very detailed! Only one thing I would be concerned of , you may have caught all the clean fluid in the drain pan from the rad, but I would then remove that drain pan and put other one underneath there to catch whats coming out when you're removing the water pump bolts and water pump. That fluid that's draining down the motor into the pan would get dirt in it from the exterior part if the motor. And just disturbing those bolts alone would dropped dirt into your clean fluid.
Subscribed for the high quality content. Great job
Awesome, thank you!
Thanks alot for your video
Very good video 🎉
Do you need to account for a heater core bypass when adding coolant? Thanks in advance
I just did one today that was 150k miles and pretty much bearing exploded on water pump. I unbolted the three bolts for the AC Compressor with the lines and clutch plug still attached and lifted it straight up to get room for water pump. And for refill I took out bleed plug and filled via radiator till it flowed out of the bleed screw and then reinstalled plug, started up truck with heater on to feed the core and then put the radiator cap back on after it started to warm up.
Great minds think alike. I moved the compressor and it was super easy. Like you said, 3 bolts and disconnect one connector and you can set it off to the side.
DISCONNECT THE POSITIVE BATTERY TERMINAL , UNBOLT THE ALTERNATOR. WATER PUMP COMES RIGHT OUT THE TOP. LEAVE THE BELT TENSIONER ON TOO.
Great video thanks, but i removed the alternator (3 bolts 1 nut for power n unplug 1 clip 5-10 min.) then the water pump came out so easy . Thanks again
I was told that was easier, I'm thinking of trying to do this job myself
Geez, I wish I would’ve read this before I tried removing the tensioner. Stripped the dang thing. Hopefully I never have to replace it lol. I finally came to the realization that you can pull the alternator through trial and error. Hopefully you didn’t have to find this out the hard way like i did :(
Lol I was thinking about upgrading my alternator too when I do mine tomorrow
I bought a Gates water pump with an aluminum impeller and a Gates belt tensioner and belt..from Rock Auto
Do I need the water pump with fan clutch on my 2000 Jeep 4.0 or just the duralast mechicnal pump
Great video. What year Grand Cherokee is this?
Can someone helpe me pls.
I have jeep WJ 8 47 I replaced the knocking sensor and after that I feel no power in the engine like before and find air in cooling system. Is there a relationship between knocking sensor and cooling system
Great video. Answered all my questions before replacing mine. Why are your out loud narrations the same as the in my head narrations when I do stuff on my jeep? :D
I have the factory tow package so I has the hydraulic fan and electric fan. I would love to be able to do my own water pump replacement but I have two broken screws in my back so I can't, which stinks because I love wrenching on my wj.
I was wondering why there isint 2 cooling fans on most of these diy jobs on the 4.7 here on UA-cam...then i discovered that the towing package is equipped with two fans
i did not know i needed hoat coolant ive ben using orange color oat preston. should i keed using the same or can i mix with the hoat coolant wothout any issues? thanks
Tira uma dúvida, a hélice e viscosa não tem?
How much would you torque your bolts down on ur tensioner pulleys. I got new pulleys on my tensioner and am unsure how tight i need the bolts.
Can power steering pumps leak?
At long stops or heavy traffic, my temp gauge moves too hot. The engine cooling fan fails to come on and if I don't move as soon as possible my Jeep (4.0 straight 6 2004) runs hot. I think the thermostat is stuck closed. Help!
Great video...where did you get that light your using for the hood, looks like it works good
Sorry for the slow reply - thanks for your comment btw! Regarding the underhood light, I got it off Amazon. It's an ATD 80357.
It is night and bright, and is flourescent. There's many more on the market now that are LED. Eastwood has one that looks interesting as it splits in half for different configurations. But I do like this ATD light, it gives great light output and does rotate to help put light where needed.
Vortex Garage thank you
maybe the weight of the cooling fan is stressing the water pump bearings
Why does my 4.7 have 2 cooling fans?
Seems
Awesome video. My WJ went down this weekend and I’m more than positive it’s the water pump. I was able to safely get home. Unfortunately it won’t start at all now. Would a failing water pump cause it to start at all?? Thanks b
What makes you think it's the water pump? Did the Jeep overheat? Other symptoms? I would say that a failing water pump will cause the noise from bad bearings, or perhaps and overheating condition if it leaks badly. In a really bad scenario of water pump failure the impeller can seperate and stop water flow, causing an overheating condition. Bearings could also seize completely and toast the serpentine belt but I've not seen that on the handful of WJ's we've had in the family.
I don't think a bad water pump would prevent the Jeep from starting. However if it overheated badly, that could cause it due to other issues. I'll caution against letting the 4.7l overheat - I drove mine home (I have a get home no matter what gene!) when the thermostat had failed, and it ran hot for several miles during some stop/go traffic. A month later I was doing head gaskets...iron block and aluminum heads don't like to overheat due to their differing thermal expansion rates. Best of luck with yours, and overheating isn't a guarunteed head gasket issue, but it definitely ups the risk, so I have learned since then to immediately park an overheating 4.7l.
When you were putting the coolant back in did you put it in the reservoir at the same point you put it in radiator and the high port or did you fill the reservoir after?
I add in the top port as in the video. Afterwards check the expansion tank and top off if needed. Usually I find it is at the correct level. It's not quite a reservoir but an expansion tank. As the coolant heats it expands and goes into that tank via the small hose on the top of the radiator. When it cools and contracts it pulls it back in. So really just check it and top off if needed after filling in the small top port in video
I ran into the problem of having two fans? A high flow fan connected to the water pump, and an electric fan connected to the shroud. This had me take out the radiator to get the water pump and fan off together. Why didn't your model jeep have this fan??
you didnt need to do that , i have the fan clutch assembly , and electric fan . all you need to do is take the fan clutch assembly off , and drop it straight down it comes out very easy .then you have all the room you need.
"The bearings seem to fail every 2 years" - Then why keep buying a cheap pump? I just checked Autozone and their Duralast water pump is $62 (of course their Duralast Gold pump is like $82). You can get a Mopar OEM pump for $94 and I'd bet anything it will last a lot longer than the Duralast will.
Yeah, but the duralast has a lifetime replacement, so you’ll never buy another one
@@051biohaz But is that worth having to tear into the engine and perform the job every 2 years, to save 30 bucks? I'd rather do it once and not have to worry about it, likely for the remainder of its life. My WJ has its (presumably) original water pump and it has 148k miles. That's a damn good amount of time, and it doesn't appear to be letting up, but since I'm about to do a preventative overhaul, I'll go ahead and replace it, but I'm actually going with a Melling. BTW, you should buy your car parts from RockAuto.com if you can, their prices are insanely good. I'll never go to Autozone/Oreillys again if I don't have to, their markup is crazy.
What if you also have a mechanical fan attached to the water pump?
I have the same thing
I have to replace the radiator so will also replace the water pump. No trouble for 133K.!
I did have it get hot several times and did not realize about the air bubble set screw. Mechanic got me going and no more overheating. Seems like a strong engine.
Did you add coolant to the overflow after you were done bleeding it?
When done check it and fill if needed. I had relatively new coolant during this job so checked and it was at correct level after filling.
i didn't see where you mentioned the fan clutch ?
I know there were several different combinations of fans on WJs but the 2004s with the 4.7l V8 I've serviced, none has a mechanical fan with fan clutch. They all used the hydraulic powered fan. Now the inline 6 motors do use the mechanical fan I know but the water pump is different on those too. Hope this helps some
Ima be finagling my ass off tomorrow. Fan clutch and water pump possibly
weird. the Jeep I'm looking to work on also has a mechanical fan attached to the WP pulley.
Jeep had several different combinations over the WJ run. I believe though mechanical fans with auxiliary electric fans was normally on the 4.0 inline 6 models. Water pump job on those is also different as it's a different part and engine family
@@VortexGarage it was the Grand Cherokee Laredo. That might be why.
Is that a 2007 jeep grand cherokee?
does a bad water pump cause the engine to over heat?
Usually a bad water pump will make bearing noise, or leak coolant. In some cases leaking can cause low coolant and overheating, or in more rare cases the impeller will fail causing overheating. On a WJ, the thermostat is a common cause for overheating. Either way would require some diagnosis to be certain as there can be several things that can be the root cause for overheating.
My 4.7 V8 says DeX-cool. Is that HOAT compliant or whatever. ?
I have never heard of a Jeep or Dodge 4.7l calling for Dexcool. While Dexcool is primarily a GM coolant, I do know that recent Fords use a coolant that is basically a Dexcool standard. It's possible that later Mopars have similar? But every WJ I'm aware of called for HOAT compliant coolant, not Dexcool.
Zerex G-05 is what I've used each time I've done a WJ 4.7l water pump.
JeepForum.com is a great place to also go post and see if anyone else has come across this, but again, I've not seen that personally.
Loosen the high pressure power steering hose so you can move it and pull the wp strait out.
Close the drain valve and move the pan. Get a new pan to catch the wp fluid that drains down.
Is it the same process if your fan is connected to the water pump?
Alberto Gonzalez Close but it will be different. You'll need to remove the mechanical fan from the water pump
Vortex Garage oh thanks. Its the same as removing the bolt from the water pump right?
Alberto Gonzalez you have a 6 cylinder? Removing that fan is different than the water pump bolts and the water pump is also different. I did remove a 6cyl mechanical fan in this video ua-cam.com/video/XZIPQNwGUi0/v-deo.html
Vortex Garage i have a V8
What size was the fan clutch wrench?
You didn't show whether you took off the fan
This configuration of WJ does not have a mechanical fan to remove. It uses a hydraulic powered fan in the radiator shroud assembly and it does not need to be removed to replace this water pump. The inline 6 WJs do have the mechanical fan that is removed for a water pump service but these specific 4.7l V8 models do not. 😎
Eh I have a clutch fan and an electric on my 99 4.7
my 2000 has 4.7 has a mechanical and electric cooling fan
Mine does too
Mopar water pump on these are junk. They use a plastic impeller and crap bearings. AC Delco is a great upgrade. Heat treated bearings that last 100k miles and has a metal impeller. I would not use a Mopar replacement or similar. Go with the Delco.

A lot easier to remove the pulley, instead of the whole tensioner.
I agree the idler pully not the tensioner pully
Who needs a work uniform
Anyone going to do this; remove the alternator, its a lot easier.
YOU TALK TO MUCH > JOSH /
*too
What does a guy do if there is a fan attached to the water pump?? Just can’t figure out how to get the fan blade off
