2011-2015 Chevy Volt - How to Replace Engine Water Pump
Вставка
- Опубліковано 29 гру 2019
- This is a tutorial on how to replace the engine water pump on a 2011-2015 Chevy Volt. Torque specs included.
I didn't "need" the cherry picker, but one of the steps to remove the right engine bracket is to "install engine support fixture." These install from above, so I chose to use the cherry picker instead of jacking up/down the engine from the oil pan.
It wasn't too difficult to get at the 3rd lower engine bracket bolt, but to break it loose was difficult and even more difficult to remove it. The engine needed to be lowered as far as gravity would allow it and then the coolant lines along the passenger frame rail need to be moved down to squeeze the bolt through. The frustrating thing about this whole job is that belt is supposed to be changed every 150k miles/10 years and short of replacing the water pump, the steps are identical. Reinstalling the belt was also way more difficult than it should have been too. The manual says to turn the crank shaft, but there's no room to reach it from above to also guide the belt onto the water pump pulley. I opted to turn the water pump pulley instead with a crescent wrench and it was much easier.
Reassembly was challenging as well, but I believe it was easier than disassembly because I knew what I was doing.
Estimates for this job costs $800-$1,000 in my area. I would say you don't need a highly mechanical aptitude to accomplish this task, but it wasn't particularly easy either. It took me 3-4 hours.

Thank you so much my local shops and Chevy dealer wanted to charge me an obscene amount of money to do this and charge me extra for changing out that engine bracket like you guys already have to take it out when you do the water pump bloodsuckers
hey they had a bailout and still bend us over freedom ain't free
Thanks. I already have the belt waiting to be swapped. One of these days, I will buy the water pump and with your tutorial, it will be easier to do this myself. 2012 Opel Ampera with 182000km.
You are welcome! The belt is supposed to be replaced every 150k miles or every 10 years, whichever comes first. Good luck!
Thanks for posting this. The dealer wanted $1100 to do this job. I just completed the job thanks to your video. I wouldn't have tried to tackle this if I had not seen your video. I did one thing different than you did though. I did not fully remove the lower bolt on the engine mount bracket. By jacking the engine up high enough I was able to remove the water pump without fully removing the engine mount bracket. Loosening that lower bolt was the hardest part of the entire job. Also, there are three different length bolts on the water pump. I highly recommend people to make a diagram to locate these bolts as you remove them unless you have a shop manual.
You're welcome. I watched a video on changing a water pump on a Cruze and assumed it would be similar and it was, however, there is more room under the Cruze hood. Thanks for the tip on the lower engine bracket mount bolt. I hope I don't have to do this ever again, but that could spare some time. Yes, definitely need to keep the three different length bolts in order. As I removed them, I placed them into the new water pump holes so I knew where they were going upon reassembly.
Thanks! Thi was a superb video to file away for a rainy day. Great Job!!!
You are welcome! I'm glad you liked it.
That’s quite some job. Thanks of sharing
You're welcome! 👍
Great video thanks .
Great video. Thx.
You're welcome.
Glad you were successful. For me this job will be done by a pro.My days of this type of car work have passed.
then pay top dollar my friend!
perfect
Think I am about to do this... gonna hit you up on the FB group.
Thank you very much for this video. Tackled this myself but still struggling to install the new stretch belt. I dont know how you managed to do it with just your thumbs while someone turns the crank. Tried the Lisle tool but its grooves arent wide enough for our pulley. Hmmm...
You're welcome! Reinstalling the belt was way more difficult than it should be. The manual says to turn the crank shaft, but there's no room to reach it from above to also guide the belt onto the water pump pulley. I opted to turn the water pump pulley instead with a crescent wrench and it was much easier.
Thank you! Yes I had an assistant turn the crank while I turned the top pulley. I have a trick to doing this now- it takes less than 2 minutes. Take one of the pulley bolts out, and put a zip tie through it and around the belt TIGHT. Turn both pulleys and cut the tie once the belt reaches the other side. EASY
@@ezdeezytube Nice! That's some good improvisation! Glad to hear you got it on.
Just finished 5.5 hours.
1 hour in had the replacement pump on......and then the belt took 2 hours..googled the trick for stretch belts, boom, reassemble...and realize I have the pulley screw in my pocket 😥.
Can do it under two now and will add a supplement video for a couple of small things that helped.
Glad to hear you got it replaced. Looking forward to some tips and tricks you learned along the way. I had the service manual, but sometimes that's not always the best way.
@@mjspiess just finished the Tips video

@@ChuckMorton Thanks for sharing! I like the zip tie trick! Keeping that lower bolt in should save time, especially if you can fit the pump back in with the bracket still in place. Nice work!
@@mjspiess thanks, just don't be an idiot like me and forget to put that bolt back.
I also used your heated seats video to know that the leather/upholstery want to hard to get to and fixed my sensor
@@ChuckMorton You're welcome. Lol noted!
Nice! I'm glad that video helped you too.
I heard that the engine mount bolts might come loose if they're not replaced. This was from a local GM service tech. There were a couple of cases where the mount came loose so the recommendation was to replace the bolts too, not sure if this was GM official guidance or not. Did the bolts seem anything special to you, like single use stretch bolts? I wonder if I can just use blue loctite on the threads to make sure it doesn't come loose.
I believe the service manual mentioned replacing the bolts, but I just reused mine. The bolts didn't appear to be special in any way. It's been 2 years/36k miles since my repair and they have not come loose. Blue loctite seems like a good idea if there's a known issue with the torque remaining tight.
If the belt ever needed to be changed you'd have to do all this with the motor mount minus the pump swap, correct?
Correct... Not a particularly easy job, but doable.
Thanks for the video! I’ve been told you need a computer program to burp the system properly, I didn’t see anything regarding that in your video. So I’m assuming that is not needed?
You're welcome! Correct, it's not necessarily needed. It will take a week or so to naturally bleed, so just check the coolant level each day until it no longer drops in level.
Awesome thanks I appreciate it. Mine has been leaking for about a year from the weep hole. Just a little. Didn’t have to fill up the coolant that much but it finally went out. Been dreading this but now my mind is at ease.
Thanks again.
@@timothyarnold162 You're welcome! It takes some work to get to it done, but it's worth the effort to save some cash. For sure. Rest assured, you don't need any of the special/expensive equipment to get this job done.
Thanks again for this. I just got all the parts in yesterday. A few things were on back order.
This wasn’t bad, not sure what they were thinking with that bottom bolt on the mount. Such a pain in the ass... would probably be an hour job if it wasn’t for that bolt. I started it up got an error message but cleared it. Hasn’t come back as of yet so knock on wood it won’t..
Anyways thanks again I appreciate you making this video.
@@timothyarnold162 You're welcome. No kidding... That bottom bolt on the mount is rough! Good to hear on the error message. When I replaced the front radiator when I first bought the car, I had to clear the code every time I turned it off, then on. However, after about 3 weeks of adding coolant little by little, it finally never came back. Then a few months later, the water pump began leaking lol! Anyway, I'm glad this video was able to help you and many others.
Was the water pump oem or aftermarket? My pump just went and am looking replacements
I used OEM from Rock Auto.
Can you help me locate the engine coolant temperature sensor in a 2014 Volt? I'm getting an error code P0118 associated with "AC Off Due to High Engine Temp". Thanks!
Yeah, it's a tight squeeze, but it's on the passenger side of the engine radiator. I go over the process of removing it in a different video when I replaced the radiator: ua-cam.com/video/TE9z5cPZaTk/v-deo.html
@@mjspiess thanks, the diagram for the part I purchased (ACDelco# 55591401) shows it on the water pump assembly.
@@edwinreidel1889 You're welcome. Yeah, there is no sensor on the water pump. That sensor you bought is definitely on the side of the radiator.
@@mjspiess I got it done, although it took A LOT longer than expected. Next, I went to change the oil and the drain plug wouldn't budge. Finally the bolt head started becoming rounded and I just decided to take it to the lube service. It's scary getting under those heavy rigs. Thanks again for your help!
@@edwinreidel1889 These Volts are not very easy to work on! Oh man, probably good call on taking it in after you started rounding the bolt. I've had pretty good luck using a 6 point wrench and tap it with hammer or even use an impact wrench on it just to break it loose. You're welcome for the help. Glad you got that done and saved some money!
Does the engine need to be picked up to do this or was it just easier that way?
It needs to be supported from above or below because the passenger side motor mount is temporarily removed.
@@mjspiess thank you. Have to tackle this one over the weekend unfortunately
@@bb8384 You're welcome. Unfortunately, there's nothing particularly easy to repair/replace on these Volts. Read through my description and other comments for more tips. Good luck!
How long did it take you in all?
3-4 hours.
@@mjspiess it may take me two years
@@wuyuebing yikes! Might want to let someone else handle it then.
I have everything here to do the job.. But they keep telling me I need special tools.. Is that true?
I did not need any special tools, unless you consider a torque wrench a special tool? I chose to use an engine hoist, but you could use a floor jack, but make sure you have a wide base of wood to support the engine so you don't damage the oil pan.
Also they have two torque to yield bolts that are 2 3/8 inches long that are needed to replace in dealer quote but it is not seen on your video. Was curious as to where they go and tourque specs as well. T. I. A.
I assume those are the engine mount bolts? If so, I reused them and have not had any issues.
It's interesting, my mechanic insists that 'the book' (some subscription) says you need to disconnect orange cables to do this procedure, but u didn't!
Hmmm, I'm not sure why you would need to? The engine water pump has nothing to do with HV system and is on the opposite side of the engine of the orange HV cables.
@@mjspiess he clarified, Having to raise engine for lower bolt clearance, so much that risky not to disconnect but looks like they ( big orange inverter/trans) have enough slack maybe rear small orange cables could be issue 🤷♂️ thx!
@@danwat1234 Hmmm, I'm not sure, but it's definitely not necessary to disconnect any of those HV orange cables. Plenty of slack.
@@mjspiesswell even though he has seen your video he still wants to go by the book, disconnecting orange cables to replace water pump and do a head gasket job. And he isn't comfortable doing so since he isn't trained on high voltage, making sure capacitance is gone after pulling orange breaker and disconnecting lead acid first.
So, off to the dealership I go.
@@danwat1234 Bummer. Hopefully they get it all sorted out for you.
Why does the engine even HAVE a water pump; the electric part of the car already has a coolant pump, just make it bigger..?
The engine has a water pump because the engine creates heat and it is cooled by its own radiator like any other standard internal combustion engine. The electric pump is for the battery and electric motor. Both systems work independently and dependently on one another and both require their own cooling systems.
@@mjspiessmaybe he is talking about the water pump for the heater core loop. Which is the one by the passenger side wheel
@@danwat1234 That could be. I haven't had to replace that water pump yet.
Well…looks like I’m going to the dealer lol. Apartment complexes aren’t ideal for projects like this…
Lol yeah, this is kinda a big job for an apartment lot. Good luck!
I was thinking I'd clean my throttle body but it's way down in there! Oh well. At least I'll get to change my own spark plugs lol. They made it so difficult to work on the engine GM sucks so bad
Sure is! Yep, spark plugs are easily accessible, but in general, things are pretty tight in the engine bay. I watched a water pump replacement video on a Cruze first to kinda get an idea of what this was going to be and there is a lot more room to remove that engine bracket on the Cruze. Overall, I've been very happy with my Volt though. Good luck!
@@mjspiess alright I looked in there and I think if I remove the air filter the throttle body should be accessible for cleaning. I have no clue how to get the throttle door to stay open on a hybrid lol. I'll give it a try when the weather cools off.
Most new cars are like that. A bitch to work on.
Sorry the warranty does not cover the water pump
That's a bummer! If you're in the area where a mobile YourMechanic.com technician could come to you, it would be cheaper than going to a shop or dealership. I think the mobile mechanic quotes out around $750 for water pump, belt and thermostat or $575 for just the water pump.
So much plastic🥺
I know... It's frustrating, but pretty standard with all makes at this point.
