Had mine repaired 2 years ago and it is doing it again! Have had a service high voltage charge and charged $1700.00, had extended warranty is probably why they charged so much.

Had mine replaced first time but started vibrating months later. It was replaced and now there is no heat again, this will be #3 under 55000 miles. Cheep parts used by GM!

This video was fantastic. Saved me $500+ in labor! The only part I needed besides the pump was a bunch of plastic clips I broke trying to remove them. Thank you for posting this video! Good to have electric heat again.

Great video. This video covers everything I needed to know including correctly diagnosing the problem, ordering the right part and then getting it done efficiently. Nice to have heat in the winter here in Colorado. Thank you!

Super handy instruction set. I did it in less than 2 hours thanks to your instructions. Tip to save coolant in case you do not want to drain it... 1) loosen the hoses with pump in place, so you know you can remove them 2) remove pump completely, except the hoses are connected 3) remove each hose and quickly swap to the new pump, pinching the hose to limit leaks. If you decide to plug them, conveniently the hoses are exactly the same size as the factory lug nuts on my Volt.

@@golfish8589 Yes. Same symptoms, but you can have more than one cause. In our Volt, the heat failed only sometimes, and then failed more often. The electric heater uses the same coolant and heater core in the cabin as the standard engine heater. The computer decides if the flow should go through the engine to get heat or through the electric heater. There is an electric pump and a y-valve. If either goes bad, the electric heater will sense that it is in hot water, and stop taking power. At the same time, the coolant is not flowing to the cabin heater core, so you are still cold. You can run the heat and feel the hoses and see where the hot water is. I believe a bad valve will show the same symptoms as the bad pump. In most cases I have read, the problem is not the electric heater element itself. It is a tricky problem to track down, but the pump is a cheap and easy, so a good place to start. I was lucky that was the only problem.

This is the exact problem I'm having with my 2014 Volt right now. Thanks!

Thanks for the video! The two pointers I'd add: 1. I needed a deep socket (10mm I believe) to remove the two nuts holding the pump in place. 2. The hose clamps were sort of bedded into the hose and were easier to remove once the pump was detached from the bracket and I could get a better angle to give the clamps a firm wiggle back and forth, with a bit of oil on the hose. Enjoying my heated all electric commute once more!

A great guide for this repair! I’d add that some of the small screws might snap off (4 actually did) due to corrosion. A trip the the hardware store was the only glitch to this time wise. Thanks!

Fixed my heat issue. Thanks for posting!

My favorite color for the Volt! It's a pretty easy change. Oddly I've read where people have been able to get the dealer to replace it under the Voltec warranty. The dealership I took it to said it was not covered under the warranty.

Very helpful. I really appreciated you taking the time to video this diagnosis and repair. I have a 2015 Volt, just now getting 114k miles on it, and aside from frequent CV joint replacment, this is the first item that has needed repair. Saved me $600 labor quote from Chevrolet. I did have a very difficult time getting the cover for the electircal plug removed, and as well, the plug did not want to come off, and yes, I did pull back the white locking clip. Almost broke it I think prying on it. Speaking of the frequent CV joint replacement, has anyone else had this experience. I had to replace them at 45k miles under warranty and again at 90k. But they were clicking again already at 105k I suggested to the dealer that the last CV joints they put in could be considered defective only lasting 15k miles, but the dealer said no luck, and I'd have to come out of pocket for the repair, since my 100k drive train warranty had expired. I have just been going easy on acceleration around corners and getting the joints to last as long as possible.

Great video! I have error P00B7 and no coolant leaks in my 2012 Chevy Volt. I just replaced the thermostat, but it turns out that was not the cause of the problem. I do not get heat even in Gas Engine mode, so I do not suspect the heater pump your video shows. All I can guess is the Water Pump is not generating enough flow... the vehicle overheats when in Gas Engine Mode. I cannot imagine that the Heater Control Valve you showed in your video would cause an overheat engine condition if it is blocked, could it? Can you think of anything else that might cause the engine to overheat and no hot air coming into the cabin?

Hey, great video. Is that pump shared between interior heating and battery heating? I have a problem with battery heating, it doesnt seem to get warmer (get up to 13-15C degrees) and because of that car keeps running on gas generator. Even when its running on the gas generator, it gets warm inside but the battery remains cold, and only when it gets up to 18~ degrees it starts using the battery. On city trips it generally means it never gets that temp, only when I have a longer road trip it worms up and switches to the battery. When it gets warm outside the car functions without problems.

I didn't. ;) I figured because I plugged the lines and didn't have to add any fluid to it, it would be ok. The gamble was the little bit of air in the new pump would work itself out.

Is this the same troubleshooting for a 2018 Volt?

Do I follow same guidelines for ELR...purchased pump for $180...

I did take it apart and what I had found out was the propeller was glued to a magnet. Both parts are submerged in coolant and over time the glue deteriorated and came loose from the magnet. It probably could have been glued back together but I chose to just replace it.

So many issues with cooling systems could be avoided if people actually maintained their vehicles according to the manufacturers recommendation. Hardly anyone flushes their coolant systems out, flushes brakes systems out. It's only when something goes wrong (sticking thermostat, leaking heater core, leaking radiator, or worse...blown head gasket) that the coolant gets changed. I believe the coolant PH changes over time and starts attacking the internals of engines and associated components. I believe the organic Dexcool is especially prone to turning acidic and wreaking havoc on internals.
