New Engine Water Pump from 1AAuto.com 1aau.to/ia/1AEW...
This video shows you how to install a water pump on your 2005-2010 Chevrolet Cobalt. The water pump keeps coolant flowing through your engine. Common failures of the water pump will leave the coolant leaking, or stagnant. Both will lead to overheating if left untreated. Install a new engineered to fit water pump from TRQ for total peace of mind.

thank you for taking your time for showing every step,very helpful.

[@bovideos9751]

Thank you for this video - it's very helpful, especially with the torque specs!
One observation: when installing the new o-ring gaskets, adding some sealer would help a lot because the scraping action at 16:06 can easily create leaks.

[@erickl.r3553]

I wonder how much is the labor for this type of job?

[@oldblueshhrchannel1847]

Ok, I just performed this water pump change. Followed your directions and on start up, there is a howling noise, is it a balance shaft chain tensioner issue or a faulty new water pump?

[@ogreckless3254]

I got the same thing probably we dry started it with out cranking water into it smh

[@oldblueshhrchannel1847]

Turned out, the balance shaft chain tensioner ratcheted tighter and the guide was the source of the howling. I suggest do not use the sprocket holder tool, take the front cover off to prevent the problem, remove the tensioner.

[@pennyvillareal8017]

What's the labor cost for the water pump change?

[@hendyzero5789]

Thank you so much

[@Red4banger]

Okay I see the tool now!

[@How2Man_101]

Many thanks!

[@oldblueshhrchannel1847]

Great video.
Thanks for sharing.
Did you say the water pump is driven by the timing chain? Actually it’s the balance shaft chain that drives the water pump sprocket. Just saying.
Does 1AAuto have a full water pump kit, with the necessary gaskets , orings ?

[@JoeBribem]

Do you have a part number for that seal on the back of that thermostat block? Neither Napa or O'Reilly's has a # for it.

[@davidgibson9049]

is that a 2.2 i don’t have enough room ! did you remove exhaust trying this job on the ground

[@quikgold513]

Shouldn't have to remove manifold if you have tool sprocket holder for water pump.

[@insurancedice]

Was the demonstration vehicle a manual trans setup? My 2007 LT 2.2 with automatic doesn't have nearly the same access to the coolant pipe from below. That said, I was able to get to the thermostat bolts from the top, reaching over the passenger side.

[@aaronmenchinger]

My problem I believe is actually the crank gear for water pump. Any way to replace it without removing the entire timing cover?

[@matthewleland5568]

Ok what if I messed up and took the special tool off to soob

[@Red4banger]

Did you use the gear holder for the water pump to keep it from ratcheting tight? You didn't show it on the video. If you don't use the tool the water pump will have a whine noise while the engine is running. The noise is destroying the water pump gear, putting metal shavings in your motor.

[@spencersayo2374]

Where do I get the gasket for the thermostat housing/water outlet?

[@TRQ]

+@spencersayo2374 Thanks for watching. Buy the part in this video on 1AAuto.com: 1aau.to/m/Shop-TRQ

[@ogreckless3254]

Lol did u show the 3 bolt take with trucks its fine i mostly used this video

[@300bhp]

Is this water pump beeing lubricated by the engine oil?

[@MrLibertyordeath]

👍🏻

[@daemonsilver3304]

Not so helpful. Doesn't address the issue of holes in drive wheel of water pump not being properly aligned to bolt holes in timing socket.

[@John-yo9jz]

So in other words, take everything out back there. GM has the worst engineers

[@d21dusty72]

Very shitty engineering on this one
