How To: Water Pump Replacement GM 3100 V6 ( Change / Install for Chevy, Buick, Pontiac, Oldsmobile)

once I had the water pump pulley off I could see that it was wet on the inside. The coolant leak never got bad enough to see it on the ground. Thanks again!

Thanks for posting this video. My car is leaking coolant from somewhere but but not enough yet to see it on the ground. My hoses look good ( no wet spots ) so my next guess is the water pump.

Thanks zcomputerwiz, the pump went out on my 2000 Lumina and it was nice to do a quick You Tube search and find your video. Your video is quick and to the point and I could see how easy It would be to change the pump and it was. I just pulled off the radiator hose at the pump and drained a small amount of coolant into a bucket I placed under the car then reconnected it and replaced the pump. I was back on the road in no time.

Thanks again.

any way you can give a better vid on those vents and how to properly do the job on it

I own a 99 monte carlo and there is coolant leaking from what you called the vent about the water pump and the base of it, what exactly is the gasket called?

thanks for the video, my water pump is super noisy. probably only an hour or two to change it out. i bet i could go quicker though :D

There is a vacuum hose above the 3 on the 3100 toward the windshield. where does it go?

[zcomputerwiz]

@burdetterandall I think that goes into the cabin to run the climate control louvers.
