Just wondering...

Typically, how long do water pumps last ?


I think I blew my water pump tonight again !
I backed into my driveway, turned off the engine; & there was a stream of engine coolant coming out of my water pump area :(
(This was after coming off of highway driving for 30-minutes & the engine temperature gauge was normal the whole time.)

That is twice in 8-years with 110.8K km / 68.8K miles, that I am having the water pump changed.
(Last time was at about 5-years & at about 75k km / 46.6K miles.)

Happy 8th Anniversary (end of this month) to me :crying:

mine only lasted to 50,000 miles and it got replaced, with no problems 20000 later

I replaced my water pump on my 3100 Monte Carlo at 38k miles with an Autozone special. I'm at 116k now and its still good.

I replaced mine last year. I just picked one up at Advance Auto Parts for around $20. It's a simple fix. Just search this forum for the "how to" if you need help.

i know, old thread
so basically 50k or so is about it?

what about the oil pump?
so am i right that both of these 2 pumps are pretty simple to change? i know they are pretty inexpensive...

A normal range for water pump failure is between 60k - 100k for the first. Sometimes more frequently or sooner depending on design. For this engine though they can last up to 150k.

Replacing an oil pump is a PITA on these cars because of the design of the oil pan. Its not necessary to replace unless you're having problems with oil pressure. Usually this isn't a problem for a very long time.

Basically I've never heard of or seen a 3100/3400 that needed an oil pump..... ever. Not saying that its never happened, but in my experience there are no oil pump problems.

My original factory water pump lasted for at least 130k miles.

so are there any indications of when an oil or water pump is starting to wear out?

^ For one, I believe coolant leakage or an increase in temp are two signs. Im at 115k and haven't changed yet (knock on wood).

I had 64k on the car when I sold it. Went through 2 in that 8 year period.

and low oil pressure for the oil pump

but without a oil pressure gauge i take it by the time the light comes on... your done anyway right?
or is the oil pump just that simple that it doesnt really wear out...

90K on the factory water pump...no issues. Also have an oil pressure gauge, oil pump still looks fine too.

theres not really too much to the oil pump so i dont see it having to be replaced before something else kills the engine, unless the pickup gets clogged.

I have 182,000 miles on my 2000 gt and never replaced water pump,just lucky i guess,all original equipment,only thing i have really done to her is the lower intake manifold gasket, and i think the transmission is a little worn!

Coolant lost
You smell coolant
Feel around the water pump pully to see if it's wet.
Look at the bottom side of the hood above the belt to see if coolant has been spatter on the insulation.
Most of the time they leak alot when the motor is hot.

Our 97 3100 malibu went out around 67k. The car had 60kish on it
