6 pack and an hour of your time. THats all teh directions you need. Hardest part is getting the fan clutch off the water pump. There just as easy as a 5.7 water pump. I would suggest replacing both belts while you are at it. I have seen alot of a/c belts cracked.

Chances are you do not need a water pump but just the water pump gaskets. I see a lot of people spend hundreds of dollars on water pumps when they only needed $12 worth the gaskets.

They are the two metal gaskets on the right. GM Part number 12588372 and are less than $6 a piece.

I am revisiting this post because I replaced the water pump on my 2002 Tahoe on 5/29/2010 at 162000 miles and today I have 170000 a total of 8,000 miles only 5 months and it is leaking.

The water is coming from behind the power steering pump and dripping. I could not locate the peep hole to see if it leaking through it. That is the way you check I believe.

Can the pump go out that fast??

Would there be anything else to look at or for??

I replaced the gaskets when I did it would they be bad already??

umm what brand pump did you install, was it a new or rebuilt, auto aprts store special or gm pump. did you install the gaskets dry or with rtv? and to anser yes the pump can but it it is a higher end pump then i'd say they pump shouldn't be bad and it is a set of gaskets.


depending on the warranty of the pump i'll take it off and take it back and get a new set of gaskets with .


the weep hole should eb behind the pullie
