HOW TO: Replace water pump in a 98 camaro..

So I hear a high pitched steel on steel noise, almost like a belt squeal coming from my engine area, I "ear" around and concluded it was coming from the water pump.

I then sprayed WD-40 onto the belt to make sure it was not the belt, the noise did not go away.

I checked my oil and it was a Quart low, filled her up and still made the noise.

I checked the clutch fluid, it is contaminated with something dark

Power steering was a tad low, but not suspiciously low...

The reservoir for "DEX-COOL" was very low, and i just added coolant
2 months ago..

last time i looked at the antifreeze when i filled up the radiator, it looked Dirty.....I'm pretty sure.


although, there is no antifreeze everywhere, i suspect it is dripping out of a location slowly... (preferably near the pump)

My plan is obviously to replace the water pump on my 98' v-6 camaro, but i am unsure on

A: how hard of a task it is

B: how to do it (go from underneath? or up top? and what to remove for easy access to replace the pump?)

C: the "correct procedure"

D: if it is obviously something else I could be missing....

thanks for your time on helping me out with my cars needs these past few months guys! Just one more thing!!

Buy a Haynes Manual for your year car. Everyone should have one. That book will help you do the job. Haynes manuals are for guys like us rather than the other books that are more greared toward auto mechanics. Also, try lubricating the bearing for the belt tensioner. They tend to make a noise when going bad. If it gets alittle better then you know it's that.

it took me about 10 minutes from the top. it was pretty easy you dont really have to remove anything just remove a few bolts (3 i think) and then take it off. im not 100% sure if it would be easy to remove from the bottom but it wasnt to hard to remove from the top.

NEVER spray any kind of oil on any kind of fan belt or serpentine belt. It will rot the rubber.

^^^ x2. yeah, not even "belt dressing" is good for the serpentine belt. If it's the belt squealing, its either a bad pulley or an old, rotting belt.

Dub Dee 40 on the belt is bad, like they said. The water pump is actually pretty easy on the 3.8L's. Not tough at all!

Well it is in a sense, they're both on the front of the engine.

ok that makes sense.
if your voltages for the BATT. on the instr. panel are reading at like 15-16 does this mean you alternator is bad? or going bad? its also making noise, and the needle for battery is WAY high then normal....i think since ill having the belt off, ima change the ALT...

Is it reading that with the car idling?
Mine is usually around the 13-15 area. I'd suggest having your battery/alternator load tested before you start spending money on new parts. Unless of course you have a ton of extra money laying around... in which case, I'll PM you my paypal, and you can send me some of your extra cash!

i have about $0.93 laying aorund here somewhere, if ya really want it
Lmao, wish i was a millionaire SOOOOO fricken BAaadd.....

And here's why:

1> we tested the voltage VIA volt meter and its at 13.82 no load, 15.** with load/ car running.
so the ALT is fine....
2> we removed the belt and ran the car to find out if it is in fact the water pump, power steering, or pulley(s) making the noise. when the belt is removed and the car running.... it still made the noise.
3> our belt was inspected by NAPA and the belt was indeed OK.

SO it could be:
Motor mount? (doubt it)
internal motor issue? (likely)
although, Ive always used synthetic oil...(173,000 Mi. on engine)

We then bought LUCAS synthetic stabilizer.

The noise got quieter....GREAT!

So it looks like IMA NEED A NEW ENGINE! YAYYYYYY

In the mean time, I'm going to look for a $300 "beater W/ a heater" for the winter as i have to save the money for the new engine...i would like to get a crate or low mile series 2 or low mile donor V-8 of some sort....

I'm just simply going to wait though until the thing BLOWS UP to worry about it anymore...i just don't care.... it starts, it goes, it stops, it turns, & it honks...its fine for now i guess....
