Water pump replaced now there's a noise

[23sonthetahoe]

Hows it goin,

I did the wp yesterday. As soon as I turned the key apon completion, im hearing a fairly quite squeal that changes pitch randomly. As well, wen I rev it in park the squeal gets a little louder but not by much . Can't here it when truck is moving.

Should I hv dumped fluid into the pump somehow at the upper rad hose or into the pump somehow ? Would fluid not get to the pump if I filled it all the way up top at over flow tank. Did the pump get screwed up cause it started out running dry ?

What about the belt could it be making the.noise if.its not the right amount of tension . It spounds like.its on the outside of accesories location not inside like from a pump.

Peace, James.

Ok, how old are the belts and tensioners and idler? You gave no mileage. If the belts and tensioners and idler are old I would suspect them. The tensioners sit for thousands of miles in one position and then you pry on them to remove belt(s). What brand water pump? Please tell me you did not go cheap or reman water pump.

alot of times when you distributor the belt system something else will start in. unless you started the engine before putting any coolant in the pump should be fine. i have the the same following questions as pnw vietvet.

X3 on the tensioner and belt. It’s a good idea to change the tensioner when you’re in there.

Was the belt reinstalled so it would go the same direction as before?

When I replaced my water pump I inevitably got coolant on some of the pulleys. That caused a squeal for a short while then went away.

Something else I did not ask about but has nothing to do with the noise is, did you do an AC Delco thermostat while you were in there?

Damn, I just thought of something else I meant to ask about, you did not say what year so I am gonna ask, did you replace the fan clutch if it has one? Also, don't cheap out on that part either. This could also be noise related.
