Water Pump Replace?
I'm have been hearing some squeaking on cold startup and when shifting from neutral into drive but tends to go away at speed. I took off the serpentine belt and the tensioner pulley bearing sounds rough so I'm replacing that, also the guage on the tensioner indicates the serpentine belt tension isnt right so will replace that too, although noise doesnt sound like belt slippage and belt looks great. When I spin the water pump pulley I get a squeak and feel some resistance that a new pump doesnt make, but there doesnt seem to be very much play in the pulley and weep hole isnt leaking. Coolant level always stayed high although it looks to have gone down about 1/2" when viewed under radiator cap-it was always full. So I'm guessing I may be in the early stages of the pump going?-car has 155k, I picked it up at 120k. Not sure if pump was ever replaced. I'm thinking I could push it a little longer but I do have some time to change out the pump this week, just not looking forward to screwing with motor mount! How long do you think the water pump replace would take?
