    Pulley & water pump question

    Alright I have a question about my Deville. Noticed in the drive-thru line the other day it was making a squeaking type noise from the front. Popped the hood today and checked it and sounds like it's coming from the water pump area. I'm thinking tensioner pulley... not a big deal and pretty easy to replace. Question is should I replace the water pump too? Reason I ask is last year with my BMW I replaced all the pulleys and belts and it still made a horrible racket which turned out to be the water pump bearing. Replaced WP, no noise. The water pump on this Deville has already been replaced in 2008 around 57k miles (107k now). Chances of water pump going bad with only 50k miles are slim, right? Figured I would ask before ordering the tensioner pulley.

    I'll check it with a stethoscope tomorrow since I'll already be replacing engine mount with a buddy (oh the joy). Pretty sure it's tensioner pulley though but there is always other possibilities.

    Replace the pulley. While the belt is off, spin the pump. If it spins smoothly and quietly, I'd leave it.

    I literally just finished replacing my WP belt, tensioner, and drive pulley because I wanted to replace it on the 4th. Unfortunately the tensioner gave out at some point on my way home from work. The belt ate/melted the drive pulley to nothingness. Turned a 20 min tensioner replacement into an hour and a half replace-a-thon. Learn from my mistake.

    Well ain't that a kick in the pants... mine was just a chirp every now and then when I pulled it def needed replaced. Might go ahead and order one for 97... only 40k but not worth the risk.

    Yeah mine isn't constant. As soon as you hit the throttle the noise goes away and it seems to be more common when the car is warm. It doesn't happen when starting it up in the morning but if I did continue to drive on it it would get much worse all the time. Ordering one next week.

    40K! Good Lord, I would not even consider it.

    Low miles is one thing, but it's 16 years old.

    Yea low miles Ranger but tires were perfect looking and blew out already. One of the downsides to low miles older car I guess is a few things just need to get changed. 2k mile trip coming up so prob get done before.

    I have found that older cars that sit more have more issues than cars with more miles that get driven often.

    Re: Pulley & water pump question

    I can understand tires, batteries and even belts, but tensioner bearings wear with miles (revolutions), not time. Replace it if it make you feel comfortable. Personally I would not worry about it, but that's just my $0.02 for what little that's worth.

    There is some truth to that.

    There is grease packed with those bearings in the pulley that will not last forever. Eventually the grease will dry up. If you have the time and $$$ why not change it. Preventative maintenance..
