Squeaking Noise when Running

[Migorn]

Recently changed my timing belt after it went bad, and now when I start the car there is a squeaking noise. Trying to pin point the source of the squeaking noise and was curious if anyone might have any ideas.

Thanks,
Mig

Did you replace the timing belt tensioner? The bearing in it can squeak when it goes bad. I'd also take a look at all of the other belts - make sure they are in good condition and tensioned properly. You could also try some belt dressing. It could also be the tensioner pulley for the power steering and A/C compressor belt - take a can of WD40 or other spray lube and shoot it at the pulley shaft when the car is running - if the squeak stops, that is your cause and it will need to be repaired or replaced.

My squeak came from the alternator not being tight enough. Try what Jesus said first tho since that is what you were particularly working on
