Ok i have been reading a lot of thread on a lot of forums and I can't find the exact answers to my questions. hopefully yall can help.

My car whines and squeaks. it is coming from up front. I am fairly sure it has to do with the belt, idler pulley or tensioner pulley. I have a 2005 mustang gt. It drives me insane listening to it and it is so embarassing. Is my idler pulley ribbed or smooth? what would u all say I need to replace? I had a guy from a shop show me that when u pour a little cup full of water down onto the belt, it goes away for a few seconds to a couple minutes. IDK if that helps any. thx for a speedy response.

 

OP,

It's impossible to just assume which pulley, idler, etc., is loose from just a description. The best thing to do is take the belt off and spin each one by hand. You should be able to get a few squeaks out or feel a resistance when spinning the bad pulley. Also, hows the condition of the belt? A worn out accessory belt can cause squeaks, too!

^^^^ yup^^^^

I have an idler wheel that dosnt last long before it starts to squeak, when car is 1st started, because its behind the SC & mounted to engine block and gets hot. PIA to change.

 

Please makes sure you know the whereabouts of your cat before you continue troubleshooting this issue!!!

 

If water will make the squeak go away, then the problem is the belt. Try a Gatorback belt. Worked for me.

 

^^ that's promising. I'll change belt. See if it squeaks. If it does ill replace a pulley.
