Belt squeak.....

[shanker]

A few months ago I had a 2.76 and the Billetflow idler set (using the stock belt) installed on my Cobra and I've barely driven it since. I've noticed the past few times that there is a fairly loud squeak at start up but it seems to go away after the car warms up. The tension indicator is in the normal range so I'm not sure whats up.


I can also smell what I believe is the coating on the pullies burning off like when you put a new exhaust on.

I've only put on about 200 miles since getting pullied this summer.

I'm going to see if I can narrow it down tommorrow. Hopefully it isn't a pulley but I don't under stand why it goes away. I think it may be the belt though because the belt will loosen a bit from the heat.

First thing I would do it take the blower belt off the car, and try starting the car again. That will at least let you know which belt is making all the racket.

A RR tensioner might help. I would start the car and give the tensioner a 1/4 turn and repeated till noise went away.

Belts are cheap. Throw a new one on and see if that solves the problem.

I took the blower belt off as per Carls suggestion and started it up. The squeak is definately attributed to that belt. It's funnt because it's still in the shape of the pulley configuration.

Now who stocks '03 Cobra blower belts?

You may have to order one but Pep Boys and Napa both will either have them or can get them.

I also use the stock belt with the same setup,what size gatorback belt? Or what belts you guys recommend?

I just ordered a Gatorback for $36 at Murrays. They said they would have it at 10am tommorrow.


I ordered the stocker 4080750.

The squeak at start up is typically caused by the belt slipping on the alternator pulley. The alternator is working harder to recharge the battery after the starter has drained it. When the alternator has built the battery back to normal, the load decreases and the slipping stops.
A new belt should solve the problem.

Got the new belt on and the squeak went away.

Use a little belt conditioner on it too, makes it sticky

 

[nytebyte]

Not too sure if you should use belt conditioner on a serpentine belt. It could cause it to make all kinds of noises.

I have a can of that stuff and it specifically states not to use it on serpentine belts. Maybe it's just the stuff I have.

Stock plenty of belts for your car I drive my car 3-4 days out of the week on average and Im replacing belts every 4-5 months. These cars eat belts, take a belt that was potentialy bad(squeaking) and compare to a new belt you will see that the ribs on the pullies actaully wore thru the areas between the ribs on the belt. As this starts to happen you will get the squeak on cold start ups and that is your car telling you its time for a new belt. The belt is basically slippin and causing the squeak....if you can get your hands on a gatorback i would go for it. Otherwise Gates belts run around $40+.

 

[fastcarjoe]

I don't know if belt conditioner is technically right for serpentine belts or not. It said "safe for all belts" on the can but I guess you'd have to take your chances. I get an annoying chirping when the engine is cold, the spray fixes it for a few weeks. My belt is about a year old.

The stock length Gatorback belt part is #4080750

GREAT POST!!!!

I am having the same shit with my Whipple set up. At startup idle ( from after sitting a few days) I can hear a kind of squeek noise off and on. I didnt know what the hell to think. I guess I need a new belt and maybe a few turns on the RR tensioner.
