well im back my 1994 jeep cherokee inline 6 is still chirping somewhere around the belt and pullys the owners before me was spraying wd-40 on the belts and pullies and the check engine light is on now... any help Thanks JayBear please

 

Hi, what have you tried so far other than WD40? ...Tj

 

Check all pulleys for forward/backwards motion, if they have play it needs to be replaced. Take a thin long pipe, when chirping is happening, place one end behind the pulleys, the sound will be amplified through the pipe. Makes it easy to find the culprit.

 

just wd-40 and carburetor cleaner and i have replaced the belt

 

You need to locate and replace the faulty pulley.

 

the chirping doesnt slow or stop its a constant chirping its like a bird in the motor lol

ill give it a shot thanks

 

Just an FYI when WD-40 get hot it gets sticky, clean it real good with some carb or brake cleaner and try some belt dressing or a new belt.
