well i got my jeep back from the shop. then after a week the belt started squeaking. i put some belt dressing on it while the engine was running. and if i spray it while its running the noise goes away. i thought maybe pulley.. but since the noise goes away if i spray on belt while its going . could it be? or will i just need a new belt?

 

It's possible but I would check all your pulleys. I check them by using a big screwdriver and putting it on the pulley's one by one with your ear on the handle. Just listen for the bearing noise.

 

Do the test with the engine running just put the tip right were the pulley mounts and be very careful.

 

seeing as how these things dont have a spring tensioner, maybe the belt is stretching and needs to be tightened down. just a thought.

 

Mine was doing the same last weekend, It did that for a good week, I replaced the belt with a 55$ one and the noise is gone... Can always go with a cheaper belt though.

 

dumb question. but how hard is it to replace the belt. and which pulley is the tensioner?

 

Really depends. Some of the engines have one, some (like mine) use the power steering pump as the tensioner. What year is your Jeep?
