I have a 1997 Nissan maxima with 76,000 miles and my brand new belts are squeaking. The mechanic adjusted my belts many times but the problem still persists. He tells me it's a problem with a pooley. I was wondering if I can spray some WD-40 to solve the problem. It's especialy bad when it is moist outside. Car only makes the noice for a few seconds, then the noise stops. When the engine is hot car makes no noices when I start-up the engine.

Any ideas?

 

Hell no WD-40 is a lubricant which would make your belt slip. Get some belt dressing from napa or something and spray a little bit on your belt while car is running. Before doing this you might want to rinse/clean the belts. Just put the hose in there while the car is off. Let it dry fully before spraying belt dresssing on it
WD-40 on the pulleys.... I never did and my belt squeeks loud all the time

 

i used belt dressing before doesnt work too well, i guess your going to have to get a new pulley. or a udp

 

WD-40 might work. It might make it worse. I used belt dressing spray before and it makes the belts a little sticky. It worked for me once. Didnt work the 2nd time.

Worth a try. I wouldnt change any pulleys. Nothing bad to live with a little belt squeak for 30 seconds every day.

 

DO NOT try WD-40 or any other belt spray .. i learned this the hard way a long time ago, I sprayed WD-40 on the belt in my '87 Olds Toronado and the next day my belt flew off

 

Those late 80s toronados were TANKS! Was it a Trofeo?

I cant believe GM killed Olds. It was the best quality GM car at a reasonable price.

WD 40 worked for me once. My belt didn't fly off. I wouldnt use it again though.

 

Its a loose belt, new belts just take time to break in.

 

dont know about the belt. you might want to get your pulleys checked in the dealership. these pulleys had to be extremely accurately positioned to work without noise.
