Whenever I start my car, it makes a loud squealing noise that stops after a while.

I had the air-conditioning belt checked and, as it wasn't worn, the workshop put some belt dressing on it.

Although the squealing sound stopped for a while, it is back now and is worse than before. What should I do?


It is likely that your car's air-conditioning belt needs to be replaced.

Once it begins to make squealing noises and the side of the belt is glazed, no adjustment or treatment can stop the noise.

Also, check the air-con belt pulley surface for excessive wear.
