Chirping Fan Belt

[Matt B]

The fan belt on my coach chirps loudly everytime the air conditioner cycles. It has taken to squealing after start up lately. Comes and goes. It sometimes will start squealing when on the road and it gets hot. The belt was replaced a couple of years ago and doesn't look worn. Belt dressing doesn't really help. Any suggestions. Replacing the belt is kind of expensive. Thanks

Lat year on my old coach before i bought the new one I had the same prodlem I first tried to lub it and put some WD-40 on it it stop for a minute then it came back I foun dout that I had a leak and it was coming off the air conditing wheel itself...

Not trying to be a smart a**, but have you checked the belt tension? Maybe just needs to be tightened a bit.

It is recommended that nothing be applied to the belt in the event it begins squealing. Better just to replace the belt - again. This time I would suggest that you check the tensioner, idler and pully assemblies. A good tech may be able to read the belt to see if it's wearing abnormally.

Good advice and I will do that. Thanks
