So I bought my car to a shop today to change my Timing belt/water pump/belts/ and seals. Its a 99 Civic Hx. Before I had the timing belt change it ran perfect and the idle was very smooth. After the timing belt change it makes alot of noise at idle but while Iam driving it runs perfect. He told me it was because my AC clutch Bearing is loose and so was my old timing belt, thats why it didn't make any noise before.

Could a loose AC Clutch bearing be the cause?

 

Whoever did your t-belt is full of sh-- They got the belts too tight. Take it back and tell them to adjust the belt properly. That will fix your noise.

 

I have to agree with this ^ guys firts post. Belt too tight, don't believe their

 

You might want to pay the extra money for a better shop to take a look at it.

The reason the original shop didn't do it right is because they don't know what they are doing.
