Having problems with your 1985 Ford Mustang ?
When the belt is on my 85 mustang it makes a loud hi pitch noise. when u take the belt off it stops. i replaced the tensi,belt,alter,and water pump with new ones and it stopped. for about 10 miles and it started again got any idea. i dont have no more ideas. power steering works good and the a/c comp is not on when this happens
IT,S YOUR PULLEY THATS BAD
The ac not being on does not mean it is not the cuase of the noise. The bearing may be going bad on the ac. You may want to take a look at the idoler pulley as well. They are the same as the tensioner aside from the fact it is hard mounted. Try spraying a lubricant on the idoler and if that does not help spray the ac at the cak of the pulley. Which ever ones helps will let you know which is the cause.
