In this regard, how tight should my drive belt be?
The required measure of tension in the serpentine belt is that it should not deflect more than ½ inch when twisted either way from the middle. If twisted more, the belt is loose, and if twisted less, the belt is too tight. Either of the positions does not work for the vehicle.
Beside above, can you tighten alternator belt too much? If your belt is too tight, you could shear the bolts of the pulleys, or the belt itself might break off while you are driving. You will need to adjust an alternator belt whenever it has been removed from the car.
Correspondingly, how do you test a drive belt?
Here are tips for inspecting belts:
- Look for cracks, fraying, or splits on the top cover.
- Look for signs of glazing on the belt's sides. Glazed or slick belts can slip, overheat or crack.
- Twist a serpentine belt to look for separating layers, cracks, or missing chunks of the grooves on the underside.
