Franco:

Of course, there are belt tension gauges. But, I use the 1/4 turn test. If I can twist the belt a quarter turn via hand with reasonable force, I accept it. Also, if it is too tight you chew up bearings. If too loose, it will beat up the belt, squeal and glaze the pulley. Vague, I know, but you will have to experiment. Next time, feel for the pressure required for the 1/4 twist before you remove.

Hi there,

How can I know if the tension of the alternator (and also of the water pump) belt is correct?

Does exist some instrument to measure the tension? Or the istrument is just our hands and fingers?

TIA,
