I need to know how to loosen the tension belt (pulley belt) on my L so I wouldn't brake it. I have a 6lb to put on.

 

I don't quite know how to answer the question, because changing the belt is a very easy and straight forward operation. If your are just replacing the belt, you'll find that the belt tensioner has a 1/2" square hole in it to fit a 1/2" breaker bar or ratchet. Loosening the belt is very easy accordingly. But you also say you have a 6# to install. The 6# takes a different belt than the stock pulley, so if you're installing the pulley as well the project is bigger. A 6# also requires a reprogramming of the ECU or the motor is toast. I also should have an intake system and a few other changes as well........

 

kerno you said A 6# also requires a reprogramming of the ECU. I just spent some $$ for the PREDATOR is that a good choice.
