I have an 87 monte carlo with a 355 roller. How do I change the serpintine belt? do I have to pull off the alternator belt? Where do I adjust the tightness of the pullies? What tools will I need? HELP!!!!!!!!355 roller serpintine belt change?If you have a spring tensioner, then there should be some way to lever the tensioner pulley against the spring to relieve tension and change the belt. If not, then there's a belt adjustment on one of the driven accessories. Do you normally have to adjust the belt, or is it automatic? If it's automatic, then you have a spring-loaded tensioner pulley.
