I got a 92 s 10 2.8 with almost 200000miles . last time I changed the belt the smog pump pulley seemed a little stiff. Can i bypass it .if so Anybody know what size belt ..would this help or hurt performance and gas mileage
It might mess up your computer. If you don't have any computer go ahead and bypass it, my buddy has one on his ford and found out it is better to get rid of it but it may be illegal in the state you are in.
