Re: How much tension? Drive belt pulley
Even though I don’t own a 4.3, I went through something similar with my 5.7. I own a 1997 Silverado. There are two different alternators. One for a Silverado with all the bells and whistles, and one for other models who don’t need the extra amperage. Because of the two alternators, there are two different belt sizes. The difference in size for the two belts could only be seen when you use an actual belt measurement tool. When I held it up and stretched it in my hands, they looked identical but they were not.
