re: Changing an alternator out on a truck.

If you have to ask…..

Since the average age of the TD poster is mid 40’s, I can see why there are so many “it’s simple” and “just go for it” posts. For the last 100 years prior to 5 years ago that was true. All last model GMC’s use one use stretch belts. A few other manufacturers have some quirky changes also.

You cannot stretch the GMC belt by hand. You must have the tool or you can zip tie it to the balancer on the right side and crank the engine and it will self seat (about 4 zip ties)….the zip ties will break themselves off.

Anyway….very vehicle specific….could be a 10 minute job, could be a nightmare if you are not familiar around an engine and late model cars.
