At first we thought it was the battery, replaced it after we checked (it was no good even after sitting on a charger), then thinking it could be the alt, so I wanna take the belt off to check. One issue, the tension is insain. I’m not sure what I can do besides either try loosening the alt first then tension or just cut the belt, which doesn’t need to be changed.
Ion know man.
What are the symptoms? Hard starting? Rough idle? Engines don’t give much warning before seizing. I’d be considering that my AC compressor is about to shit the bed. Remove the belt and start the engine for a brief period. If it starts without straining, investigate the AC more thoroughly. Been there, done that.
