I figure the hellish screeching coming from under my hood is my
alternator belt, as it stops after 20-30 seconds and the battery is
getting sluggish quickly. Problem is, being an idiot who still wishes
to save money, I don't know where the tensioner is on my 93 Nissan
pickup. It's been going on for a while so the belt pulleys may have
polished the underside of the belt by now, but I want to try tightening
it before I hand out cash to get the belt replaced. My mechanical
inclinations extend to where the key goes and where the gas nozzle goes
and, well that's about it. I am a whiz at presetting radio stations but
that has nothing to do with my problem. Simple steps would be
appreciated. Thanks
