Thank you!
That's what i needed to know-
I will start with the belt (with all related inspections as you advise) and if the issue persists, then the tensioner.
Once again, my thanks. I can't afford to take these cars in every time something goes wrong. Wish i could as my back is real unhappy with me today (replaced an outside door handle on that car yesterday also, which wasn't fun), i guess i am not getting younger...
