Is your belt slipping Im not sure I do know 1/4" slack from the bottom of the exhaust cam gear that's right above the tensioner in the middle of the two should be Tq to 40ft lbs.
There's two belts. One runs power steering and A/C. That one you could drive without.....with difficulty, but possible. The other belt runs the Alternator. You can't drive (far) without that one.
