Alternator Belt Tensioner

I am helping a friend change an alternator belt on his 1995 Wrangler 4 cyclinder. I took a quick peak to look for the tensioner, and didn't see it quickly like I usually do. Can someone point me in the right direction? Any help is appreciated.

Thanks.

I got a Inline slant 6, 93 YJ and there is no alternator belt tensioner, just a power steering belt adjuster. 2 bolts, one to lock it and one to adjust. It is hidden behind the p/s hose. I just did my belt, went offroad and its now squeeking, burnt it abit :) . I have to undo the lower alternator bolt so that is pivots back, to give it slack, then I undo the ps. To hook it back up I get a long flat head and pivot the bad boy so its tight, then bolt the alt, then I adjust ps tensioner.
