Really dumb question, I know.

But of all the things I've done I've never replaced or adjusted the serpentine belt on my '89 e-series.

I slipped off the belt when I was replacing my distributor and I forgot to put it back on when I started the car. Now my belt is off one of the pulleys, a little twisted, and too tight to slip back on. I just need to losen the tension to get it back on properly (luckily, the belt still appears to be in good shape).

So, am I just turning the belt tensioner adustment nut which is vertical and just to the drivers side of the head? I haven't been able to find a pic or schematic, and I just want to check with the brain trust here before I do anything stupid.

Advice appreciated. Thanks in advance.
