Got a photo of the area around the belt so we can see what you are working with? Usually, you can simply tighten the generator on the bracket on most cars.

I think... the fan pulley is 2 halves that screw together to make the v wider or narrower.  Just thinking about one the local museum has.

If so, that's the way the old VW beetles did it.  Tighten by removing the pulley nut and move a shim washer from between the pulley halves to under the nut.  Loosen the belt by doing the opposite (move a shim from under the nut to between the pulley halves).

I work on one not long ago. Yes, I believe the fellows above are right. The upper pulley is threaded. There should be a lock bolt or two that you need to loosen and then adjust it to tighten or loosen and retighten the lock bolt when it is set where you want it. While doing it you may need to turn the motor over to get the belt to ride up in the pulley and re check the tension. Repeat until it is tight enough. Dandy Dave!

Depends on the model. Mod 96 4 cyl you loosen the water pump and rotate. The eccentric will tighten or loosen the belt. 96A or 6 cyl models are different.

Hey guys, the pump on me engine is mounted with three bolts- not the five as seen on some. there is no gen pully. ??

Which engine you got? If it's a four, I still think there is a bolt you loosen on the fan pulley and turn one half. I can check on our museum car. If it's a 6 I dunno.
