Does my belt have enough tension?

gnx547 · Sep 15, 2009

I finally got my new balancer on my 95 gt, and I'm not sure if the belt has enough tension on it. I adjusted the tensioner as much as I can with my hand by pushing it down and tightening the nut. On the water pump pulley, I can slide the belt a little bit back and forth but it does have a slight drag, as shown in the pic. Is this ok? Or does my belt need a little more tension?

Needs more tension.

Don't like the way it moves on the water pump like that.

Plus with the blower, the last thing you want is the main serp. belt coming off.

I'm missing something here. The belt is automatically adjusted by the belt tensioner and does not require any adjustments. There is a mark on the tensioner to indicate if the belt is within the tensioner limits. Did you change any pulleys such that a different size belt is needed?

Your belt is definitely too slack. If the tensioner is already at the end of its travel for maximum tension, you'll need a slightly shorter belt.

The tensioner is an adjustable one, The car came like this when I bought it. I wish I can go with a regular tensioner but I'm not sure if I can because the car is supercharged. In the first pic the tensioner bolt in front of the pulley needs to be loose to adjust the tension. I push the tensioner down as much as I can then I tighten the bolt. Getting the proper tension on this will be a pain in the butt. I will buy a shorter belt and see if that helps. Do you think I can go with a normal auto belt tensioner?

I have a KB and the stock tensioner. The idler pulley was removed though.

toyman, do you have a pic of your set up?

The idler pulley is below the alternator and to the left of the water pump pulleys.
