Yes, if the belt tension is not tight enough it won't spin the radiator fan due to slippage. Replace the tensioner pulley.

How much fan belt for 1995 Jeep Grand Cherokee Limited?

The fan belt that you need will be determined by your make and model and can be had by going to a reputable parts store and just telling them what you are looking for. You probably won't find a belt at Walmart types of places. On this forum you will find information about the belt tensioner pulley and how to change out the belt.....its an easy job but you need a ratchet and a socket of the size that will fit the nut on the front of the tensioner pulley.....you use the ratchet to release the tension on the belt so that you can slip the belt over the tensioner pulley, the last step in the process. Sorry, I don't know what size that socket is but the parts store may. By the way, the tensioner pulley is the only pulley in that mess that doesnt actually drive an engine device (such as the AC, fan, alternator etc). It is spring loaded and keeps the serpentine belt under tension so that all the other things work correctly. This is a job that anyone can easily do but it does help to have someone there to help you: one to push on the ratchet and the other to slip the belt over the tensioner pulley. Good luck

If water pump tensioner is bad on Jeep Grand Cherokee can it overheat?

This is a serpentine belt that runs all of the pulleys on the front of the engine. There is a separate tensioner pulley and not one for the water pump alone. A bad tensioner will allow the serpentine belt too much slack which will allow the belt to slip and yes, the engine can overheat as a result.

Where is the belt retention er on a 99 grand am?

If its the 3.4L it has an automatic tensioner. look right under the alternator and there is a pulley. That pulley and arm is the tensioner. To release the tension, there is a bolt on the inside of the pulley, put a wrench on it and pull like you are trying to tighten the bolt. The arm is spring loaded and will pull up, releasing tension.
