Yes, if the belt tension is not tight enough it won't spin the radiator fan due to slippage. Replace the tensioner pulley.
this should be spring loaded self adjusting if not tensioner is bad.
The early 4.7 engine in the grand cherokee,dakotas,and rams have had problems with cylinders on the rear left of the engine,starting with a knocking then overheating and seizing .
Failed water pump bearing.
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
With two special tools, a slim 36mm wrench and a spanner to hold the pulley.
Loosen the tensioner pulley. Put the belt around the alternator pulley and the tensioner pulley. Move the tensioner pulley to the right until the belt is tight. Tighten the tensioner pulley.
Put a ratchet on the tensioner pulley bolt... set your ratchet on "loosen" turn the tensioner pulley and assembly upword... hold it there and remove the belt... DO NOT LET GO OF THE RATCHET AFTER YOU REMOVE THE BELT slowly let the tensioner pulley move back to a resting position...
it has a manual tensioner
On a 1994 Jeep Grand Cherokee with a 5.2 V8 engine, the serpentine belt tensioner is located on the front of the engine, near the center. It is typically positioned above the crankshaft pulley and to the right of the alternator. The tensioner is a pulley mounted on a spring-loaded arm, which maintains tension on the serpentine belt. To adjust or replace it, you may need to use a wrench to relieve tension before removing the belt.
Should have an automatic belt tensioner -perhaps it is defective I don't think there is a belt tensioner. Belt tension is adjusted at the power steering pump bracket and idler pulley assembly.
To tighten the tensioner pulley on a 2001 Suzuki Grand Vitara 4WD, first, locate the tensioner pulley, which is typically part of the serpentine belt system. Use a ratchet and socket to rotate the tensioner pulley counterclockwise, relieving tension on the belt. Once the belt is properly positioned, slowly release the tensioner to apply tension to the belt. Ensure that the belt is aligned correctly on all pulleys before starting the engine.
Yes, on a 3.3 or 3.8 the serpentine belt pulley does come off the tensioner arm but the bolt is left thread not right handed.
this should be spring loaded self adjusting if not tensioner is bad.
When the tensioner pulley is frozen and u need to change the belt the only possible thing you can do is cut the old belt and replace the belt tensioner pulley, theres no other possible method.
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.
What device is it attached to?
its a pulley fan, it never goes bad
