Remove the old, damaged idler pulley and replace it with a new one.
Usualy the tensioner or idler pulley is spring loaded and can be pulled backwards allowing enough slack for the belt to slip on easily On a 1992-1996 Beretta/Corsica, the upper engine mount needs to be removed in order to remove/replace the serpentine belt. Replace the belt, and reinstall the engine mount.
I believe there is an idler pulley which keeps the belt tight on the 4.0. If you are experiencing slop or looseness, I suggest you look at replacing the belt or maybe the idler is stuck or broken. I had to replace an idler in a Wrangler once.
take off the belt and there is one bolt take it off and put a new one one.
Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.
You haav to loosen the idler pulley lock nut and turn the adjusting bolt to let the tension off the old one. Put the new one on and tighten the adjusting bolt until the belt is tight and then tighten the idler pulley lock nut.
The timing marks, on your 1992 Toyota, are located on the main engine pulley. The timing marks can be found around the perimeter of the pulley.
On 302 5.0L models, the engine mounts need to be unbolted and the engine lifted up from the frame. I lifted by the crank pulley with a piece of wood in between the jack and pulley. The pan can be dropped partially to unbolt the oil pickup/pump from the engine and then the pan can be dropped.
It is mounted just above the crankshaft pulley on the front of the engine.It is mounted just above the crankshaft pulley on the front of the engine.
change the idler pulley
Yes, all cars do. It is the crankshaft pulley assembly...the biggest pulley, typically, at the very bottom of the engine.
No,the engine is designed to be no interference.You can turn the crank or cam without damage to get it in time.
should be a single bolt in the center of the tensioner probly 15mm
