The 1998 Dodge Dakota tensioner pulley will be the top pulley on the left-hand side of the engine. The tensioner pulley will be able to slide back and forth.
Facing the engine the tensioner will be on left side of engine. There is an idler pulley that looks like the tensioner. The idler will have a smooth surface but the tensioner will have grooves on the pulley & should below the idler. If the tensioner is making noise etc it is prob just the tensioner pulley (grooved one) & you can get just the pulley. Big savings.
the idler pulley.
The Serpentine Belt needs to be tightend with the tensioner pulley (Idler Pulley)
There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.
I don't believe there is an idler pulley on that model, just a tensioner pulley
98% of the time it is the tensioner or idler pulley. With engine off take WD 40 with that little plastic tube & spray the back side of either one, idler or tensioner pulley, not both. Take a drive & if you still hear the belt noise then it is the pulley you didn't spray. The tensioer pulley is replacable on most dakotas. When you remove the belt the tensioner should have strong spring action & move smoothly. If it does then just replace the pulley. Some places will try to sell you the whole tensioner.
Replace the tensioner assembly as one piece.
The idler tensioner pulley on your 1999 Ford F3 50 pickup truck is held in place with a single retaining bolt. The retaining bolt will go through the middle of the pulley. Tighten the retaining bolt to install the tensioner pulley.
I assume you mean the idler pulley on your timing assembly, if this is the case then the belt is too tight loosen tensioner pulley. if you mean the automatic tensioner pulley for your alternator and A/C and the like, the you probably need a new tensioner] Good Luck
You don't. The serpentine belt tension is automatically maintained by the tensioner pulley, which is an idler pulley located on the passenger side of the system and looks like it doesn't drive anything. If the belt tension is incorrect, the tensioner pulley must be replaced. If the question meant 'how to release tension from the belt' (for removal, etc.), this is done by applying the correct size socket wrench to the tensioner pulley's center nut and rocking the pulley away from the belt.
If your car has a serpentine belt it will have a tensioner pulley. A tensioner pulley is easy to spot. All of your bolt on accessories i.e. water pump, alternator, a/c compressor etc. will have a pulley to run each one. There will be 2 other types of pulleys, a idler pulley and a tensioner. The idler pulley will be a single stationary pulley with a bolt going through the middle and the tensioner pulley will be on a spring loaded piviot.
Belt tensioner? Idler pulley?
