what size engine
lokks to be on the lower right side of engine
the tensioner assembly is bolted to the side of the engine block. the spring is contained within the assembly. View my BIO for access to my Saturn help site. there is a picture of the assembly under the Serpentine belt folder
The serpentine belt you can look at the diagram in your engine compartment for actual routing. The tensioner mounts to the left side of the engine. You need to unbolt the whole assembly. Actually, the belt can be loosened by tightening the bolt of the tensioner pulley. When fully tightened, the pulley will act as a swivel.
After you have released the tension from the belt, remove the 2 obvious bolts that hold it to the engine block.
The weep (overflow) hole cannot be closed on a 1998 Pontiac Grand Am 2.4 liter. This hole is there so that the engine can let off pressure when things get a little too warm. It keeps the engine from overheating.
Automatic belt tensioner - if not enough pressure replace tensioner Belt has streched too big, and the Automatic belt tensioner is at its limit. The tentioner is how yo remove the belt, so you should feel its tention with your wrench.
The tensioner belt is interchangable as both vehicles use the same engine, the GM 3800
How to replace the tensioner assembly depends on which engine your car has. If it is the 2.5L 4cylinder engine: 1. The tensioner assembly covers a coolant opening in the block, so you need to drain the coolant to point lower than the bottom of the tensioner assembly. 2. Release the tension on the serpentine belt and move the belt out of the way. 3. The tensioner assembly also is the mounting point for the power steering pump. So to change the tensioner assembly first remove the power steering pump. Be careful to avoid power steering fluid leakage. 4. With the power steering pump off, the tensioner assembly is held onto the block with three screws, remove them. 5. At this point the tensioner assembly should simply pull off. It may be stuck to the block with rtv sealant. Install the new tensioner: 1. Clean the old sealant off of the block. Be sure to have an adequate bead of rtv on the block or the tensioner to seal against coolant leaks. The last time I replaced one of these there was no mounting gasket, it was all done with just rtv sealant. 2. Mount the new tensioner and tighten the bolts. 3. Reattach the power steering pump. Check the fluid level, refill if necessary. 4. Reinstall the serpentine belt. 5. Top off coolant as necessary, check for leaks. If your car has the 2.8L V6: 1. Release the tension and remove the serpentine belt. 2. The tensioner assembly is held on by one bolt in the middle of the fixed end. Remove the bolt. 3. Install the new tensioner assembly. be sure it is in the correct rotation. Tighten the bolt. 4. Put the serpentine belt back on. You are done.
