To tighten the serpentine belt on a 1995 Infiniti G20, first, locate the tensioner pulley. Use a wrench or a ratchet to rotate the tensioner arm counterclockwise, which will relieve tension on the belt. With the tension released, inspect the belt for proper alignment and condition, then position the belt back onto the pulleys. Slowly release the tensioner to apply tension to the belt, ensuring it's properly seated on all pulleys.
There is a small braket at the bottom of the engine that needs to be removed to slip the old belt off and put the new one on. Remove it or loosen one end so you can get the belt around it. One of the pulleys is a spring loaded idler/tensioner for the belt. Use a wrench on the center bolt of this pulley to remove enough tension to allow the belt to slip off. Save this pulley for last when you put the new belt on and repeat the same operation with the wrench. There should be a diagram in the engine compartment to show how the surpentine belt goes around all the pulleys. If not, note how the belt runs before removing it.
It is the route the belt follows around all the pulleys on the engine that belt is driving.
You have a bad bearing in one of the pulleys. Remove belt and spend all the pulleys by hand, they should be smooth and quiet.
Make a diagram of all the pulleys and draw the belt in. Locate the belt tensionor. Loosen it. Slide belt off of the pulleys. Look at your diagram and install the new belt. Tighten tensionor. There should be little play in the belt after being installed on the pulleys.
- cut off the old belt - buy a new belt - take off the two pulleys that have yellow brackets (one on each side) that restrict you to just put on the belt - put the belt on all the other pulleys - put the other two pulleys back on
Remove surpentine belt,then take out bolt that goes through tensioner to engine.
doesn't have a timing chain- has a surpentine belt
Replace belt and check all pulleys for wear or rough spot
Yes, the belt system has pulleys.
Sometimes the old belt leaves a residue in the grooves of the pulleys. Clean the grooves of all the pulleys with a wire brush, and reinstall the serpintine. You also might have a bad belt tensioner.
You can usually feel it bottom out as you are installing it. After the pulleys are installed, you can put the belt on and see if all pulleys are aligned.
