How to install a serpentine belt on a 1994 mercury grand marquis it seems that i can get a 3/8 or 1/2in ratchet to move tensioner
It is sometimes pretty tough getting it to move.
Make sure you are Rotating it the correct way.
Do you have a Breaker Bar or a Serpentine Belt Tensioner Tool. Stores like Harbor Freight and even some Auto Parts Stores have these. Some of the auto parts stores have these for rent (for free with a refundable deposit).
I like and use weekly the Serpentine Tool from Harbor Freight (Item #66344-0VGA- $20). It is narrow enough to fit in most tight spots. The main bar has a 3/8-in fitting, and the extension bar can connect to this with a 1/2-in fitting.
The idea is to have more leverage. The Ratchet and/or Wrench sometimes does not provide that leverage needed.
When installing follow the below guidelines. DO NOT try to put the Belt on the Tensioner last.
Standard Rules to Removal the Serpentine Belt with an Automatic Tensioner:
1. Find the Tensioner(s).
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating the Tensioner Pulley/Arm - moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.
4. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.
Standard Rules for Installing the Serpentine Belt with an Automatic Tensioner:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them.
