Fan Belt Replacement

Diesel Fan Belt Replacement

Thanks To Dodgeram.org

1. Remove the belt by inserting the drive nose of a 3/8" ratchet into the square hole in the idler pulley. Use the ratchet to unload the idler tension from the belt by rotating the ratchet counterclockwise as viewed from the front of the engine. The best position for the ratchet is almost straight up in front of the alternator. When tension has been released from the belt, remove it from the engine.

2. Route the fan belt around the pulleys as shown in the diagram under the hood. Position the belt over the grooved pulleys first, with the slack at the water pump pulley.

3. Using a 3/8" ratchet wrench with the drive inserted into the hole on the tensioner, lift the tensioner and slip the drive belt around the tensioner pulley and water pump pulley.

NOTE: The belt tensioner is spring-loaded and must be pivoted away from the drive belt. Pivoting in the wrong direction can result in damage to the belt tensioner.

Non-A/C belt drive components:

1. WATER PUMP

2. ACCESSORY DRIVE BELT

3. AUTOMATIC BELT TENSIONER

4. 3/8" SQUARE BOLT

5. MOUNT BOLT

May I add that on the 2004 Dodge Diesel (2500 mine anyways) the belt tensioner has a 1/2" square hole, which a 1/2" breaker bar will work fine, and access from under the truck is easier. To remove and install the belt the tensioner should be removed and inspected, as it is all but impossible to R&R the belt with tensioner in place. This can be done with a 13mm box wrench. The greater the box offset the more difficult the task becomes To remove the tensioner from the engine compartment come up from the top. .

47,000 miles.

Reason for belt removal was that I had symptoms as followed.
When pressing the brake to the floor I felt a pulsating in the pedal (stopped or moving, so it wasn't warped rotors), also the power steering acted as low on fluid. Since both the brakes and power steering are enhanced by a Hydro Boost pump (no vacume to brakes), the belt was the most logical culprit.

I have the belt off and the alternator, and I can see your point, however, how big a deal is it to remove the tensioner and more importantly, how big a deal is it to replace it?????

And yes my tensioner also took a 1/2" drive.

You don't have to remove the belt tensioner to get the belt arround it. Take a 13mm gear wrench and loosen the mounting bolt a few turns. With the belt off you can inspect all the rollers and water pump for play. If you don't have a short 1/2" pull handle a 3/8" with a 3/8x1/2" adaptor may make it a bit easier.
