How to Replace a Drive Belt on an Isuzu Rodeo

by Grace Mclain

The Isuzu Rodeo comes with a serpentine belt on the front of the engine that operates all of the engine accessories. The belt operates the alternator, air conditioner, water pump and the power steering. The belt is configured around each accessory shown by the serpentine belt routing diagram. Replace the belt if it appears worn or frayed. If the belt breaks, all of the accessories on the engine will stop working.

1

Open the hood of your Isuzu Rodeo and prop it up with the locking rod attachment.

2

Examine the serpentine belt routing diagram on the left-hand side of the hood locking latch on top of the fan shroud. You will need this diagram to properly configure the new belt around the accessory pulleys.

3

Locate the belt tensioner device on the front center of the engine below the alternator. The tensioner device has a roller pulley on one end that is mounted to the tensioner arm by a small bolt. Use the head of the bolt to turn the tensioner device.

4

Turn the tensioner device by the bolt head in the center of the roller pulley counterclockwise with a breaker bar and a socket. Reach down and slide the belt out from around the roller pulley. Release the tensioner device.

5

Remove the serpentine belt from each accessory pulley. Pull the belt around the fan blades and out of the engine area. Match the old belt to the new belt to ensure that the new belt is the correct length.

6

Slide the new belt around the fan blades and around the accessory pulleys by following the routing directions on the diagram.

7

Turn the tensioner device by the roller pulley bolt head counterclockwise with the breaker bar and socket. Slide the new belt around the roller pulley and release the tensioner. Remove the breaker bar and socket. Inspect the new belt to make sure that it is centered around the roller pulley and that the belt is seated inside of each accessory pulley.

8

Crank the Isuzu Rodeo for 10 seconds so that the new belt can completely seat onto the inside of each accessory pulley. Then turn the engine off and shut the hood.

Tip

  • If the routing diagram for the serpentine belt cannot be located anywhere under the hood, draw out a diagram before starting the belt replacement process.

Warning

  • Take the keys out of the vehicle's ignition before starting any work under the hood. This will prevent someone from accidentally cranking the engine.
