How do you Change, Replace, or Install Broken 2000-2005 Buick LeSabre Serpentine Engine Belt Replacement

Fits Years: 2000, 2001, 2002, 2003, 2004, 2005

Tools required:

  • 15mm socket/ratchet

Step 1: Open the vehicle's hood.

Step 2: Loosen the 15mm tensioner bolt (1) located just below the alternator pulley.

Step 3: You can now pull the serpentine belt from the vehicle.

Step 4: Using the diagram provided under the hood, position the new serpentine belt as shown.

NOTE: The diagrams are usually posted near the radiator on vehicles. However, if your particular vehicle does not have the diagram decal, remember that the belt goes BENEATH the lower pulleys, up and around the upper pulley, and BENEATH the power steering pump pulley. We do recommend that you either use the manual for routing or an online diagram.

Step 5: Now that the belt is properly routed, tighten the 15mm tensioner bolt (1).

The belt should be taut, but not stretched!
