Tools you will need
- Flat blade screwdriver
- 15mm socket
- Ratchet
Parts and supplies
- A/C compressor belt
Steps
Clear the intake and main belt
Remove the intake assembly and move the radiator hose from the work area. Note the serpentine-belt routing, release its tensioner with the proper drive, and remove the belt.
Remove the A/C belt
Remove the lower protective plate fasteners and set the plate aside. Release the A/C belt tensioner carefully, then remove the old belt from the compressor and crank pulleys.
Install both belts and reassemble
Route the new A/C belt over the correct pulleys and allow the tensioner to take up slack. Reinstall the main serpentine belt using its diagram, then refit the intake, hose, and lower plate.
Verify belt routing
Check that both belts sit centered in every pulley groove and that no hose or wire touches them. Start the engine briefly and listen for squeal or rubbing before driving.
Check your vehicle’s repair manual for exact specifications and fit.
