Tools you will need
- 14mm Socket
- 10mm Socket
- Ratchet
- 1/2 Inch Breaker Bar
Parts and supplies
- Serpentine drive belt matching the vehicle configuration
Steps
Remove the engine cover and note routing
Remove the engine cover fasteners and lift the cover away. Photograph the belt path or follow the routing diagram before releasing tension so the replacement follows the same route.
Remove the old belt
Fit the correct socket and breaker bar to the tensioner and rotate it to create slack. Slip the belt off the alternator, release the tensioner slowly, and remove the belt from the remaining pulleys.
Route the replacement belt
Loop the new belt around the crankshaft, idlers, water pump, and air conditioning pulley according to the diagram. Rotate the tensioner, place the belt over the alternator, then release the tensioner gradually.
Check belt tracking
Inspect each pulley to confirm the belt ribs sit in the grooves and the belt is not twisted. Reinstall the engine cover, start the engine briefly, and check for squealing or belt movement.
Check your vehicle’s repair manual for exact specifications and fit.
