Steps
- Disconnect the battery
Switch the ignition off and disconnect the negative battery cable. Keep it isolated from the terminal while working around the belt drive.
- Move the alternator belt aside
Loosen the alternator adjuster fastener and pivot nut, then back off the adjuster. Move the alternator inward enough to remove the belt and set it aside if it remains in serviceable condition.
- Remove the A/C compressor belt
Remove the passenger-side splash shield fasteners to reach the tensioner. Loosen the tensioner lock bolt, back off its adjuster, and slip the old compressor belt off the pulleys.
- Fit and tension the compressor belt
Route the replacement belt over the compressor and tensioner pulleys according to the belt path. Turn the adjuster until belt deflection matches the vehicle specification, then secure the tensioner lock bolt.
- Restore the alternator belt and shield
Route the alternator belt correctly and adjust its tension to the vehicle specification. Tighten the adjuster and pivot fasteners, refit the splash shield, and confirm both belts sit in every pulley groove.
- Reconnect the battery and inspect
Reconnect the negative cable and start the engine briefly. Listen for belt squeal, watch for belt tracking problems from a safe distance, and shut the engine off immediately if either belt walks or rubs.
Check your vehicle’s repair manual for exact specifications and fit.
