- Flat-head screwdriver
- 10mm socket wrench and ratchet
Parts Needed:
- Replacement serpentine belt
- Replacement timing belt
- Tensioner pulley assembly (if needed)
Instructions:
1. Disconnect Negative Battery Cable: Start by disconnecting the negative terminal on the battery. This is to prevent any electrical accidents while you're working on the belts.
2. Remove the Serpentine Belt:
- Locate the serpentine belt. It's usually on the front of the engine, running around the water pump, alternator, and air conditioning compressor.
- Use the 10mm socket and ratchet to loosen the tensioner pulley.
- Once the tension is released, slip the belt off the pulleys and remove it.
3. Remove the Timing Belt:
- Locate the timing belt cover at the front of the engine and remove the bolts holding it in place.
- Remove any remaining parts or covers blocking access to the timing belt.
- Align the timing marks on the camshaft and crankshaft pulleys.
- Loosen the tensioner pulley and remove the old timing belt.
4. Replace the Timing Belt:
- Install the new timing belt by aligning the timing marks and slipping the belt over the pulleys.
- Tighten the tensioner pulley to the specified torque (refer to the vehicle manual).
5. Replace the Serpentine Belt:
- Replace the serpentine belt by slipping it over the pulleys and adjusting the tensioner pulley.
6. Reconnect Battery Cable:
- Reconnect the negative terminal of the battery.
7. Test the Belts:
- Start the engine and let it run for a few minutes. Make sure the belts are running smoothly and adjust the tension if needed.
*Note: If your vehicle has a lot of miles or the tensioner pulley is damaged, it's recommended to replace the tensioner pulley along with the belts.*
Precautions:
- Follow all safety precautions when working with electrical components.
- Refer to the vehicle's repair manual for specific instructions and torque specifications for your particular model.
- If you're unsure about any of the steps, it's best to seek help from a professional mechanic.
