While specific diagrams can vary slightly based on engine type (e.g., 1.8L or 2.0L), the general routing remains consistent. It is essential to ensure that the belt is correctly aligned with all pulleys to avoid slippage or damage.

Replacing the Serpentine Belt

Replacing the serpentine belt involves several steps that can be performed with basic tools. Here’s how to do it:

1. Gather Necessary Tools:

- New serpentine belt

- Metric socket set (12 mm and 14 mm sockets)

- Ratchet wrench

2. Prepare the Vehicle:

- Disconnect the negative battery terminal to ensure safety.

- Raise the vehicle if necessary for better access.

3. Loosen the Alternator:

- Locate the alternator and loosen its mounting bolts using the appropriate socket sizes.

- You do not need to remove these bolts completely; just loosen them enough to allow movement.

4. Remove the Old Belt:

- With the alternator loosened, you can now slide it down to relieve tension on the serpentine belt.

- Carefully remove the old belt from all pulleys.

5. Install the New Belt:

- Route the new serpentine belt according to the diagram.

- Ensure that it sits properly in all grooves of the pulleys.

6. Re-tension and Secure:

- Push the alternator back up into position and tighten its bolts securely.

- Reconnect the negative battery terminal.

7. Test:

- Start your vehicle and observe the belt’s operation to ensure there are no unusual noises or misalignments.
