Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Remove any accessories obstructing access to the timing belt (e.g., engine covers, serpentine belt).

2. Remove the Timing Belt Cover

Using a socket set, remove the bolts securing the timing belt cover.
Gently pry off the cover to avoid damaging it.

3. Align Timing Marks

Rotate the crankshaft to align the timing marks on the crankshaft and camshaft gears. Use a socket on the crankshaft pulley bolt and turn clockwise.
Ensure the engine is at Top Dead Center (TDC) on the compression stroke for cylinder one.

4. Remove the Old Timing Belt

Loosen the tensioner pulley bolt using a wrench.
Slide the tensioner away from the belt to relieve tension.
Carefully remove the old timing belt from the camshaft and crankshaft gears.

5. Install the New Timing Belt

Position the new timing belt over the crankshaft gear, then over the camshaft gears, ensuring proper alignment with the timing marks.
Reinstall the tensioner pulley and adjust to ensure proper tension on the new belt.

6. Reassemble Components

Reinstall the timing belt cover and secure it with bolts.
Reinstall any accessories that were removed, such as the serpentine belt and engine covers.

7. Final Checks

Reconnect the negative battery terminal.
Start the engine and listen for any unusual noises.
Check for leaks around the timing cover and ensure the engine runs smoothly.
