Solution

1. Preparation

Gather tools and parts needed for the replacement.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Remove Engine Covers

Remove any plastic engine covers or components obstructing access to the timing belt.
Use a socket set to remove bolts and carefully lift off the covers.

3. Remove Accessory Belts

Use a wrench to release tension on the serpentine belt tensioner.
Slide the serpentine belt off the pulleys and set it aside.

4. Drain Engine Coolant

Locate the drain plug on the radiator and drain the coolant into a suitable container.
Remove the upper radiator hose connected to the engine to gain access to the timing belt cover.

5. Remove Timing Belt Cover

Unscrew the bolts securing the timing belt cover.
Gently pry off the cover to expose the timing belt assembly.

6. Align Timing Marks

Rotate the crankshaft using a socket and ratchet until the timing marks on the crankshaft and camshaft gears align according to the service manual specifications.
Ensure the engine is at top dead center (TDC) on cylinder one.

7. Remove Timing Belt

Loosen the tensioner bolt and remove the timing belt from the pulleys.
Carefully slide the old timing belt off the camshaft and crankshaft gears.

8. Install New Timing Belt

Place the new timing belt over the gears, ensuring it is properly seated and aligned with the timing marks.
Tighten the tensioner bolt to the specified torque in the service manual.

9. Reassemble Components

Reinstall the timing belt cover, ensuring all bolts are tightened to the recommended torque.
Reconnect the upper radiator hose and refill the coolant.
Reinstall the serpentine belt and any engine covers that were removed.

10. Final Checks

Reconnect the negative battery terminal.
Start the engine and check for any unusual noises or leaks.
