Solution

1. Preparation

Tools Required: Socket set, torque wrench, screwdriver set, flashlight, timing belt tension gauge (if available).
Ensure the engine is cool before starting work.
Disconnect the battery to prevent any electrical issues during the inspection.

2. Remove Timing Cover

Remove any engine covers if present.
Use the socket set to remove bolts securing the timing cover.
Carefully pry off the timing cover to avoid damaging any gaskets.

3. Inspect Timing Belt

With the cover removed, visually inspect the timing belt for cracks, wear, or glazing.
Check for proper tension by pushing down on the belt at the midpoint between pulleys; it should not deflect more than 1/2 inch.
Look for signs of oil contamination, which can indicate a leaking seal.

4. Check Timing Marks Alignment

Rotate the crankshaft manually using a wrench until the timing mark on the crankshaft aligns with the mark on the engine block.
Verify that the camshaft timing marks are also aligned properly.
If marks are misaligned, further inspection or adjustment may be required.

5. Reassemble Components

Reinstall the timing cover, ensuring any gaskets are replaced if damaged.
Torque the cover bolts to the manufacturer's specifications (typically 7-10 ft-lbs).
Reconnect the battery.
