Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before proceeding.

2. Remove Engine Covers

Use a socket set to remove the screws/bolts securing the engine covers.
Carefully lift off the covers to expose the timing belt.

3. Inspect Components

Timing Belt: Check for signs of wear, cracking, or fraying.
Tensioner & Pulleys: Inspect the tensioner for proper operation and replace if it is faulty. Check pulleys for any signs of play or damage.
Accessories: Check auxiliary components (water pump, alternator) driven by the timing belt for proper function.

4. Replace Timing Belt (if necessary)

Removal:
- Rotate the crankshaft to align timing marks.
- Loosen the tensioner to relieve tension on the belt.
- Remove the old timing belt from the camshaft and crankshaft pulleys.
Installation:
- Install the new timing belt, ensuring it aligns with timing marks.
- Re-tension the timing belt using the tension gauge to manufacturer specifications.

5. Reassemble and Test

Reattach engine covers securely.
Reconnect the negative battery terminal.
Start the engine and listen for any abnormal noises.
