Solution

1. Preparation

Tools Required: Socket set, torque wrench, timing belt tool kit, jack and jack stands, screwdriver set, engine oil, and a clean cloth.
Safety Warnings: Disconnect the battery to prevent electrical shorts.

2. Remove Components

Elevate the vehicle using a jack and secure it on jack stands.
Remove the engine cover (if applicable) by unscrewing the bolts.
Detach any components obstructing access to the timing belt, such as the air intake duct, radiator fan, and serpentine belt.
Drain the engine coolant by removing the radiator drain plug.

3. Access the Timing Belt

Remove the crankshaft pulley by loosening the bolt (may require a special tool to hold the crankshaft).
Remove the timing belt cover by unscrewing the bolts securing it.

4. Replace the Timing Belt

Align the timing marks on the crankshaft and camshaft sprockets to ensure correct timing.
Loosen the tensioner pulley and remove the old timing belt.
Compare the old timing belt with the new one to ensure correct length and tooth count.
Install the new timing belt by routing it around the camshaft and crankshaft sprockets, ensuring it is tight against the tensioner.
Re-tension the timing belt according to manufacturer specifications.

5. Reassemble Components

Reinstall the timing belt cover and crankshaft pulley, tightening bolts to specified torque values.
Reattach the components removed earlier (radiator fan, serpentine belt, air intake).
Refill the engine coolant and ensure there are no leaks.

6. Final Checks

Reconnect the battery.
Start the engine and allow it to idle for a few minutes while checking for abnormal noises or leaks.
