- Screwdrivers
- Timing belt replacement kit (belt, tensioner, water pump if necessary)
- Engine support bar
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting work.

2. Remove Engine Components

Remove the engine covers (if applicable) using a socket set.
Remove the serpentine belt by loosening the tensioner and sliding the belt off the pulleys.
Remove any components obstructing access to the timing belt, such as the alternator or air intake duct.

3. Align Timing Marks

Rotate the crankshaft to align the timing marks on the crankshaft and camshaft sprockets. Ensure the marks are perfectly aligned to avoid timing issues.

4. Remove the Old Timing Belt

Loosen the tensioner bolt and remove the timing belt from the camshaft and crankshaft sprockets.
Take note of the routing of the belt for proper installation of the new belt.

5. Install the New Timing Belt

Place the new timing belt onto the crankshaft and camshaft sprockets following the routing from the previous belt.
Ensure the belt is taut and properly seated in the timing gears.
Adjust the tensioner to ensure the correct tension on the belt and tighten the tensioner bolt to the manufacturer's specifications.

6. Reassemble Components

Reinstall any components removed for access to the timing belt.
Reattach the serpentine belt and ensure it is properly aligned on the pulleys.
