Raise the vehicle using a jack and secure it with jack stands.

2. Remove Components

Remove the Engine Cover:
- Use a socket set to remove the bolts securing the engine cover.
- Lift off the engine cover and set it aside.
Remove the Accessory Belts:
- Use a wrench to relieve tension on the serpentine belt tensioner.
- Remove the serpentine belt from the pulleys and set it aside.
Remove Timing Belt Covers:
- Remove any bolts securing the upper and lower timing belt covers.
- Carefully pry off the covers and set them aside.

3. Remove the Old Timing Belt

Align the Timing Marks:
- Rotate the crankshaft to align the timing marks on the crankshaft and camshaft sprockets.
Remove Timing Belt Tensioner:
- Loosen the bolts on the timing belt tensioner using a socket set.
- Remove the tensioner and keep it for inspection.
Remove Timing Belt:
- Carefully slide the timing belt off the camshaft and crankshaft sprockets.

4. Install New Timing Belt
