Detach the serpentine belt using a ratchet and appropriate socket to release tension.
Remove any components such as the alternator, power steering pump, or water pump that may hinder access to the timing belt.
Label and store bolts and components safely.

4. Replace Timing Belt

Use a timing belt tensioner tool to relieve tension on the old timing belt.
Remove the old timing belt carefully, ensuring not to disturb the timing marks on the camshaft and crankshaft.
Align the new timing belt according to the timing marks and install it, ensuring proper tension is applied.

5. Reassemble Components

Reinstall any removed accessory components, ensuring all bolts are torqued to the manufacturer's specifications.
Reattach the serpentine belt and double-check the routing before tightening.
Replace any engine covers removed earlier, ensuring all bolts are secure.
