Locate the serpentine belt tensioner and relieve tension on the belt.
Remove the old serpentine belt, taking note of the routing.
Install the new serpentine belt according to the routing diagram located in the engine bay.
Reapply tension and ensure the belt is properly seated on all pulleys.

4. Inspect Exhaust System

Tools Required: Jack and jack stands, exhaust pipe wrench.
Raise the vehicle using a jack and support it with jack stands.
Inspect the exhaust system from the manifold to the tailpipe for any signs of leaks or loose connections.
Tighten or replace any loose clamps or damaged sections of the exhaust.

5. Test Intake Manifold

Tools Required: Torque wrench, intake manifold gasket.
