The main fuse box is located under the hood on the driver's side near the fender. There is also an interior fuse box located under the dashboard on the passenger side.

The 2003 Pontiac Grand Prix typically uses Dex-Cool antifreeze. It is important to use the correct type to prevent damage to the cooling system. Always check the owner's manual for confirmation.
Overheating can be caused by several issues, including a faulty thermostat, a leaking radiator, or a failing water pump. Check for coolant leaks, ensure the radiator fan is operational, and inspect the thermostat for proper function.
To replace the serpentine belt, locate the belt tensioner and use a wrench to rotate it, relieving tension on the belt. Remove the old belt and install the new one according to the belt-routing diagram. Release the tensioner to secure the belt in place.
If the check engine light comes on, use an OBD-II scanner to retrieve the diagnostic trouble codes. This will help identify the issue. Common problems include a loose gas cap, faulty oxygen sensors, or ignition system issues.
