Question about 2003 Pontiac Sunfire
I recommend you get the Haynes repair manual on your vehicle for all of these. That will tell you not only where they are but how to check, adjust or replace them if needed. The timing belt is normally located on the front of the motor under a cover, the vales are located under the valve covers on each side of the motor, or top of the motor in a 4 cylinder, and the temp sensor location will depend on which engine you actually have installed in the vehicle.
