Where is the thermostat located on a 2003 Pontiac Grand Am?

The thermostat on a 2003 Pontiac Grand Am is located on the engine, typically at the lower portion of the engine near the water pump. However, the exact location can vary slightly depending on the engine type (2.2L or 3.4L).

To be certain, you'll need to consult a repair manual specific to your vehicle's engine. A repair manual (either a physical book or a digital version) will have diagrams showing the exact location and will provide detailed instructions for replacement. You can find these manuals online or at auto parts stores.

Attempting to locate it without a diagram could lead to wasted time and potential for misidentification of other components.
