"How do you clean the throttle body on a 2000 Pontiac Gran Prix?"
On a 2005 Pontiac Grand Prix with a 3.8L GTP engine, the coolant temperature sensor is located near the front of the engine, typically on the engine block or intake manifold. It is usually positioned close to the thermostat housing, making it accessible for replacement or inspection. You may need to remove some components for better access, but it is generally found on the driver's side of the engine.
Find the leak and replace the hose/part that's leaking. It's a good time to flush your coolant system, too.
