Where is the thermostat located on a 99 acura tl?

On a 1999 Acura TL, the thermostat is located on the engine block near the water pump. To access it, you typically need to remove the upper radiator hose and the thermostat housing, which is usually bolted down. This area is near the front of the engine, making it somewhat accessible for maintenance. Always ensure the engine is cool before attempting any work on the cooling system.
