Where is the thermostat on your 98 Acura rl?

On a 1998 Acura RL, the thermostat is located in the engine compartment, specifically at the engine's coolant outlet. To access it, you'll typically need to remove the upper radiator hose, which connects to the thermostat housing. The thermostat itself is housed within this unit, secured by bolts. Make sure to let the engine cool before attempting to replace it to avoid burns.
