Overheating
If the temperature gauge needle is at the H mark, the engine suddenly loses power, or steam or spray comes out from under the hatch, your engine is overheating.
Immediately park the vehicle in a safe place. Turn off all accessories and turn on the hazard warning lights. Change the gear position to (P).
If no steam or spray is present: Keep the power system on and open the hatch.
If steam or spray is present: Turn off the power system and wait until it subsides. Then, open the hatch.
Check that the cooling fan is operating and turn the power system off once the temperature gauge needle comes down. If the cooling fan is not operating, immediately turn the power system off.
Once the engine has cooled down, inspect the coolant level and check the cooling system components for leaks. If the coolant level in the reserve tank is low, or no coolant is in the tank, check that the radiator is cool. Cover the reserve tank cap with a heavy cloth and open the cap. Add coolant until it reaches the MAX mark, and put the cap back on.
Once the engine has cooled sufficiently, turn the power system on and check the temperature gauge. If the temperature needle has gone down, resume driving. If it has not gone down, contact an authorized Acura NSX dealer for repairs.
Steam and spray from an overheated engine can seriously scald you.
Do not open the hatch if steam is coming out.
Removing the radiator cap while the engine is hot can cause the coolant to spray out, seriously scalding you.
Always let the engine and radiator cool down before removing the radiator cap.
