MAINTENANCE

Engine Coolant

Park the vehicle on level ground. Check the reserve tank and the coolant level in the
radiator. We recommend Acura Long Life Antifreeze/Coolant Type 2.
Checking the Reserve Tank
1. Check the amount of coolant in the reserve tank.
2. If the coolant level is below the MIN mark, add
the specified coolant until it reaches the MAX
mark.
3. Inspect the cooling system for leaks.
NOTICE
For vehicles used in temperatures below -31°F (-35°C), change the coolant from the
standard 50:50 antifreeze:water mix to one with added antifreeze. Consult a dealer
for more information.
Adding Coolant
1. Make sure the engine and radiator are cool.
2. Remove the engine compartment cover (see
page 133).
3. Turn the radiator cap counterclockwise and
relieve any pressure in the coolant system. Do
not push the cap down when turning.
4. Push and turn the cap counterclockwise until
you can remove it.
5. The coolant level should be up to the base of the
filler neck. Add coolant if it is low.
6. Put the radiator cap back on, and tighten it fully.
7. Pour coolant into the reserve tank until it
reaches the MAX mark. Put the cap back on the
reserve tank.
WARNING
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.
NOTICE
Pour the fluid slowly and carefully so you do not spill any. Clean up any spills
immediately; they can damage components in the engine compartment.
