Engine Coolant

Engine Coolant

Park the vehicle on level ground. Check the reserve tank and the coolant level in the radiator. Use Acura Long Life Antifreeze/Coolant Type 2.

Checking the Reserve Tank

  1. Open the hood (see "Under the Hood"). 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. Turn the radiator cap counterclockwise and relieve any pressure in the coolant system. Do not push the cap down when turning.

  3. Push down and turn the radiator cap counterclockwise to remove it.

  4. The coolant level should be up to the base of the filler neck. Add coolant if it is low.

  5. Put the radiator cap back on, and tighten it fully.

  6. 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.
