Engine Coolant

Specified coolant:
Acura Long Life Antifreeze/Coolant Type 2

This coolant is premixed with 50% antifreeze and 50% water. Do not add any straight antifreeze or water.

We recommend you check the engine coolant level every time you refuel. Check the reserve tank first. If it is completely empty, also check the coolant level in the radiator. Add the engine coolant accordingly.

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.

Detail

NOTICE
Genuine Acura engine coolant is a 50/50 mixture of antifreeze and water that can withstand freezing at temperatures as low as about −31°F (−35°C). If your vehicle is consistently subjected to temperatures below this, the concentration of antifreeze in the coolant should be increased. Consult a dealer for details.


If Acura antifreeze/coolant is not available, you may use another major brand of non-silicate coolant as a temporary replacement. Check that it is a high quality coolant recommended for aluminum engines. Continued use of any non-Acura coolant can result in corrosion, causing the cooling system to malfunction or fail. Have the cooling system flushed and refilled with Acura antifreeze/coolant as soon as possible.

Do not add rust inhibitors or other additives to your vehicle’s cooling system. They may not be compatible with the coolant or with the engine components.

Reserve Tank

  1. Make sure the engine and radiator are cool.
  2. Check the amount of coolant in the reserve tank.
    • 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.
 

Radiator

  1. Make sure the engine and radiator are cool.
  2. Turn the radiator cap 1/8 turn counter-clockwise and relieve any pressure in the cooling system.
  3. Push down and turn the radiator cap counter-clockwise 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.

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.
