If engine coolant other than FL22 type is used, the engine coolant must be replaced earlier than the specified replacement interval indicated in the scheduled maintenance (page 8-3). WARNING Removing the Cooling System Cap: Removing the cooling system cap while the engine is running or hot is dangerous. This might lead to cooling system and engine damage and could result in serious injury from escaping hot coolant or steam. Turn off the engine and wait until it's cool. Even then, be very careful when removing the cap. Wrap a thick cloth around the cap and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes. When you're sure all the pressure is gone, press down on the cap ― still using a cloth ― turn the cap, and remove it. 1. Remove the cooling system cap. 2. Only when the engine is cool, loosen the radiator drain plug and drain the coolant into a suitable container. Properly dispose of the used coolant. 3. With the drain plug loose but not fully removed, flush out the system with running water.
