Scheme 7
| WARNING | Never remove the cooling system cap or loosen the radiator drain plug while the engine is running, or when the engine and radiator are hot. Scalding coolant and steam may shoot out and cause serious injury. It may also damage the engine and cooling system. Turn off the engine and wait until it has cooled. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes. When you are sure all the pressure is gone, press down on the cap using the cloth, turn it, and remove it. |

- Verify that the coolant level in the coolant reservoir is between the F and L marks. If the engine coolant level is below L, remove the cooling system cap and add coolant. (See «ENGINE COOLANT REPLACEMENT»(ref-193833-S33923677642005092600000) .)
Scheme 10
- Measure the coolant temperature and specific gravity with a thermometer and a hydrometer. CAUTION: The engine has aluminum parts that can be damaged by alcohol or methanol antifreeze. Do not use alcohol or methanol in the cooling system. Use only ethylene-glycol-based coolant. Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will reduce the coolant's effectiveness.
- Determine the coolant protection by referring to the graph (Scheme 10) If the coolant protection is not proper, add water or coolant.
