COOLING SYSTEM SERVICE WARNINGS

Warning
• Never remove the radiator 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 is cool. 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.

1. Measure the coolant temperature and specific gravity with a thermometer and a hydrometer.
Caution
• The engine has aluminium 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 effectiveness.
2. Determine the coolant protection by referring to
the graph shown.
• If the coolant protection is not proper, add
water or coolant.
