COOLING SYSTEM SERVICE WARNINGS

WARNING:
Remove and install all parts when the engine is cold, otherwise they can cause severe burns or serious
•
injury.
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.

ENGINE COOLANT LEVEL INSPECTION

WARNING:
Remove and install all parts when the engine is cold, otherwise they can cause severe burns or serious
•
injury.
Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a
•

1. Verify that the engine coolant level in the coolant reserve tank installed on the shroud panel is between
the L and F marks.
2. If the engine coolant level is below L, add engine coolant.

ENGINE COOLANT PROTECTION INSPECTION

1. 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.
2. Determine the coolant protection by referring to the graph shown.
If the coolant protection is not proper, add water or coolant.
