Engine Coolant Protection Inspection

ENGINE COOLANT PROTECTION

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 cut down the coolant effectiveness.

1. Measure the coolant temperature and specific gravity with a thermometer and a hydrometer.





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