Engine Coolant Protection Inspection

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 cut down on 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.
