Coolant: Testing and Inspection

ENGINE COOLANT LEVEL INSPECTION





1. Verify that the coolant level in the radiator reservoir is between the FULL and LOW marks.
2. Add coolant if necessary.

Note:
^ The distance between the FULL and LOW marks on the radiator reservoir represents 0.4 L (0.4 US qt., 0.4 Imp qt.).


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 on the coolant's 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.





3. If the coolant protection is not proper, add water or coolant as necessary.
