ENGINE COOLANT PROTECTION INSPECTION

BHE011215001W03

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.
