Engine Coolant Protection Inspection
WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
- Measure the engine 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 engine coolant.
- Use only soft (demineralized) water in the engine coolant mixture. Water that contains minerals will reduce the engine coolant's effectiveness.
- Determine the engine coolant protection by referring to the graph shown.
- If the engine coolant protection is not proper, add water or engine coolant.
