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

Caution

• Use engine coolant at a concentration that meets the environmental conditions in which the vehicle is driven, otherwise engine damage could occur.

• The engine has aluminum parts and must be protected by an ethylene-glycol-based coolant to prevent corrosion and freezing.

• Do not use coolants containing Alcohol, Methanol, Borate or Silicate. These coolants could damage the cooling system.

• Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will cut down on the coolant’s effectiveness.

• Engine coolant damages paint. If engine coolant does get on a painted surface, rinse it off quickly.

Note

• If the “FL22” mark is shown on or near the cooling system cap, use Mazda Genuine FL22 engine coolant.

• FL22 type engine coolant is shipped as a diluted solution. Use the solution as is when replacing coolant.

2.Determine the engine coolant protection level by referring to the graph shown in the figure.

• If the engine coolant protection level is not correct, add water or engine coolant.
