Coolant: Testing and Inspection
RADIATOR COOLANT LEVEL CHECKCheck engine coolant level in the radiator coolant recovery reservoir at least once a month.
With cold engine, the level must be maintained at or above the FULL COLD mark. If coolant level in the radiator coolant recovery reservoir is below specified levels, a 50/50 mixture of Premium Cooling System Fluid and water should be added to the radiator coolant recovery reservoir to the specified level.
If the radiator coolant recovery reservoir is low, add the specified 50/50 coolant mixture to the radiator coolant recovery reservoir. Check the coolant level again after one or two occasions of vehicle use.
