ENGINE COOLANT

Checking engine coolant

The concentration and level of engine coolant should be checked at the

intervals listed in the scheduled maintenance information. The coolant

concentration should be maintained at 50/50 coolant and distilled water.

Coolant concentration testing is possible with a hydrometer or antifreeze

tester. The level of coolant should be maintained at the FULL COLD

level or within the COLD FILL RANGE in the coolant reservoir. If the

level falls below, add coolant per the instructions in the Adding engine

coolant section.

Your vehicle was factory-filled with a 50/50 engine coolant and water

concentration. If the concentration of coolant falls below 40% or above

60%, the engine parts could become damaged or not work properly. A

50/50 mixture of coolant and water provides the following:

• Improved freeze protection

• Improved boiling protection

• Protection against rust and other forms of corrosion

• Enables calibrated gauges to work properly
