Check engine coolant/anti-freeze protection every 12 months (before the onset of freezing weather, where applicable). If engine coolant/anti-freeze is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh engine coolant/anti-freeze.
Check the front of the radiator for any accumulation of bugs, leaves, etc. Clean the radiator by gently spraying water from a garden hose at the back of the core. Check the engine cooling system hoses for condition and tightness of connection. Inspect the entire system for leaks. Any hoses that show cuts or severe abrasion must be replaced.
At the intervals shown in the appropriate Maintenance schedules, the system should be drained, flushed, and refilled.
If the solution is dirty and contains a considerable amount of sediment, clean and flush with reliable cooling system cleaner. Follow with a thorough rinsing to remove all deposits and chemicals.
Used ethylene glycol-based engine coolant/anti-freeze is a regulated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for your community. Do not store ethylene glycolbased engine coolant/anti-freeze in open containers or allow it to remain in puddles on the ground. Prevent ingestion by animals and children. If ingested by a child, contact a physician immediately. Clean up any ground spills immediately.
Use only the manufacturer's recommended engine coolant/anti-freeze, refer to Recommended Fluids, Lubricants, and Genuine Parts for correct engine coolant/ anti-freeze type.
This vehicle has not been designed for use with Propylene Glycol based engine coolant/anti-freeze. Use of Propylene Glycol base engine coolant/antifreeze is not recommended.
When adding engine coolant/anti-freeze, a minimum solution of 50% recommended HOAT ethylene glycol engine coolant/anti-freeze in water should be used. Use higher concentrations (not to exceed 70%) if temperatures below -34°F (-37°C) are anticipated. Use only high purity water such as distilled or deionized water when mixing the water/engine coolant (antifreeze) solution. The use of lower quality water will reduce the amount of corrosion protection in the engine cooling system.
Please note that it is the owner's responsibility to maintain the proper level of protection against freezing according to the temperatures occurring in the area where the vehicle is operated.
NOTE: Mixing engine coolant types will decrease the life of the engine coolant/anti-freeze and will require more frequent engine coolant/anti-freeze changes.
The cap must be fully tightened to prevent loss of coolant, and to insure that coolant will return to the radiator from the coolant reserve tank. The cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.
Check the engine coolant level at least once a month or more often in hot weather. Check the level when the engine is at normal operating temperature. Check the engine coolant level only in the coolant recovery bottle. The engine coolant level must be between the FULL and the ADD mark on the bottle. See your authorized dealer if the engine coolant level drops quickly.
NOTE: When the vehicle is stopped after a few miles of operation, you may observe vapor coming from the front of the engine compartment. This is normally a result of moisture from rain, snow, or high humidity accumulating on the radiator and being vaporized when the thermostat opens, allowing hot coolant to enter the radiator.
If an examination of your engine compartment shows no evidence of radiator or hose leaks, the vehicle may be safely driven. The vapor will soon dissipate.
