448 MAINTAINING YOUR VEHICLE When additional coolant is needed to maintain the proper level, add the recommended concentration of antifreeze and water to the coolant bottle. Do not overfill. NOTE: Failure to follow the antifreeze concentration and replacement recommendations, or failure to use antifreeze formulated to prevent corrosion of all cooling system metals, may result in radiator plugging, overheating, or cooling system leaks such as in core hole plugs. Recommended Engine Coolant Refer to Fluids, Lubricants and Genuine Parts for correct fluid type. CAUTION! • Mixing of coolants other than specified engine coolant, may result in engine damage. If a nonHOAT coolant is introduced into the cooling system in an emergency, it should be replaced with the specified coolant as soon as possible. • Do not use plain water alone or alcohol base engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the radiator engine coolant and may plug the radiator. • This vehicle has not been designed for use with Propylene Glycol based coolants. Use of Propylene Glycol based coolants is not recommended. WARNING! Never add coolant to the radiator when the engine is overheated. Do not loosen or remove pressure cap to cool an overheated engine. The coolant is under pressure and severe scalding could result.
