Maintenance and care NOTE:State or local regulations on volatile organic compounds may restrict the use of methanol, a common windshield washer antifreeze additive. Washer fluids containing non-methanol antifreeze agents should be used only if they provide cold weather protection without damaging the vehicle's paint finish, wiper blades or washer system. WARNING: Do not put washer fluid in the engine coolant reservoir. Washer fluid placed in the cooling system may harm engine and cooling system components. Checking and adding washer fluid for the liftgate Washer fluid for the liftgate is supplied by the same reservoir as the windshield. ENGINE COOLANT Checking engine coolant The concentration and level of engine coolant should be checked at the mileage intervals listed in the service maintenance section. The coolant concentration should be maintained at 50/50 coolant and water, which equates to a freeze point of -36° C (-34° F). Coolant concentration testing is possible with a hydrometer or antifreeze tester (such as the Rotunda Battery and Antifreeze Tester, 014-R1060). The level of coolant should be maintained at the "cold full" of "cold fill range" level in the coolant reservoir. If the level falls below, add coolant per the instructions in the Adding Engine Coolantsection. 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: • freeze protection down to -36° C (-34° F). • boiling protection up to 129° C (265° F). • protection against rust and other forms of corrosion. • an accurate temperature readout from the engine coolant gauge. 171
