Check the level of the engine coolant at least once a month, but preferably each time you stop for fuel. Simply check the coolant reservoir, located in the engine compartment. The coolant should stay slightly above the "FULL COLD" mark. Adding engine coolant RWARNING Do not put engine coolant in the container for the windshield washer fluid. If sprayed to clean the glass, engine coolant or antifreeze could make it difficult to see through the windshield. 319
