1996 Mercury Mystique Owner's Manual - Page 211

Servicing Your Mystique Check the engine coolant level in the engine coolant reservoir at least once a month using the following guidelines. When your vehicle's engine is cool, the coolant level in the engine coolant recovery reservoir should be at or above the MIN mark. When the engine is hot, the coolant level should be at the MAX mark. If the level is below the indicator mark in either condition, coolant may need to be added. The coolant additives also protect the entire cooling system from internal passageway corrosion and these additives lubricate the water pump. The coolant should be serviced as noted in the Maintenance Schedule and Record booklet. Adding engine coolant RWARNING Do not put engine coolant in the container for the windshield washer fluid. RWARNING Never remove the coolant recovery cap while the engine is running or hot. 1. Before you remove the cap, turn the engine off and let it cool. Even when the engine is cool, be careful when you remove the coolant recovery cap. 2. When the engine is cool, wrap a thick cloth around the cap and turn it slowly counterclockwise to relieve the pressure. 3. Step back while the pressure releases. 4. When you are sure that all the pressure has been released, use the cloth to turn and remove cap. 5. Stand away from the reservoir opening. Hot steam may blow out or hot engine coolant may even splash out. 215
