Maintenance Note: Automotive fluids are not interchangeable. Do not use engine coolant, antifreeze or windshield washer fluid outside of its specified function and vehicle location. Do not mix different colors or types of coolant in your vehicle. Mixing of engine coolants may harm your engine's cooling system. The use of an improper coolant may harm engine and cooling system components and may void the warranty. Use prediluted engine coolant meeting the Ford specification. See Capacities and Specifications (page 353). In case of emergency, you can add a large amount of water without engine coolant in order to reach a vehicle service location. In this instance, qualified personnel: 1. Must drain the cooling system. 2. Chemically clean the coolant system with Motorcraft Premium Cooling System Flush. 3. Refill with engine coolant as soon as possible. Water alone, without engine coolant, can cause engine damage from corrosion, overheating or freezing. Do not use the following as a coolant substitute: • Alcohol. • Methanol. • Brine. • Any engine coolant mixed with alcohol or methanol antifreeze or coolant. Alcohol and other liquids can cause engine damage from overheating or freezing. Do not add extra inhibitors or additives to the coolant. These can be harmful and compromise the corrosion protection of the engine coolant. When adding coolant: 1. Unscrew the cap slowly. Any pressure will escape as you unscrew the cap. 2. Add prediluted engine coolant meeting the Ford specification. See Capacities and Specifications (page 353). 3. Check the coolant level in the coolant reservoir the next few times you drive your vehicle. Adding Engine Coolant Note: Do not use stop leak pellets, cooling system sealants or additives as they can cause damage to the engine cooling or heating systems. Your warranty may not cover these damages. Note: During normal vehicle operation, the engine coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate that the engine coolant has degraded, nor does it require that you drain the engine coolant, flush the system or replace the engine coolant. 286 MKZ (), enUSA
