Cleaning • Do not spray a hot engine with cold water to avoid cracking the engine block or other engine components. • Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts that require cleaning and pressure rinse clean. In Canada use Motorcraft Engine Shampoo (CXC-66-A). • Cover the highlighted areas to prevent water damage when cleaning the engine. • Never wash or rinse the engine while it is hot or running; water in the running engine may cause internal damage. • Never wash or rinse any ignition coil, spark plug wire or spark plug well, or the area in and around these locations. PLASTIC (NON-PAINTED) EXTERIOR PARTS Use only approved products to clean plastic parts. These products are available from your authorized dealer. • For routine cleaning, use Motorcraft௡ Detail Wash (ZC-3-A). • If tar or grease spots are present, use Motorcraft௡ Bug and Tar Remover (ZC-42). WINDOWS AND WIPER BLADES The windshield, rear and side windows and the wiper blades should be cleaned regularly. If the wipers do not wipe properly, substances on the vehicle's glass or the wiper blades may be the cause. These may include 267 2011 MKZ (378) Owners Guide, 2nd Printing USA (fus)
