Cleaning ENGINE Engines are more efficient when they are clean because grease and dirt buildup keep the engine warmer than normal. When washing: • Take care when using a power washer to clean the engine. The high pressure fluid could penetrate the sealed parts and cause damage. • 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 running; water in the running engine may cause internal damage. 4.0L SOHC V6 ENGINE 297 2009 07+ Explorer Sport Trac (esp) Owners Guide, 2nd Printing USA (fus)
