Time Lapse: Washing Engine Bay

Difficulty Level

Areas to take caution around when washing:

• alternator
• coils/distributor
• spark plugs
• spark plug wires
• fuse panel
• oil filling places (engine oil, transmission oil, power steering)
• brake fluid reservoir
• intake
• air filter

Tools/Supplies Needed:

• pressure washer
• hose
• water
• air compressor or vacuum or cloth or leak blower
• soap/degreaser

Procedure:

• making sure your engine is cool, open the hood and spray the engine down with the Spray Nine cleaner
• let it soak for 3-5 minutes
• using a pressure washer, wash the soap, dirt, grease, grim off the engine being careful about the areas I cautioned about above
• if there is still some dirt remaining, you can respray the area with soap and pressure wash it again
• harder areas you can scrub down with a brush
• leaving the hood open, let the engine bay air dry
• using compressed air or a wet/dry shop-vac, you can speed up the drying process

Video time lapse on washing an engine bay. All components which can be affected by water have been covered using a plastic bag. A pressure washer isn't need as a regular hose can be used, but a pressure washer does make it a lot easier. It is always good to keep a clean engine bay as it's nicer to work on, aesthetically better, and also helps point out any new leaks. The particular tutorial was done on a 1998 Ford Ranger with a 2.5L 4cyl.
