I was then attacked by like 6 people saying I obviousely have not ever detailed an engine bay before and blah blah its safe to just spray it down with a hose or power washer. I couldn't get my point across how stupid that seemed to me so I gave up lol...
also if you do end up spraying it down... wait as long as possible with the hood up before starting the car! try and let all the water moisture evaporate.. and if you have an air compressor.. doesn't hurt to blow some compressed air around the cops to get that water away!...
Jeez well they'll get the last laughs. Ford actually outlines the steps in the owners manual.
I've done it this way for years and haven't had any issues. If the engine is dusty, and if there is not a lot of grime it's better to wipe areas down.
Step 1. Make sure the engine is ice cold before starting.
You want it cool since there is a slight possibility that you can crack the engine block by throwing cold water on it.
Step 2. Cover fuse box, battery, distributor cap, air intake, and I cover the alternator as well. Plastic bags work well
Step 3. I spray the entire bay with simple green and then lightly brush with a soft brush or old rag.
Step 4. Lightly rinse, I hold the hose at an angle off to the side, keeping the nozzle on the lowest setting.
Step 5. Pull off plastic bags a little water might get onto those areas , but just wipe it up, and you'll be fine.
Step 6: Dry the bay with towels and a forced air dryer, or compressed air will also work. Leaf blowers & shop vacs with a clean hose work well for this.
At this point you have 2 options leave it alone, or dress it up to your liking! I like to use SprayWay instant shine it looks great, and it doesn't attract dust.
I usually do the engine first when detailing a car, it's not mandatory, but I don't love the job enough to go back and clean the overspray up.
