Cleaning the engine compartment

Register to hide this ad
A decent all-purpose cleaner and brush to agitate the dirt is all you really need to do a good job. Rinse with a low pressure/low flow of water.

When time is an issue, I love using CD2 as well. Buy their can of cleaner and a can of their detailer and you are all set!
 
I usually just use the pressure washer at the car wash, the days of getting water in the distributer are long gone. I would just make sure you drive it afterwards to dry everything out properly before you park it.

I disagree with you here regarding the pressure washer. The distributor isn't the only thing you need to worry about. Water getting into the hundred of wire plugs and computer modules would be my first concern and would be costly should you fry something. My .02 cents.
 
Before I got my 4th Generation 4Runner...I would be scared to spray water in the engine bay.

I've sprayed the engine bay a few times.


• Spray (garden hose pressure) water in the engine bay when the engine is cold.
• Don't forget to spray the radiator, that thing is a vacuum for dirt.
• Then go drive the vehicle around for like 10-15mins.
 
I agree with M1911 here. The only thing that I do and have done for all my cars is to wipe everything down in the engine compartment with a moist towel. I do this quite regularly and this prevents any dirt from building up. There are obviously going to be places where the dirt does accumulate, but water and electrical components are not the best of friends- so I do not ever spray water there.
 
I've used Simple Green as well with great results. Then I spray it off with the hose on "mist" and start it up immediately to dry it off. Worked great for me in the past!
 
Simple Green does work well. The only issue is it causes bare aluminum to oxidize more so than with some other type of cleaners. If this is something you don't mine, have at it. I still use it, but follow with some other products to protect the aluminum. Another product I use is Amazon.com: Gunk CEB1/6 Engine Brite Citrus Engine Shine Degreaser and Detailer - 15 oz.: Automotive. Just spray it on, let it sit, then spray it off. Leaves the engine bay shiny with a nice citrus scent. It does cause dust to attract to it more so than normal. I'll have to give the Turtle Wax stuff a try.
 
Read about Condensation

Guys,

If you are pressure washing your engine bay take care! Some of these pressure sprayers will really do some damage over time. Read some threads on the web about engine condensation. Many of these sprayers are strong enough to move water through seals. Several people with oil contamination from water and condensation build up inside the engine due to using power washers. You get the infamous "grey" oil and sticky oil cap.

No need to Clean Your Engine...

I bought my first car in 1978. I've never cleaned an engine. No need.

- No need... Unless sudden rain storms come out of nowhere in the middle of nowhere...
