Engine Cleaning

So this past Christmas break some friends and I took our Jeeps out for a little playtime in the mud. Now our engine bay is really muddy and I was wondering what is the best cleaning treatment to clean this up. There is currently no problems but I want to prevent them from arising by cleaning the engine bay.

Just don't wash it out at a do it yourself carwash. Most have strict rules against it because the motor and oil grime fouls their system and they can get busted on enviro rules. Just a heads up.

^^^^ Thats true. Ive been banned from the carwash near my house. I was warned "numerous times" about bringing large amounts of mud to the wash stations. Although I never did the engine compartment, still lots of mud alone can foul the wash stations.

Thanks for all the input. The car wash around us is pretty cool with us Jeepers, I think he used to have one. But we also make it a point to clean up around us. I was just worried about spraying something in the Engine bay that could cause harm, but after watching the Gunk video I'm reassured now.

Cover anything electrical (pcm, alternator, fuse box) and any entries into the engine (throttle body if you remove the intake) with plastic grocery bags. I use simple green and a hose but any degreaser/small scrub brush will work great. Avoid spraying sensors directly if you can. When your're done bring the motor to running temp so any pooled water burns off.

This video is like the one up top but instead in showing off all of Gunks products it uses the heavy degreaser on a TJ and it shows and explains what to cover up which is only really the air intake.

Well, I tried the Gunk today and it worked great. It may take a few more times to get it back to factory but I won't waste my time going that far. I did remove most of all the mud I put into it. I just sprayed the Gunk and let it sit for 20mins, then sprayed it off with a water hose. I spent about 10min spraying water. Then drove my Jeep to town to help it dry since its winter and didn't want the pulleys to freeze for the morning.

Probably because it's not his jeep and couldn't care less if it gets an electrical gremlin under the hood. BTW I wouldn't use that shine stuff they sprayed on after cleaning it's a dirt magnet.

I didn't because I didn't feel the need too. If you think about it everywhere there is mid water had landed. So it is no different on the trail or cleaning the engine. I would not stand there spraying water for minutes on end on the fuse box or battery. I had no problem when I did mine and my fathers TJ.

Another thing we did was after I cleaned them we brought the jeeps up to temp and drove them for a few miles just to get the water blown and burned off.

Your engine gets soaked every time you drive through a heavy rain storm your engine plus battery and fuse box gets soaked. As I have said before just don't hold the stream of water in there for to long and drive it after you clean it and you will be fine.

I have always washed my engine with water but now with owning jeeps I was looking at something to use to help clean it. Hope this helps.
