Engine Bay cleaning.

I just got my JK back from the shop. Everything is covered in mud. I'd like to hose out the engine bay. What needs to be covered/not to get wet?

Just be careful of getting too much water in the intake. You might even want to stuff a rag in the air box opening and then blast away. Everything under the hood can take water without problems.

make sure if you use a pressure washer to avoid full pressure on electrical components

LOL! That's why she was in the shop to begin with and why I have mud everywhere. Thanks. I popped the hood and was about to take out the hose when for some reason the ESP caught my eye. I was like, "I wonder if I should get this wet..."

Press and seal (food wrap) works good for sealing items before cleaning. Aluminum foil too, if it's not covering anything that could possibly arc. Simple Green works great. I spray the SG when the engine is cool, and let it soak for 15 minutes. Then I start the engine and rinse the engine with low pressure water.

Engine Bright is great for the greasy stuff.

Iíve been washing all my Jeep and cars for quite a few years now exactly like I described above and never once had a problem. Usually I spray the engine and underside of the front with Engine Gunk prior to hosing it all off. Now if your thinking I meant to go to one of those pay washers your wrong. My water source comes from the garden hose with nozzle set to jet spray.
Getting mud into the electrical parts prior to hosing it off is a different animal all together.

Simple Green is your friend. I use it on all my engines. 1 it's not toxic, 2 it will not etch any aluminum, 3 it's totally safe on all rubber and plastic and it does a GREAT job degreasing.

Wouldn't getting it steam cleaned be the safest options and get it the most clean?

I normally just use the garden hose, and I used a de-greaser at one point, but it never makes the engine bay look like new. Heck I don't even know if a steam clean would make it look like new.

Who does Engine steam cleaning besides dealerships? I'd certainly pay to have my vehicle "dealership" clean every couple of months, but your not going to find any small time detail shops that are going to be able to get your jeep that clean.

turn the car on and let it get to about half temp before you do it. dont let it get too hot. quarter way up the temp gauge and turn it off.

i spray everything... just dont stay on the intake, battery, fuse box too long. because of the little bit of heat it will evaporate fairly quickly. but not too hot where everything will smoke and steam up..

just dont directly shoot the wires (for too long) and use some common sense.

should be fine.. especially if its a little warm

Been 4yrs now pressure washing the Engine comp. just don't soak the air box or alt/fuse box you should be fine . I took all the elec. connectors apart and put dielectric grease in them ...........
ALL's fine and should be for many years to come .
My long time buddy (last love vehicle) had over 760,000km on it with the same treatment .. no worries .. no problem
Just don't over do it ................

A toilet brush works well for getting in all of those nooks and crannies

Thanks for the tips guys. The backstory is that last weekend I hydrolocked my engine and sent a rod through the block, so my JK has been at Jeep getting a new engine. She was all muddy from the offroading I was doing, and when I got her home yesterday, I popped the hood and saw I had mud everywhere, so I was just looking to hose off the mud and getting her more presentable. I used to detail cars, so I know enought to throw a plastic bag over the distributor, but the I saw the ESP and was wondering if I needed to cover that area also (even though there are signs of muddy water there too) Anyways, that's for all the insight, today is Jeep cleaning day.
