Engine cleaning ?'s

Would like to clean my engine bay, motor with engine degreaser and water, just need to know what not to do and what can handle being wet and what to cover up. has anyone had trouble after they did this? On my titan its fuel injected and nothing is open so i just clean the whole thing with no worries, plus its under warranty. But jeep is alittle different, one would assume since people take them trail riding, through mud holes, etc the motor was built to get wet, along with the throttle body, alt. sensors etc... so what would be the best way to do it, also does it matter cold or hot?

There is nothing to worry about getting wet. I have washed many engings for many years. The only thing i do not recommend are pressure washers. They do tend to force water into connectors and other things. A warm/hot engine is better as grease and grime is looser.

Do you have a picture of your engine compartment that indicates what needs to be covered up?

When I washed off my engine, I got water inside the cab somehow. Just fyi.

Cold engine compartment for sure.
I'm not a fan of a spraying a lot of water in the engine compartment on any vehicle although people do it all the time. I clean everything thing slowly by hand with mineral spirits (the greasey areas) or simple green/fantastic (most other non-greasey dirty areas). I use a lot of rags, small brushes ad tooth brushes. After all is clean I hit most areas with spray car wax or Armoral depending on the material. It is a long slow process but I'm a detail freak and invest the time for the results I need.

If you do go the soap it down and hose it off route use a long very soft bristle brush with the soap to clean most stuff, be gentle around anything sensitive like wiring connections, sensors, Injectorr etc. For the tough dirty nooks and crannies a smaller stiff bristle brush is a must. After rinsing off the soap, blow off the remaining water with compressed air as you wipe in down with clean rags. Wipe everything dry and you'll get a decent job.

If you don't have a distributer just spray the crap out of it. You may get water inside through the firewall but that will be minimal!

What kind of degreaser do you use to make it "shine?" or look clean??

cleaning

So just spray some engine degreaser on and let sit for about 10 min, the spray everything off and air dry, Im guessing you all do this with a hot motor or a cold motor.. also do you start it up right away or let it dry over night...

I use straight Commercial Strength Simple Green on a cold dry engine a rinse with a garden hose. I usually do this about once a year on my vehicles.

For a real oily dirty/greasy engine. Gunk engine degreaser on a warm dry engine and rinse with the hose. This is usually a one time thing with a "new to me vehicle"

I use a brush sometimes on the stubborn stuff.

For the shinny part I have used, Tire Foam, S2000 corrosion protectant or silicone spray. I have sprayed eveything down with WD40 before but it isn't going to stay shinny.

I would actually like to know if there is anything specifically made to spray on an engine compartment for a shine with corrosion/rust protectant?

If you haven't gotten more out of the insurance company than you deserve, then you haven't screwed them nearly as much as they have been screwing you for the past xx years.
