Engine Wash?

Have any of you used engine wash at a car wash on your 4.0? I have been mudding a lot lately and the engine is covered it dirt. Thought about using the engine wash feature at the car wash up the street. Thanks!

I just hose it down outside the house while it's running and try to avoid my distributor cap and wires. If you have a coil pack you should be fine to just hose it down but i'm not 100% sure.

Actually cold water on hot engines can caused cracked heads and manifolds. The best bet is use scrubbing bubbles on a cold engine and rinse. Then allow teh engine to air dry before attempting to start it so you dont short anything out.

That is the safest way to do it.

And as for teh scrubbing bubbles, i discovered it outperforms anything you can think off for removing dirt and grease from engine compartments.

I do it once and a while and I must say, my motor looks beautiful.

This is what I do. I have done this with all of my other cars before.

1. Wait till motor is kinda cool. If you just drove it, let it sit for around 30 minutes.
2. Hose it down/If you removed your airbox, make sure that the intake doesn't get wet.
3. Spray simple green everywhere.
4. Let the SG sit for 5-10 minutes
5. Hose it down removing all of the SG
6. Spray armor all everywhere(this keep the hoses supple and fresh and it gives your enigne a brilliant shine)
(Good luck mate/Mud stains suck donkey).

Easy on the alternator. If it gets too wet, the bearing dries out and cooks it. I've seen it happen!

I do mine once a year up here in the NE, unless it's been in mud, I park it facing the most sun it will get and lightly hose it down with normal water, spray it with a good cleaner, then use a stiff parts brush to break stuff loose, again with the light spray, then I leave it alone for 3 or 4 hours and let the sun bake the engine bay. If it's really dirty and it's really going to get a drowning I disconnect the battery but it's a PIA going thru the relearning process on the ECU. I figure once the water is all evaporated from the nooks and crannies on the intake manifold it's dry pretty much and start it up then let it idle for a while then take it out.
Personally I prefer rocks over mud.
