I find that it's easier to just not look under the hood and pretend that it's clean and pretty under there. Otherwise it will require effort on my part.

 

Have you ever taken the doors off ????? ALL electrical connections have water tite rubber seals so even if you spray them with high pressure water should not short out ( as said; your JEEP can traverse 3 feet of water or so it is in the Owners Manual )

ON the TPS if the high pressure hit it hard enough it is plastic and could shift its position; but you should be able to shift it back in position without replacing it SHOULD !!


I have a 2000 Volvo 18 wheeler that I have the Truck Stop Washes ( extreme high pressure that can cut your skin if directed at you ) clean the engine bay all the time and it has the same electric connections as the JEEP. NEVER ANY PROBLEMS !!!

 

This is what we do. Just before hitting the tracks

Spray a can of WD40 all over the engine throughly especially on raditor fan belts electric connectors everywhere I even spray WD40 on inside of the wheels underneath etc

After wheelling cover the air intake with plastic bag, cover the fuse box with plastic bag... let the engine cool down while you are washing the rest of the body and then slightly spray soapy water followed by low pressure keeping away from distributor fuse box plugs etc after that a quick burst of wd40 to keep things lubricated

spraying wd40 prior to wheeling helps a lot keep the mud non stick and lubricates it also nicley.

 

I've ALWAYS hosed off the engine while it was running, of course a little Simple green wouldn't hurt. I usually do it at the car wash............wasn't that a song ....or a movie from the 70's?

Rock On

 

x whatever number this would be.

Simple Green is good stuff!!!

 

x2 on 2 things: the "tire cleaner" spray at the car wash and be sure to check the radiator.

And when I am rinsing off the engine after the tire cleaner setting, I don't pull the trigger, just use the lower pressure.

Our radiator got so filled at one point I had to pull the electric fan so I could get to the actual radiator better to get the fins clean. I really don't like mud

 

Off - don't want to suck any water into the intake.

 

I thought WD40 was bad on the rubber parts?!?! Hoses, belts, etc???

 

I was a big fan of Simple Green before I tried Scrubbing Bubbles (for a bathtub/shower). Scrubbing Bubbles gets all of the mud off of the plastic and makes it look brand new. Give it a shot......

 

Drive it through a clean water hole after all the mud holes
