Engine compartment cleaning

[mrkoopa]

Howdy yall,

Did some searching cant really find a concise answer in the manuals, PMCS items, or anything on the forums here. How do we feel about hosing out the engine compartment? Ok to do? Keep it away from the genhead? spray and pray? I note in at least one video @CallMeColt does bring some water into one of his units in one of his videos. Want to get some of these greasy spots taken care of, and some residue from coolant after the radiator removal and repair.

Thanks again for the wisdom.

I used to do it all the time, every machine I ever bought for a thorough steam cleaning.
Stay a little bit away from the generator, alternator etc., but don't be overly worried.
When you're done you can blow it off with compressed air or a leaf blower.
I've even lightly washed inside the electronics enclosure on units with tons of fine sand in there, just dry it off before trying to run it, and stay away from the holes in the back of the gages.

Think about this, every time it rains and you are driving the fan is pulling in and spraying water all over the engine compartment. You do need to be careful with pressure washers, none of these components were designed to resist 2500 lbs. of water pressure. But at least military vehicles were designed to have the engine mostly under water.

I just washed a 802 couple weeks ago. Main thing do it on a dry sunny day. Run unit first a couple minutes to a slightly warm temp. Shut down unhook a battery. Do your cleaning, leave doors open. Wait a day to start up. Haven't had the control panels cleaned yet.
