If it wasnt for Simple Green and Pine oil the Army wouldnt operate.

So FN true.......is it clean, maybe. But it smells clean, good enough for government work.

How much to clean mine? Its nasty.

If you were only closer... lol

Didn't realize there was a cover. I've had mine 3 months have the hood opened several times, If you don't know, you don't know. Even detailed it today after last off road outing

That's a mighty fine job detailing.

The key is pressure.
You can force water past most types of seals if you aim things just right - or is that just wrong....
These ECUs just aren't all that sensitive, and with modern connectors being what they are, there's little chance of water getting in unless you aim at it.

The warning is generic to prevent dopes from taking that car wash wand and aiming closely to force every bit of grease off with pressure alone.
Don't drink the battery acid, warning, coffee is hot, don't stick your fingers in the fan, you know the drill. They have to idiot proof everything these days.
If they made a label that said don't use high pressure then someone would argue that their pressure washer isn't high pressure. So they have to stupid it down for all the maroons out there.
So if you drive through 30" of water, will the ecu stay dry?

I recall the user manual saying you can spray the inside of the engine bay.

I need to check again then. Thanks. It would be great to not have my engine bay as dusty as it is.

This is what mine says under the hood right next to don’t put your hand in the fan. They must really mean it.

What's his name with the deleted JTRD packed mud into his alternate. I'm still baffled on how he did it.

Enquiring minds want to know.

Shorting an ECU? Highly unlikely unless you use pressure against the connections themselves. Most of the connections under the hood could sit under water and be fine.
It's only when you aim high pressure against the connectors that you can blast water past the seals in the connector.

There's pretty much nothing you can hurt in the alternator as long as you don't use chemicals against it. I've washed engine compartments for decades - no issues ever (other than maybe not starting because water got under a distributor cap - pull the cap, use some WD40, and things were fine. That's with cars from the 60s through 80s)

This exactly^^^^!
I pride myself on having an engine compartment looks as good as the outside. Been cleaning 'smartly' for too many years to count.

If anyone really thinks there missing out on the engine cover I have one you can have. All brackets included. Missing a couple bolts but that's easy to replace. PM me. I'm located in Western Washington.
Already gave one away from my JL. This is the last one I have. From my JT.

Just consider your Jeep as circumcised w/o the cover... lol

I picked up my new gladiator a week ago today I opened the hood and notice there was no plastic cover on the 3.6L called dealer and they said it doesn't have one never seen that before

Mine is 2022 and it has no cover
