No plastic cover on my 3.6L

[rwu355]

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

what is your procedure for cleaning the under hood insulation?

My Gladiator has a metal engine cover.

Mmmm... I think that means you're probably going to die in a fiery crash. Sorry.

I hope it doesn't happen, but just in case it does.... can I have your stuff?

don't be sorry you can't help yourself

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?

Sorry. I don’t buy it. My wife’s ‘22 volvo doesn’t have that label. And it’s a plug-in hybrid with LOTS more sensitive electrical systems. Almost every car I’ve owned has had a fan blade warning for idiots, but this one is the first with this warning.

Just the same, simple green soak, brush and garden hose.

Nice and clean for cooking…
Engine Bay Burritos!

Was there a purpose or was it just cutting costs?

The purpose was to make it easier and more spacious to cook lunch!

The secret to keeping a clean engine bay is to keep the engine bay clean.

I spray down the whole engine with simple green, let it soak for 10 min. Take an old paint brush to break every thing loose. Then just spray down with water hose. I don't hose down the alternator, battery or fuse box, then wipe everything down with a micro fiber towel. Been doing this for years and never an issue. Always when the engine is cool. Used a little more than half of the spray.

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

My two cents for there being no cover is so the intake can run cooler. Put the cover with that insulation pad on it back on and the air temp going through will increase. It’s the engineer’s attempt to lower the air temp. BOOM ?! Raise your hands if I’m right.
