Mmmmmeh! I did something stupid when changing my coolant and ended up with coolant and chemical flush all over my face, hood, garage door, and engine.

I hosed it down lightly while it was running (and a bit later while it wasn't) and everything was fine.

And, on a separate note, dont ever put cold water on hot metal (like a running engine) or any water at all on running electrical stuff....

Sooo many ways to jack up sooo many things that way

I completely respect you guys that say don’t use water to wash an engine bay, so don’t take my alternative view as a knock, but rather just an alternative viewpoint. Every single vehicle I’ve owned (all 13) I’ve washed the engine with high pressure water. Never has it been an issue. I can’t say for sure that it won’t be for you, but I’ve already high pressure engine decreased my 3.5TT in my EL without any issue. And I soaked it. Big time. It’s gorgeous now. Should have taken a pic.

If you want to really make your aluminum shine, get a good aluminum brightener (I buy a gallon jug of it at NAPA) and dilute it a bit with water and then spray it on your engine. Don’t get the stuff on your painted surfaces if you can help it. Let it sit for a bit and then rinse it really well. Will clean and brighten even the saddest metal bits. Awesome stuff. Don’t breathe it in. Anyway, I’ll always powerwash my engine bay. I don’t aim the nozzle directly at any electronics nor do I even get the nozzle very close to any surface in the engine bay for that matter, but it does do a good job. And use a good engine degreaser (gunk or the like). Spray it down good with the stuff and let it sit for 5-8 minutes. Be patient, it needs time to emulsify the grime. Then power wash it off.

The top of a 5.4 v8 is NOT waterproofed... not sure if they thought they were making it to be waterproof or not, but fact is it just ain't. Period.

The 3.5 TT Eco looks like it has a fairly solid cover on there though. Nothing much to hose, however, just wipe it off with a cloth when its cold.

Whoa, I didnt even realize ours came with covers, USFS must have lost or chucked mine....


Looks like you hosed her down ~real~ good (or at an angle from the side) to still drown a plug & coil with that on

My 05 didn't have a cover.

I’m with Muddy. I’ve washed every engine in every auto I’ve ever owned with a power washer and never once have had an issue. Guess we’re just lucky
