Power wash engine??

Is there a way to do it? I've heard from someone to just cover up the electrical stuff and it'll be fine and then someone else said it shouldn't be done like that at all. Which is true? My engine is reallly dirty with dry mud a lot of places.

You're better off just to use the hose at your house. Get a bottle of simple green and spray everything down then let it sit for a minute then spray off the engine with an easy setting and let it air dry and it'll look good as new.

I do it at home. First thing in the morning or afternoon or whatever....engine cold not even started for the day.

I degrease the engine then pressure wash. Then a heavy coat of simple green, let soak some, then pressure wash. I don't cover anything up and wait a few hours before starting. Just watch out for that intake tube and filter area.

Better off using a garden hose, but if the pwasher's out anyway, I use it.

I would never use a pressure washer in the bay. Simple Green and a garden hose with a spray attachment is pleny. Always shrink wrap the fuse box, alternator, coil packs, and if you have an exposed filter.

I did it to my 5.0 motor in my truck and i just avoided spraying my intake filter, my fuse box and my coil packs... everything else you can spray and wait to let it dry then drive it. :)

I've never had a problem. It's a good idea to not spray the alternator too much, but most of the other electrics under the hood are well protected. On my Fairlane, I just covered the air filter, but with the Ranger, since it's enclosed, no worries.

Just be careful when around the coil packs, when we do Supras that is the first thing we do. If water gets into the coil valley, good bye ignition.

no point in repeating whats been said over and over again so i will add that i lightly spray the coil, fuse box, alt, dis etc, and wipe them down by hand to make it look good. the rest i giver hell with a garden hose.. just to get the big chunks of mud off..

I never cover anything up and its never been a problem. Dont just nail the alternator with water and dont just sit there and hose any electrical components and youll be fine. i even give the battery and fuse box cover a quick pass to knock off any loose dust. no its never hurt anything and every body shop ive been to does it the same way to the cars they work on.

just about any underhood component has a weather tight connection on it. A minor spraying isnt gonna hurt anything. Just dont try to hose it like it's a Bugatti in a lake.

I have never used my pressure washer on my engine. I coat the engine with Castrol Purple Stuff and hose it down. Do not cover anything and never had any problems with any of the vehicles I have done this to.

i heard they were making submersible veyron's...


i pressure wash the **** out of everything in my engine bay... don't really steer away from anything particularly... don't go all out on electrical components, but you don't have to avoid it... if you have a distributer cap, there is a possibility that your truck won't start, if this is the case, pop your dirstributer cap off, and run a towel through the inside, over your rotor, try to dry it as much as possible, then give it a quick squirt of WD40 (WD40 stands for water displacement 40:1, which means every drop of wd40 displaces 40 drops of water) pop your cap back on and fire 'er up!

Just did this again yesterday, I cover the battery/fusebox/alternator/coilpack/air intake and use almost a whole can of Engine Brite foaming degreaser and a garden hose, then when its dry, I spray a little Stoner Trim Shine on the hoses and engine block. Works great and I've never had a problem doing it like this.

For the actual engine bay walls where all kinds of dirt builds up, I could see power washing being beneficial. But theres no need for the engine itself

No. Might want to google why it's called what it is. The 40 is because it was their 40th attempt at making it.

Origin of the popular lubricant WD-40's name

Quote:
According to the WD-40 Company, the name "WD-40" originated in 1953 when the product was first developed. The company, originally known as the "Rocket Chemical Company", was trying to design a protectant for metal parts on rockets to prevent rust and corrosion by displacing water... hence the "WD" for water displacement.

The "40", on the other hand, indicates that the formula (still in use today, by the by) was the 40th attempt to get it right! And they did. Talk about persistence!

would it be possible for one of you guys to take a shot of your stuff covered up before spraying it?

This is also what I do. Takes 2 minutes to wrap up the electronic parts in a plastic grocery bag.

I pressure wash mine all the time, probably 3 times a month, no issues ever on anything I've ever owned. Try not to cut wires with the high PSI water, also watch out for stickers and decals when using higher pressure washers....they really fly when you lift a corner up.
