Default power washing the engine bay?

have any of you guys power washed the engine bay with no problem? i have power washed my other cars engine bay with no problem, but i have a bad experience with the coil over plug type cars which have hard time sealing the water away from spark plugs. the car i bought is pretty dirty and i'm going to clean it up pretty good. i bought some engine cleaners but i'm thinking i should keep the water away from coils?

I would personally never powerwash a engine bay, because of electrical/plugs/etc. If you have a 400/430 your engine should have a cover to hide the plugs.

Don't powerwash...the spray is too strong and forces water into areas that show stay dry.

What I do is.... run the engine....then spray SimpleGreen on the greasy areas including electrical sockets (keep away from the spinning serpentine belt, air filter, battery terminals, etc...)...then I use a garden hose, shoot and wash away the SimpleGreen (this should take less than 1 minute), then I immediately use compressed air to blow away the water (this part takes about 5 minutes)...esp at the electrical sockets...all this with the engine running....shiny and new looking...chee hoooo!!

I've done it multiple times on my 300 without issues. I just make sure to keep the engine running and don't point the blast tip inches from the motor.

There's no issues with this, BUT 'make it quick'.

Degreaser - let it sit a couple mins [not on rubber parts], then power was the actual bay except around electrics, simply spray from further away distance on the coils/fuseboxes, etc.

Otherwise your good to go!

i've done this as well with no issues.. and would suggest this method.


I wouldn't recomend power washing an engine bay, but i have done it to an old beater civic, didn't have any issues, but i really wasn't worried about it lol..

well the electronic on engine bay are all sealed by factory to prevent water from going in and damaging them. the only thing i was worry was the coils. i'll try to stay away from the coils. here is my engine bay btw. garden hose won't so it i think lol.
