2005 Engine Bay Pressure Wash?

Has anyone pressure washed their engine? I watched a couple YouTube videos and as I assumed it would be smart to stay away from the fuse box and Distributor. My question is the Alternator...? Being that it is located on the back side of the engine and away from normal road spray, what should I do? It's not like it's on top and is the first thing you see when raising the hood and I could simply wrap it. I haven't changed the stock air intake so that won't be an issue.

I was considering doing this when Spring comes and clean it up a bit. I was curious of anyone had done this, and if so, what's the best way?

Thanks,

just cover it

That's what I figured, thanks for the reply. It would be more of a soap-up and hose-off it's not that dirty. lol

well use like a good engine degreaser

Any suggestions?

Hey there!
I used Gunk on my engine/bay, it worked very well! Not very expensive either :)

I shall acquire some, and see how well it works. My engine isn't really greasy, it's just covered in dust and road spray...

Thanks for the suggestion. :)

while i do not believe there is any good way to do it, doing it while it is running would be my preferred method. only because it will stop running while you are spraying what you will need to replace for getting it wet.

I agree with rabbit. I go to auto repair class at the community college and there is a detailing class working next to us. They clean the engines with a strong degreaser and a hose. The always have the engines running because if the engine starts to stumble they know not to spray at that location anymore. They say to always have the engine running for this reason. They also say don't use a strong spray. They get the engine warm, spray on degreaser. let it sit for 5 minutes, then wash it off with a medium spray. Their engines always end up sparkling. I would stress, as do they, don't use full pressure power wash when doing this. You can wind up force water in place you don't want it, like electrical connectors. They would give you tons of pains in the ass down the road.

Would this procedure be considered the right way to clean the engine? How To Clean Your Car's Engine - YouTube I would like to try and clean the engine but don't want to F anything up and this looked pretty easy to do.

Wouldn't getting a hot engine wet create steam, condensation, and humidity inside sensors? Crack something? I once washed my engine (previous car) while hot and cracked the coil pack and engine wanted to die. From that time, i always washed the engine while cold first thing in the am and never had that problem again.
