why?

I just spray some simple green or engine degreaser, let it soak in for a minute, and use a regular garden hose. Works great. make sure the engine is cold too.

Yes you can power wash, try not to get the alternator or the fuse box and you'll be fine.

Just don't get really close to anything because water could get blown past seals. I never cover anything when I wash my engine and it starts just fine every time.

we use this stuff at my dads shop called red hot its alot better then that simple green, its just a very very very strong degreaser not na good thing to use in summer time if it gets on paint to long it can eat threw the paint but i water it down a bit when i clean my engine with it and it takes mud and gunk off in a heart beat they sell it by the barrels and its about 500$ a barrel

When I powerwashed my motor back in June? I covered the ECM, the ignition coil, and went to town. Battery was left alone, and the fuse boxes were fine as well.

NO NO NO! dont powerwash the engine bay!!!! use a hose man... the high pressure will sneak its way into connectors etc. cover the air filter, MAF sensor, Distributor, ignition coil, alternator, battery, and fuse box with plastic bags!!! and go nuts!

you can do it you just have to be really careful to stay away from any electrical connections and such. Also, don't get really close with the nozzle. you will be fine.

I dunno...never heard of anyone having a problem FROM powerwashign their engine. Obviously dont' sit there with 4kPSI on the fuse box...but if your decently careful about your spray stream...you'll be fine.

I wouldn't powerwash the engine unless it is the ONLY way to get it clean. Everything under the hood is meant to come into contact with water, but not high pressure water.

Plenty of cleaners are available that work just as well with less of a potential for damage. I have always been happy with "Orange Blast" as an engine cleaner. It's a general purpose cleaner and degreaser sold at Wal-Mart and other stores.

Since I have to go to a car wash to clean my truck now, I just use the engine cleaner at the car wash and rinse it off with low pressure water. That seems to work fine. I have never had a problem from it.

FWIW, if the engine is cool when I clean it, I'll just clean it while its turned off. If I have to drive to the car wash to do it, I leave the truck running while I clean the engine. That keeps it from cooling down to fast, and I have heard some claims that it is better for the alternator to leave it running.

Your Ranger's owner manual shows you which areas require protection when washing under the hood. Look for something like "Cleaning your Vehicle/Engine Compartment" in the index.

Ford glove box manuals online
