Washing my engine

Is it safe to pressure wash my engine and does it have to cool down first before I wash it?

Re: Washing my engine

Just be careful not to soak it,cover your alternator with aluminum foil or plastic bag. No need to let it cool down,get some simple green or some type of engine cleaner and follow the directions. If you use a engine cleaner do not get it on your paint.

Check YouTube for some engine detail videos there are a ton of those and it will walk you through,some even say stick with the garden hose method as the pressure washer can be to much. Is this your first time detailing a engine bay?

Re: Washing my engine

Some owner's manuals (at least for trucks/SUVs) that I have seen will she you exactly how to wash your engine and not hurt it...or a HANES manual..it shows you what to cover and how to do it...and don't wash it hot...metal expands when it's that hot then shooting it with such cold water is a big shock...just be careful when you do it...mom ended up throwing a plug because of it.

Re: Washing my engine

I don't bother to "wash" my engine bay, I find it takes away from my detailing it myself. Instead, I get a lot of rags, and I go to town in the engine bay, cleaning everything one at a time by hand, including firewall and the cars chassis.

As for Engine Bright, it's good, but I find that when I did do my engines with engine cleaners, that it left a sticky residue on the engine. And after time driving it, I would look at the engine and it woudl look like sandpaper....everything stuck to it!!

IMO, if you have time, and you find it to be a stress relief therapy, like me, then just do it by hand with some rags.

Re: Washing my engine

That's also gonna depend on how dirty it actually is. Sometimes a dirty engine needs a bath just like you and me but after that, all you have to do is stay on top of it.

Re: Washing my engine

I occasionally power wash, but usually just use a hand full of rags. I opened the hood for my cousin the other day, and he was amazed how clean it was, being a daily driver. I only power wash it after road spray makes it's way onto components... I never spray electronics hard...

Re: Washing my engine

I bought a 90 Astro van in 92 and the van had 170,000 highway miles on it. When ever I stopped, the temperature gauge rose. A friend suggested that I check between the condenser and radiator for debris. I did and found a dead bird, small twigs and more bugs than you can imagine. He told me to be careful pressure washing because it can bend the fins over on the condenser and the radiator. Anyway, after cleaning, my van engine ran cooler and my air conditioner blew colder..

Re: Washing my engine

I recall a kid when I was in highschool doing this to his car and the thing didnt run again for like 2 months and his parents dishing out a few hundered dollars.

Just use caution or do it by hand to be safe.

Re: Washing my engine

i would recommend trying simple green first just spray it on stuff and wipe it off, may take a few applications (let it sit a little bit) then wipe it off. Test it on plastics first but for metal it will be ok etc.
