Is it safe to pressure wash engine?
This guy, who actually seems to know alot about cars. Says its ok to pressure wash, that the engine breaths alot better with out all that gunk… But i started doing it and it just sounded like it did not like it, (belt stopping/squeaking)-from getting wet obviously… So i stopped, he said just deal with the horrible noise cause in the end its worth it… He says older vehicles you shouldnt but newer vehicles are sealed very well. Drive a 2002 ford focus zts by the way
Well you don't want to do it while the engine is running… That would cause problems. But generally speaking, yes, it's perfectly fine to pressure wash an engine. It's quite common to do. The key is just knowing what you're doing and avoiding certain things. Spark plug boots can be ripped, so can other sensitive rubber seals that would be exposed to the pressure. You won't hurt the belt, or pulleys or anything else doing it. Oh, and DON'T spray inside the intake (should be common sense, but you know that goes…)
I have been okay most of the time and did expensive damage once: the fuel injector connector boots were torn and the connectors corroded. $2000 for an engine harness…
It looks nice but does not help at all (it helps the engine BREATHE?), might hurt. Steam is a much better idea if you are going to clean the engine bay.
Well, I will say this I have worked on cars for more then 30 years. I power wash my engine about twice a year and have NEVER had a issue
Do not freaking do that.
Go to the carwash bay. Look at the little dial. It says engine cleaner. Use that ****. Just spray it on let it sit and lightly rinse it off. I have been doing it for years to my cars never had a problem. My cobra, my mustang gt and all the other cars i have owned with out a single problem for many years, a trans am, a camaro, a gto, a grand prix GXP the list keeps going.
- Differential pressure switch causing check engine light? 1997 Ford Taurus. I don't remember the exact code but it said something was wrong with the upstream differential pressure sensor. The car doesn't run any differently. How do I fix it?
- Performance Camshafts safe to drive without a tune? I just installed some Ford hot rod camshafts in my 2010 mustang GT and also have shorty headers, a cold air intake, cat back exhaust, and 24 lb ford racing injectors and was wondering if it is safe to drive for 2 weeks without a tune, my dyno appointment isn't until the 22nd
- I took my car throughout car wash and water filled up the left headlight and blew the bulbs! What caused this? My car is a 2006 Ford Freestyle and I've had it for a few years now. Do I have to take off the whole assembly or can I just take the headlight out and fix it?
- Safe to buy a truck with high miles and repair it? I was just wondering if it would be a good idea to buy a 2007 ford f150 with 233,000 miles for only $6,000 and just save up enough money for a new engine ($3,000-4,000 more dollars) when it goes out and have a pretty new truck with a new engine. It's a very clean truck in EXCELLENT condition, it just has a lot of miles. Or is this just a really bad idea? I attached a picture of the truck.
