IS it ok to spray down your engine bay? I'm asking cause my radiator cracked and spewed coolant all over the place. Head, pipes, lines, etc... looks ugly. I did some minor clean up work but can't get the all those nicks and crannies.

What should I cover up? All connectors? Filter. Oh and I'm not talking like a spray down as if I were watering plants outside, I mean a quick power spray @ a say coin op car wash and hose down the bay for about 15-30 secs?

Thanks

 

Cover up anything electrical in the bay

 

i cover my filter then spray the **** out of the bay. have done it over 20 times...your hood has a giant hole in it.. obviously it wouldn't be there if water was going to ruin everything.

 

Just cover up the air filter if it is an open element and spray away. All the electrical connectors are of a Deutsch style which means where the wire entire the back of the plug it passes through a rubber grommet and also the male or female end has a grommet so when they are connected they are again sealed. Just be caseful not to get close to electrical items or fins on the radiator/IC/AC condensor and things like that which the water PSI will destroy.

 

Cover the air filter, go to town.

 

Do u have an open filter element or is it the stock box? If its the stock box u don't even have to cover it. If its open element cover it. I worked at a car detailer for two years. Manheim auto auction and never had a problem with steaming the engines. We did it while the motors were running as well. Don't ask me that's just how they said to do it and never hyrolocked a motor or anything. I would do it with the motor off tho on my own car just to be safe.

 

From past experience this has not been a good experience for me. Had an 01 Saleen Mustang and sprayed it down at the carwash to clean it and had to have it towed to my local dealership. They then had to have a special SVO technician work on the vehicle. Good thing they were able to get it covered under warranty. Maybe different with these cars.

 

like mentioned above, cover the filter and just be extra careful with the brake fluid reservoir cus you do not want moisture to get it there.

 

+1, just cover up any electrical components, or anything that may get "water" into the engine. Don't spray down one area for too long, make sure you spray even everywhere though.

 

just let it dry for a bit before driving.

 

If you can, use some compressed air to blow the water away that could be sitting in places where it wouldn't drain itself.

 

Make sure you don't spray filter, and try to keep water out of the spark plug valley... Plugs get wet it will ruin your afternoon

 

Asides from covering what needs to be covered it is best if you let it dry for 24 hours then it is safe

 

I'd also suggest to wipe everything down to keep from getting water spots everywhere and on everything as best as possible. I also wouldn't hose down a car you were just driving hard, the cold water on the hot manifold doesn't make for a good combo.

 

I used to work there too when I went to school in nashville (NADC)....I was one of the guys that drove the cars to all the different place, the shop, back lots, auction line, etc...

I agree with most, cover the filter and as long as you keep the sprayer moving you should be fine. It's how all my detailing friends do it (they also say to do it while engine running too not sure why).....Blowing everything off with compressed air would be the best but deff not necessary, I just take it for a good drive to get heat inside the engine bay to help dry the water out. I used to do it everyday on the short buses with gas engines and they were fine. I do it with tractor trailers everyday but they're diesel and a different ball game (no ignition system) but still has plenty of wires and theyre fine.

When I do it at work I spray it down to get the dust off, dry it with compressed air, then put a light coat of wd-40 on most stuff to help keep it from rusting and displace any water (hence the name..WD-water displacement)
