Just curious. making sure it wont make any sensors or problems later. Thanks

 

no pressure wash. no gunk steam cleaner either. mild soap and soft brush for dirty areas and a garden hose is o.k.

 

With Infinitis, no. Every VQ I have touched with a strong stream of water have tripped something. Nothing permanent, but enough to have to try out an MAF for an hour or something.

I usually stick with a quick detail spray and lower grade MFs. If dirtier, a mild dilution of APC and maybe a gentle stream of water to rinse.

If you don't mind buying it online, CD-2 Engine Detailer looks t1ts underneath the hood.

A Saab I did with APC, multiple brushes, rinsed, then saturated with CD-2 Engine Detailer (wait 10 with the hood close), then buff off excess.

Yeah what he said, no strong water pressure. I use a orange cleaner made by STP. I spray a litle water to loosen things up then spray on orange cleaner leave for like 2-3 min then lightly rinse off and then I wipe off the excess water with towels. Then I usually detail my car and after that I will usualyy leave my hood up if possible inside my garage for a few hrs to help any water I couldn't reach evaporate. I haven't had any problems with that method never tripped any sensors or anything. Just be careful and keep the spray away from the wiring harness whenever ossible. Also be careful if you have an aftermarket intake not to get your filter wet.

 

Thanks for the help. Where can I get that cd2 engine detailer? thanks

 

what about Simple green? I heard people use it for the engine. I got some but don't know what to do to clean it. I'm afraid of messing something up, anyone have a DIY???

 

just put a publix bag on the air filter so that no water gets in the intake and you should be ok

 

To state that an engine compartment and components are weatherproof because they are in semi-open environment is a naive excuse for steam or high pressure washing (usually used to get the job done quickly as opposed to safely). The electrical and other engine components are made to be water repellent (very different from waterproof) providing the water is from a low pressure source; i.e. water migration from going through a puddle of water.

•Remove any excess debris, leaves and etc from the hood, grille or air-vent openings
•Spray electrical connectors with a water deterrent (WD40) which repels moisture (avoid spraying on belts)
•Use cling-film or Saran wrap elastic covers to cover any sensors, electrical black boxes, electrical devises that could cause an electrical short-circuits if subjected to water spray.
•This will not guarantee that you won’t cause a problem when cleaning an engine bay but it will greatly reduce the risks.
•Start and run the engine to get it warm, not hot, this will enable the de-greaser to work more efficiently on a warm surface

 

Heres a pretty informative article regarding this topic.....I was planning on using a low pressure power washer my wife bought for small odd jobs around the house, but now I think I stick with a stream of water from the hose.....
