Silly question but can you power wash under the hood

[MikeN]

AS the header says,

under my hood my motor is dirty as hell with dust from the dirt roads near my house, can I power wash the shit out of this? or will this cause issues?

 

[ExplorerTom]

I wash mine several times a year.

Expect misfires if you power wash anywhere near the plug wells.

Yes you can, as long as you are careful about not using high pressure around any electrical connections/wiring harnesses..

Just make sure the engine is cold, and focus the spray on the grungy area only, like the engine block, exhaust headers etc...

I do this about every 10K miles or so (on all 5 vehicles) nottaproblemo, keeps 'em lookin real goooood !
