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 !

I don't use anything stronger than the garden hose with spray On a cold engine, I spray the whole area with Dow scrubbing bubbles, wait 10 minutes, spray down again, wait a few minutes then spray off with the hose. Engine stays looking new with 150k plus miles.

Spray everything with purple power (or similar) let it sit, then rinse with garden hose. Should look brand new.

And just to add that I use the "Mean Green" heavy duty grease cutter from Sam's, works like a charm
