Cleaning the engine compartment???

Quick question...

When degreasing the engine compartment, do I need to worry about any electronic components getting wet or sprayed with high pressure wash?

I know in older vehicles you need to cover the distributor and such, but would I be ok going down to the local car wash and hosing my engine bay down with degreaser and then rinsing it with high pressure spray??

I've done it...I just steered clear of the battery and it's general vicinity (fuse block, etc.)

I have an opinion for ya.......If your truck runs fine then Leave it alone.....It would be really cool to Wash/degrease the Engine Bay and then all of a sudden have issues......I know I might catch a 'lil Flak over this and actually expect some but I dont have to worry about the associated problems that Might come with Jacking around under there......

If you are going to do it, make sure you keep the engine running.. if you turn it off, and wash it, you have a higher chance of it not starting again.

I did mine with just a can of degreaser and regular garden hose pressure . I have heard that high pressure will force thru electrical fittings and seals . flowing water is no more dangerous than driving in the rain . Rob

Yup, I've probably washed my engine bay a dozen or more times since I got my truck a year and a half ago. I use Scubbing Bubbles bathroom cleaner where there's dirt. I let it sit for a minute, then hose it all down.

I'm sorry, I don't like driving with a dirtball under my hood. Fine, if you're a soccer mom, but I'm always looking at something under the hood, and I like to be able to see it and not need a shower after I've handled it.

Amen, and pass the hose!!!!

I did it... at the carwash... with their degreaser and...

she started right back up and purred like a kitten. Drove her on the highway afterwords at 70mph to dry things out.

Came out looking like the day I brought her home from the dealership.

I do like the Scrubbing Bubbles idea, though... I think I'll try that next time.
