    Engine Bay Concern

    Hello!

    My engine bay on my 17GT is getting pretty dusty. I was going to hose it down (power wash) from a distance.

    While looking at it today, I noticed a group of exposed wires on the driverís side behind the headlight. Are those ok to somewhat get wet (obviously not power wash)? Iím not sure how well they will hold up.

    Has anyone else power washed their engine bay? Any problems?

    Engine Bay Concern

    I have never used water to clean a engine bay of any car or truck.

    Your CX5 is still new. What I use is the same stuff I use for the exterior black trim. With a rag, go over all of your plastic covers and anything black plastic inside. I use a SIO2 formula called Gyeon Preserve. There are lots of trim protection products out there.

    As for the wires you could get some shrink tape and seal it up but I don’t think it’s a big problem.

    To clarify, the exposed wires you mentioned are actually insulated and not bare wires. Is that correct?

    Blow off the bay with your air compressor if it bothers you. Ed

    I use the spot-free-rinse "power" wash. My dealership that I worked for powerwashed the shit out of the engine bays all the time. NEVER an issue. Good enough for me (some cars sat on the lot a few months afterwards and were driven once a week or so, nothing manifested).

    Every spring I go over my engine bay... with a wet rag. That's just plain old water.
    Be surprised how effective that can be.

    I use grocery bags and foil to wrap the alternator and wiring. I hose down and use a leaf blower to dry.

    TIP: Dry out the battery tie down bar immediately. Standing water rusts it.... OR just avoid the Battery getting wet.

    My biggest concern is the headlight LEd wiring. I have always power washed cars with HIDís, so I guess that would be worse since they have ballasts.
