    Hello everyone. I was wondering how difficult it is to protect all electronics when power washing your engine? My daughter uses my truck constantly and she lives out in the country which is very dusty. I take it to the detail shop once a month to have the engine power washed but that's getting expensive. I have a power washer that I use here at the house to clean the driveway and other things. I have the 5.3 L engine in this truck. If any of you guys do or have done a power wash on a 5.3L engine,Please let me know on how you do it to keep the sensors,switches,ecm,etc,etec,etc. from getting damaged. If I can do this myself,I will be able to save some money.
    Thanks for all your suggestions or help that I can get from you.

    I avoid power washing an engine at all costs.

    I wash my engines on a regular bases. especially in the spring a clean engine runs cooler.
    on engines with the dist. I take a gallon plastic milk jug , cut the bottom out , slit it up the sides
    to clear the wires and put it over the dist. I also avoid direct shot of water to that area. The
    rest of the connectors etc are all well protected against water infiltration. Going down the
    road in a rainstorm you better believe it gets wet under the hood.

    I use Dawn dishwashing soap and water mix in a spray bottle. Spray it on and let it sit for a bit and then hose it off.

    The risk using a pressure washer on engines or tannys is if there is a seal leaking and if you get to close the pressure will force water through the seal. If you want to clean an engine bay get a good degreaser, spray it on let it set to loosen up all the junk and hose it off, a good degreaser should do most the work and hose wash off the junk. If its too caked on its better to scrape it off then use a degreaser.
