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.
