My son decided to take his Silverado on a little joy ride through what appears to be some pretty thin mud. There is a thin layer of clay/sandy mud covering every inch of the motor. It'* on every fluid reservoir, electrical connection and component. I honestly don't know where to start with this. Should I bring it to the dealership to disassemble and clean everything individually or can I just pressure was the whole thing? Needless to say, it'* my truck now either way, but I have to get this taken care of. Thanks in advance.

It should be fine. Does it have a problem?

You can power wash it. Just use common sense, Is it running OK?
