    Ok. So the sticker on top of the radiator says don't use water to clean under the hood but I've been powerwashing my (gas) engines for the past 15 years with no repocussions. Any reasons why I can't do the same with my diesel CUCV?? I hate not being able to see the gasket leaks through the dirt buildup.

    Ahh.... torquing on a cup of cofffee with the smell of diesel exhaust on the way to work....humm...way to the deer stand.

    Don't wash the dirt off....you will open all the leaks that have been plugged by the dirt and grime!!! You will have leaks all over the place!!

    By washing my engine off, I got water into my eighth cylinder. When it came time to crank, the rod bent as well as gouging into my crank. We pulled the head and pan and replaced the rod and piston. It ran fine afterwards, and lasted until 300,931 miles at which point we chose to replace it. I recommend avoiding heavy washing.
