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.
