After my run up at Moyie Springs my radiator is really clogged with mud.Ive tried washing it out from both directions but it is plugged up good. So the water just goes around the clogged fins.It seems the only way to clean it will be to run some thin piece of metal through all the fins to push all of the dirt out.Any idea what I can use?Normally mud will just wash out but Moyie mud is full of sand so it doesnt want to clean out so easily.Any ideas?

I found out that if I run water through my pressure washer with out it being on,the nossle will restrict the water down so it will have some psi, but not engough to damage the fins.so that seems to be working.Except I need to take the radiator out so I can spray from the back of the radiator.

Compressed air doesnt work?

I have an Idea... Dont know if it will work, but When my RC cars got that way, we cleaned with Rubbing alcohol in a spray bottle and compressed air, it would make sand and dirt fall right out of the head fins.....

 

although this may not work on such a large project....
