Here's my "radiator" story Wreckerman...
In 2000 after I got my M1009 back from IL (and after drinking a 12 pack with the little lady), I tell her: "Let's go four-wheeling". She climbs in and I proceed to drive into my field knocking down 1-3" dia trees. My CUCV knocked everything down except for the larger trees which took backing up and charging "at ramming speed"...
All was fine and I was laughing so hard, I could barely see to drive. After coming out of my field, I do a u-turn and go back in the way I came. Came out the other end (starting point) and parked the CUCV to drink a few more. I look over from where I'm sitting and see liquid streaming out under the front. I walked over to the front and discover I pierced the radiator with a piece of tree branch and broke the plastic grill in a couple of places (pieces still in place).
The radiator repair cost me $250.00 for that 10 mins of "fun"...
Moral of the story: don't drive back on trails of knocked down trees AND think about NOT four-wheeling after drinking adult beverages...
