Broken motor mounts can destroy a fan and radiator in a very short period of time. Especially offroad.
In this case offroad really means a light dirt road up in Roosevelt National Forest that had enough rollover with pits that the front of the engine stayed where it was when the rest of the vehicle came down. Just enough weightless effect to wreak havoc. The fan hit the shroud and exploded.
A piece of the fan split open the radiator about 2 inches down from the top and the spraying commenced. Leaking coolant and running without a fan, the engine temperature rose quite quickly. I shut it down when I saw the temp getting higher and no damage was done by the heat. Luckily for me, I was on a camping trip and was already planning on spending the night.
After towing it back to town, I had the radiator rebuilt by Rocky Mountain Radiator. They did a great job as usual. Coyote Cruisers got me a replacement fan and everything went in quick and easy. The new motor mounts should keep this from happening again for quite a while, not to mention hold the engine where it is supposed to be. The rear mounts were worn thin and a little loose while the front two mounts came out in four pieces. I probably should have seen this one coming.
