Oh, tis a long and weary story ...
the upshot is, did not hit anything, they can't find anything that broke, so the only "explanation" is that a snow-dam formed on the front side of the rad, water vapor was pulled through and formed ice on the fan blades which then broke off and were strong enough to puncture the rad core in three locations. The resuting "catasrophic coolant loss" resulted in an overheated and motor, totally cooking one glow plug, partially cooking a second and warping the head gasket. So, since the rad was trashed as the result of FOD, not a warranty item. How convenient - an 11,000 repair on a 9500 tractor - OW!![]()
Dumb question but.... how did the water get through the radiator and on the fan blades and freeze? If the tractor was running the fan would have flung the water off. If stopped the water would have had to build up high enough to cover the fan which means the fan would be froze in place and not turn at all.
Am I missing some thing on how JD built this model? Is the radiator mounted horizontal with the fan below it?
Inquiring mind would like to know.
