The proper torque is 140-160 lbs foot.
The cooler idea has been thought about for a long time but no one has come up with a cheap way to pump heavy weight gear oil around the system to do it.
Plus heat is a symptom of a problem...one my t-case suffers from while some of them dont...there is an underlying problem, probably bearing clearances hat need adjustment, maybe combined with slop in the internal gears that, if corrected, would be a much better soluton than to run a cooler...treat the condition(s) that is really causing the heat...my opinion...
