M923a2 Overheated/antifreeze and oilunder hood but not mixed

[atomoros]

Took the M923a2 out last evening. Temp went up to 220 degrees about three miles out. Decided to continue the other three miles. Temp went to 240 and pegged. When I stopped it was steaming. Checked under hood showed obvious signs of antifreeze. Steam continued from below belt pulley bottom of engine. Behind passenger side tire mud flap coated in obvious oil. It does not appear that the oil and antifreeze mixed. no obvious oil anywhere else. It was too dark to check it out last night. Heading out today to look at it. Any quick ideas? Oh, and HAPPY FATHERS DAY to everyone.

My air fan actuator went bad, the internal orings. The fan wasn't kicking in. Got hot and one of the piston liners busted allowing coolant into the oil. Now just waiting to drop in a different motor.
