2007 620i Overheating Problems

[Combine Pilot]

Hello. I Just recently signed up as a member to this site. I am looking for some assistance troubleshooting as to why the motor continues to overheat? The gator is under much of a load when coolant begins to overflow the reservoir. I have changed out the thermostat and check to see if it had an air lock. It still continues. There is no smell of coolant from the exhaust and I pulled the spark plug to see there was any sign of coolant there.

Any suggestions??
