Temp Gage going up
My temp gage keeps raising when in free

Thermostat could be sticking
Checked that already
Check for dirt and bugs blocking the air flow through the A/C and radiator, then check fan operation, if those check good then it is probably the radiator is internally restricted. Back flushing might help, but it's been my experance that you eventually wind up replacing the radiator.
