Too Cool 2120

[wisconsinBill]

My 2120 with Jodale Perry cab ran cool last year. Put in 188 degree thermostat. Added cardboard to front of radiator. Got nice and warm and temp gauge showed "Normal" the past 2 months. Now, yesterday it only shows just above 'cold' on gauge and blows cool air in the cab. How do I get it up to running temp and get heat in cab again? ( I only ran the loader yesterday at low engine rpms and its -5 degrees outside.) Must I run the snowblower at full revs to get heat? Also overflow bottle is still full and thermostat never opened as top hose is cold as is top radiator tank.

Check -n- see if your still full of anti-freeze if not top off . If no external leaks then its leaking internally. Head gasket or????

Thanks for reply, but the fluid level is right up to the top in the radiator tank and also in the overflow bottle after it cools; also when it is hot the overflow tank shows full to the top line.

maybe the fins on the water pump are warn thin. lack off circulation.

Had chance to tractor for snow removal AGAIN ! I reved it up a little more up to near PTO speed and the temp gauge came up to operating temp and the cab heater blew heat out. The only thing I did to "fix" is remove the radiator cap. It seemed to come off normally, but could it the cause of not heating? Could a bad pressure cap cause heating/ cooling problems? According to the forecast, I will be getting more chances to test out the cooling system.
