My father in law has a tractor that has a 4 cylinder 2.2 liter Kubota engine. The heater in the cab does not heat very much. The heater core temp measures 135 degrees. The temp gauge never gets above 1/3. I covered the radiator and drove it around but the temp never changes. The air that comes out of the vents is not very warm (44 degrees) outside. Does anyone know the temp that these engines shoud run at? I would think that the heater would be able to keep enclosed cab fairly warm. Any ideas?
Thanks,
Bill
