I have a Kubota KX161-3 which overheats in a relatively short time when in use.
I have replaced the coolant and installed a new thermostat and 2 x new temperature sensors.
The temperature is showing on the instrument gauge but it is only approx 1/8 of full scale ie. not really showing as hot. It is only after I turn off the engine that I gear the overflow bottle tube bubbling away.
Can anyone offer an explanation of:
- why is it boiling so quickly but not showing on the gauge.
- how can I diagnose/fix it
