I agree you will get better precision measuring the temperature with professional tools. But it seems to me all he needs now is a yes/no answer to whether the overheating problem is solved. So in this case the combination of infrared thermometer, warning light not coming on, and observing no boilover, leads to the conclusion that the repair is now completed (by fixing the leaky hose fitting) and he can put the tractor back in service.
Apparently the only problem was low water level. Also, there could have been boiling at spots in the head allowed by the low system pressure and low antifreeze percentage. (boiling at 212* instead of the 240* +/ - which a 30% coolant blend in a pressurized system would allow.)
Anyhow - it looks like the case is solved. :thumbsup:
