3 cyl diesel running hot according to the gauge. I replaced the sender and that made no difference. Gauge starts out cold and as the tractor warms up it slowly goes to all the way to
super hot. I ran the tractor for 15 minutes and held my breath. It is not boiling and when I shut it off I was able to remove the radiator cap. Where was a little pressure but it was
not boiling. Started it back up and it seems to be circulating. Although, when I squeezed the top hose I could not feel water moving in it. Top of radiator is hot and the bottom is
noticeably cooler. Tractor is running fine and doesn't appear to be running hot. Water pump is turning freely and is not making noise or leaking.
I would replace the thermostat but I don't see how, without removing the radiator. Is that the best way to get to the water pump and thermostat. It was a chore just changing the
sender.
If I can find a candy thermometer I am going to check the oil temperature. What should it be if the engine is running/cooling properly? Is there something else I can do to check the
block temperature? If I opened the block drain by the starter, there should be water purging out of it while running. If there is no water draining, that would mean the block had
boiled dry. I just hate to look at that gauge and not know it the tractor is really hot or not.
