JI Case 730

[Jim Kam]

I have a JI Case 730 gasoline tractor and the other day I parked the tractor after running it for maybe 5 to 10 minutes and when I shut it off I noticed that I had antifreeze coming out of the over flow tube, so I picked up some antifreeze and went back out to the farm the next day to investigate the problem and that is where I am stuck.
this tractor has a long radiator neck so the water sits lower so I pulled off the radiator cap and started the tractor and I could see the water slowly rise to the top and over flow and when I have the cap on it flows out the over flow tube and at this point the water is not hot so it"s not over heating.
my question to anyone is where should I be looking for the problem, Cap or Thermostat or where?
please email me back if you can help me find the the cause.
Thank You
Jim

Radiator could be plugged. Water pump is pumping it into the radiator faster that it can flow. Even with the thermostat closed, a small amount of coolant continues to circulate. Might take off lower radiator hose and see how fast the radiator drains.
