Can anyone tell me the inside diameter of the lower radiator hose on a JD 970 or the od of the lower radiator hose connection? I am needing to get a radiator hose heater for this cold weather and would prefer to have the right size heater when I take it apart to make the install. The OD of the hose looks to be 1 1/2" so I am assuming that the id of the hose is probably 1 1/4".
