1958 Case 611 oil problem

[deano1111]

Can anyone please explain how in the world hydraulic oil is getting into the radiator?? Is there some sort of jacket IN the radiator that the hydraulic oil flows thru to cool it?? I’m almost certain it’s hydraulic oil and not motor oil. 1958 Case 611. Case-O-Matic. Thank You.

730-830 Case-o-matics have a cooler in the bottom radiator tank. I bet yours has one too and is leaking. Follow the two lines on the bottom of the engine block that have hoses by the engine crankshaft pulley. They should connect to the bottom of the radiator. Could be repaired or plug the radiator cooler and add an after market air cooler in front of the radiator.

Take your grill screens off and you will see the cooler connections on the lower can of the radiator, this was a common problem with the COM system and back in the day you could buy a new bottom can for the radiator with the cooler installed.

If you elect to do so a aftermarket cooler would maybe get you by BUT the cooler must be able to stand system pressure, not just a cheapy flo thru like an aux cooler for an auto, they are not designed for pressure, just flow.

Thanks for the information. I do see the lines going into the bottom of the radiator. Would this be something advisable…..I only use this tractor to plow snow and maybe 2 hours a week pulling logs out of the woods for firewood. What if the cooler was bypassed and I just made it a closed loop system?? If it’s not advisable I won’t do it. Thanks for the responses.
