70 radiator, low or high pressure

[mdross1]

Starting to order parts for 70 resto wondered what the 70 gas had for radiator cap.Would seem these tractors would run low pressure,what do you pro's have to say.

How about looking on the JD parts list and use the proper cap?

Already know what cap to use was wondering if because these tractors are 60 yrs old had things changed,and the fact that the cores are not all that HD.Just loosening the bolt for the overflow tube support bracket on the bottom tank it started to weep.

The 70 is a pressurized system. Should have 5 to 7 psi.
