Two questions regarding 1946 Farmall A. 1) Are all reproduction radiators the same, and, if not, where do I get a quality one?
2) Is it usual for the oil pressure to drop from 60# to approximately 12# when tractor gets to temp?
I'm using 15-40 oil, and kind of expected pressure to be fairly stable, since viscosity increases with temp. I'm thinking radiator may be loaded with scale and not cooling very well, being a thermosyphon system.
