The five screw gizmo on the top tank is the pressure/vacuum control. Unfortunately they usually wind up being clogged and not functioning. The main radiator cap is just for fill purposes. I'd much prefer the all brass radiator core if there is a choice.
Steel radiator cores are kind of a trade off, they are more resistant to abrasion but more prone to corrosion.
Old Magnet, do you know if the steel finned rad has steel or brass tubes?....Thanks WA7OPY
During WW2 there was a shortage of Brass so John Deere made all steel radiators with more tubes and fins for their Ag Tractors. Possibly CAT followed suit and did the same thing?
I'm not sure on that one. Time to get out the magnet. My 2T parts tractor lost its radiator to china a long time ago.
I am thinking it was brass tube and steel fins but can't trust my memory.
Well the steel one is tight, the brass one leaks.... I have been told you can not fix the steel one if it goes bad. I am going to use the steel one for now, rebuild the brass one for a spare. After cleaning both rads, the steel one has brass feed tubs and they look very good and quite heavy. There is no sign of rust on the fins, so it most likly a good bet that there is a lot of life left in it. (I hope)....WA7OPY
