Cooling System-Older B series

[kcoburn]

Did all the small older B series tractors use the thermo-siphon coolant circulation system, or were the later ones equipped with water pumps? If they changed, when?

I don't know the answers to your questions, but my 1995 B7100 had the thermo-siphon system while my 1999 B2710 did not.

Neither of your tractors are the syphon system and the last of them went with the 200 series ie, B7200 if I'm not mistaken.
