Thermostat - 160° F fits Case A28114 010716AB fits International 37634DA fits Ford NAA 600 800 2000 4000 fits Allis Chalmers 70228543

Replacement 160-degree thermostat covering an unusually wide cross-section of mid-century American iron — International H and M families, the Allis-Chalmers D-series gas engines, Oliver Super-series, early Case row-crops and crawlers, and Ford NAA and hundred-series engines among others. The 160°F opening point was standard on most gas engines of this era and runs cooler than the 180°F stats common on later diesels; running a higher-rated thermostat can push operating temps into territory the original cooling systems weren't sized for. Standard service item if the engine runs cold, overcools in the field, or the original has stuck open.
