Thermostat snap ring holds the thermostat in the tractors engine water neck.
On many IH tractors the previous owners may have removed the thermostat and discarded this retainer ring. Over time the groove this ring fits into will become filled with rust and scale. Thoroughly clean the groove with a pick or other pointed tool to allow the ring to seat correctly into the groove securing the thermostat in place.
