More Information for GATES 33009
OE Type; 195 Reverse Poppet (2-1/8" x 13/16" x 25/32")
Gates makes several types of thermostats in order to provide the same design as specified by car manufacturers:

- The reverse poppet thermostat opens against the flow of coolant from the water pump. The coolant, under water pump pressure, is used to help the reverse poppet thermostat stay closed when cool to reduce leakage. This type is engineered with a self-cleaning, self-aligning stainless steel valve

- The offset thermostat with jiggle pin valves is equipped with a special valve in the flange, which allows trapped air in the system to escape and permits the venting of air from the system when filling it with coolant
