Thermostat housing components.
Picture shows both the old Cleveland thermostat & the new Mazda truck item for comparison.
The Mazda truck thermostat opens at 85 degrees C.
You can see here the Mazda thermostat has a plunger to its rear, just like the Cleveland item.
When installed in the housing it covers & uncovers the -10 welded on fitting you can see on the housing.
This fitting with matching -10 hose returns hot fluid back to the Flowkooler pump & recirculates through the engine & back to the thermostat housing.
In most driving situations the car stays between 85 & 90 degrees C.
