Where does the thermostat housing meet the radiator?

The thermostat housing is right where the radiator hose meets the engine housing. It looks like half of a metal baseball. When the thermostat becomes stuck, it is reasonable to simply replace it. Also, when the thermostat housing is removed, the housing gasket should be replaced even if you’re just checking it.

What happens if you remove the thermostat on a car?

Removal of the thermostat would have an adverse effect, causing a lowering of cooling efficiency.

Why is the engine thermostat in the closed position?

The flow of coolant does not cycle through the radiator unless it is hot and needs to be cooled. When an engine is cold, the radiator fluid is cold, so the thermostat is in the closed position. When the engine starts up, and the coolant warms.

What happens when the radiator is closed on a car?

When it’s closed, the coolant is blocked until the engine warms up. Engine manufacturers will install a thermostat that opens at the car’s operating temperature (usually either 180 or 212°F, or 82 or 100°C). While the thermostat controls coolant flow, the radiator’s job is to cool the fluid.
