* Thermostat housing gasket: This is the most common location for the upper radiator hose. The hose connects to the thermostat housing, and a gasket seals the connection between the housing and the engine block.
* Engine block gasket (water outlet gasket): The lower radiator hose usually connects directly to the engine block at the water outlet. A gasket seals this connection. Sometimes this is integrated into the water outlet itself.
It's important to note that the exact terminology and type of gasket may vary slightly based on the make, model, and year of the vehicle. A repair manual specific to your vehicle will provide the most accurate information.
