What hoses connect to a thermostat in town and country Chrysler van?

A Chrysler Town & Country minivan's thermostat doesn't have hoses in the same way a radiator or heater core does. The thermostat itself is a valve *within* a housing. Two larger coolant hoses connect to this housing, not directly to the thermostat itself.

Therefore, you'll find two large coolant hoses connecting to the thermostat housing. One is the inlet hose (from the engine block or radiator), and the other is the outlet hose (to the engine block or radiator). They are usually made of rubber or a similar flexible material. They're relatively thick compared to smaller vacuum or heater hoses.
