ABSTRACT:
A cooling circuit for an internal combustion engine is disclosed in which the bypass and thermostat assembly includes means to prevent relatively cold coolant entering the thermostat assembly from a bottom hose to impinge upon a temperature sensitive valve actuating means. The bypass and thermostat assembly is therefore unaffected by relatively colder coolant entering the assembly as the temperature sensitive part of the thermostat remains immersed in relatively warm coolant entering the assembly through a bypass hose even when the bypass is closed.
