The radiator will then begin cooling the fluid and keep it below the boiling point of about 223° if you use a 50/50 coolant mix. Gluel gasket onto face.place the housing cover back over the radiator thermostat and screw the bolts back on. Once the correct operating temperature is reached, the thermostat will slowly open allowing the fluid through the radiator.
