Larger bore thermostat housing, approx 32MM wide(1.250")and has a small outlet pipe which is blanked off (not drilled out). This same housing was used on Metros but the blanked off outlet was drilled out for water to go to the expansion tank. Therefore you could use the
CAM6117 housing but blank off the outlet if ever necessary. Uses
GRH1140 hose for
PEQ10019 housing which is large bore one end and correct size at other end to fit the standard radiator size outlet. This larger bore housing is a useful upgrade in hot climate countries.
