Larger bore at thermostat end requiring larger clip
GHC811 Radiator end.
This hose has the standard size bore for the radiator but the thermostat end is larger as fitted to the Carb Cooper from 1990/1 and used the old metro type large bore thermostat housing but overflow outlet was left undrilled (housing number
PEQ10019). The Metro drilled oulet was for water to the expansion tank, so this needs to be blanked off when fitting to a Mini without an expansion tank.
