CageyH Posted May 3, 2019 Share Posted May 3, 2019 I am going to replumb my system slightly, putting the expansion tank back to near it’s original position. Can anybody confirm what size the two coolant hoses that connect to it are?The main coolant hose is of 32mm diameter if I remember correctly.

SM25T Posted May 3, 2019 Share Posted May 3, 2019 But the hose from the thermostat housing to the heater bypass is 16mm one end and a bit bigger the other ! Link to comment Share on other sites More sharing options...
CageyH Posted May 3, 2019 Author Share Posted May 3, 2019 I have just measured an old thermostat housing I have. The bypass entry point is just under 20mm OD. Link to comment Share on other sites More sharing options...
