heater control valve
After the failure of my 409 Smiths heater control valve, I have bypassed it by joining the connecting rubber hoses with a piece of 1/2 tubing. Tested by running around the town and temperatures normal at indicated 90 deg C. Tried to remove faulty valve by disconnecting cable and heater baffle linkages then removing the 2 2BA nuts holding the valve flange to the thin steel bracket attached to the front of the heater box. Valve stuck solid on bracket despite gentle persuasion to break gasket seal with a sharp chisel. Warned not to remove bracket screws as nuts behind inside heater box are not captive. Is there some additional hose connection inside the heater box to the valve? I thought it was like a Jaguar heater valve with just a chamfered face on the rear of the flange sealed with a rubber donut type washer? Any ideas gratefully received. The nearest new valve I could find with what I think are the correct arrangement of coolant connections is for an Austin Healey 3000.
