Smiths heater control valve

[chris coote]

Odd fault after a wholly satisfactory 280 mile run in warm weather, on returning to my garage steam was arising from bonnet and lots of coolant being spilt. Opening bonnet revealed steam and water spray from side of heater box. Stopped this by selecting hot on cabin heater control. Allowed radiator to cool down before topping up with 1/2 gallon coolant. Restarted engine and noted slight drip from heater control valve. Does anyone know what other cars use this standard looking 3 port valve so that I can source a replacement? In the meantime is there any harm in diconnecting the two hoses to the valve and blanking them off to isolate the valve and heater. I do not need any more heat in the car in summer!!!!
