the heater core was definatley warm
not hot but warm. So the reason im still losing coolant with the heater off could be because a) the heater leaks and b) the valve is not shutting off properly. Is it possible it could be a leaky and faulty valve?..my coolant was dripping right out from the bottom screw holding the heater core in so i guess not. I think i might bypass it untill i get the required replacement parts. To bypass it do you simply block both ends of the inlet and outlet hoses off or do you loop them by joining them with a bit of alloy pipe and a couple of hose clamps?
