Jonn has fitted a new diaphragm to the heater valve on our 1964 Ford Zephyr 4 and reassembled it. He then fitted a new seal to the valve connection to the heater rad and fit the valve to the heater.
He rebuilt the heater box and refitted it to the car. After connecting the pipes and cables, Jonn tested its operation, and all was ok.
He went on to vacuum-fill the system but it wouldn’t hold a vacuum. He found a dash leak from the radiator matrix so the coolant was drained and the radiator was removed for repair.
