Diagnostics – Testing the Heater Valve on the 1973 Jaguar E Type Series III Coupe

Our restoration technician, Jon, has been working on trying to get the heater valve on the 1973 Jaguar E Type Series III Coupe.

After finally being able to free off the valve, he discovered that this still didn’t fix the issue of the heater being on constantly. For this, Jon has advised that this component be replaced. All other parts of the heating system are working as they should be except the heater valve.

There’s more to come on the 1973 Jaguar E Type Series III Coupe very soon.
