hi i have a devon van that overheats no oil in water and no water in the oil even compression on all cylinders i have flushed the rad and engine all i can think of is the waterpump the bearings are ok but how can i check the flow
thermostat is 78 degree and works in boiling water am i missing something
Although you might have flushed the radiator – this is no guarantee that the radiator is working efficiently.
If the radiator has not been recored to your knowledge in the last 10 years then is it more than likely silted up beyond reasonable repair. Get the radiator rebuilder to use an enhanced higher capacity core. The company that the club used to use is GAT radiators in Brierley Hill.
Also check your ignition timing – if it is too far advanced then the engine will overheat. Also if the carb is sent too lean.
However it is more than likely to be a blocked radiator. Even fully blocked radiators will run clear water.
Also you should be using a 74 degree thermostat – available through he club.
Thanks for the reply have sent a email to GAT about cost
timing my Devon has always been a bit hit and miss it has electronic ignition so no points there are no marks on the front of the engine my method has been to get the engine running and then turn the dizzy to get the best result
