Morgan has radiator transfusion

Revived in the cooling department ready for the road and slightly lighter at the front end, my preferred conveyance is sporting a nice new aluminium radiator. Mulfab are to be saluted for producing a superior quality piece of kit that arrived on my doorstep on Tuesday as promised, very carefully parcelled up, complete with all necessary nuts, bolts, brackets and hoses.
Re-filled with the red, anti-corrosion coolant, newly greased up sliding pillars and a wash and brush up. With the forecast set fair I feel a gentle drive across Dartmoor the best option after an initial warm up over Haldon Moor.
Not a difficult task, with a rating of about two spanners.

Fan shroud no longer required

Uprated radiator has about 15% greater area

No mesh added behind grill as yet

All up and running again - Road tested -  Jubilee clips tighted - Anti-freeze topped up.

Taking temperature reading from top to bottom of the radiator after a run, the bottom 1/4 is quite cold indicating the thermostat is sipping  coolant through well within the capacity of the radiator to supply. The  metal return tube across and behind the radiator also stays cold.

Morgan 4/4 Radiator failure

Heading towards Newton Abbot yesterday and on the way home from Coombe Cellars the coolant temperature suddenly began to rise cresting the hill by Centrax. A quick inspection revealed the top hose into the radiator had become detached. Fortunately an emergency lash up was possible and water top-up made at the garage, only a short distance down the hill.

The gentle drive home made to keep water temperature as low as possible so as not to raise pressure. The filler cap was also left loose so as not to allow pressure to blow off the temporary lashing. 

Reason for the fracture occuring in the first place seems to be the fact that the radiator is part moulded in plastic. A part prone to vibration, heat and pressure should be of more robust material but others have also reported radiator failures in their Morgans. An issue of quality control perhaps.

A new aluminium radiator from Mulfab will hopefully be fitted next week in time for more motoring while the weather is still kind.
