[TR] TR3 Maradyne Heater

[William Brewer]

    A couple of years ago I installed a Maradyne heater in my TR3A. It was 
designed for a farm tractor, but fit in the TR. I got the idea from HVDA who did 
the same. It has worked very well compared to the original TR3A heater or a 
Triumph Spitfire core that I was using before the Maradyne. Anyway, we just had 
our second snow here in Tehachapi and the heater is blowing cold air. I checked 
the valve on top of the head and when the car is running, water is going through 
there. I gently blew the heater core out with a garden hose and it looks clear. 
What could be downstream from this that would block the coolant from going 
through the core? The car is running a 185 thermostat and getting up to 
temperature. I have the radiator part way blocked off to try to keep the heat in 
the engine compartment. The hose feeding the heater core is warm (not hot) and 
the hose leaving the core is cold.
     The last communication I had from FT was that he told me he had a heater in 
his TR that would burn you out of the cockpit it worked so well. I wonder what 
he had. I wonder what happened to his TR, does anyone know?
     Man, I am tired of trying to stay warm in a TR. Driving it to work 
tomorrow, bundled up.
     TIA,
