[TR] TR3A Overheating

[KingsCreekTrees at aol.com]

Hi Dave;
 
I'm not convinced an electric fan is going to cure the problem. If  
everything is as it should be, then in 85F weather the benefit of an  electric fan 
would be felt only when idling or inching in traffic.
 
Having said all that, I had overheating problems with my TR3A last year. I  
was flushing the cooling system every couple of years and using 50/50  
coolant/water. However, it still ran too hot when at 60mph in hot weather. Fine  
at 50mph, though, and too hot in traffic. I tried different thermostats and 
all  sorts of adjustments.
 
I finally gave up and put on every cooling system modification I could  
think of: Thicker radiator with no starting handle hole, upgraded TRF water  
pump, TR6 fan conversion (which I prefer over the electric fan conversion). I  
don't know which one of those things cured it, or maybe it was a 
combination of  both, but now the thing will warm up only in hot weather!
 
I know you said the engine was rebuilt but could the water pump  be weak or 
was it renewed?

During  the current spell of 85F + weather recently I took my recently 
rebuilt 3A  out for its first experience of hot weather. It duly duly 
proceeded to  stall whenever I let the revs drop too low when pulling. 
I had to let it  sit and cool for five or ten minutes each time before 
it would start  again.

I assume this was due to overheating (temp gauge was  showing 200F), 
and my next move has to involve installing an electric  fan?
