[TR] Further Thoughts on Cooling

[Greg Lemon]

The TR4-6 range seems to cool pretty well, at least in my experience.  But as stated the various conditions have a lot to do with it too, condition and tune of the motor, condition of the radiator, crud built up in the motor.   My TR250, with higher compression and a mild cam, doesn't go beyond the the middle of the gauge even on hot days, it still has the original radiator, which I just reversed flushed out when I restored the car.  My TR4A ran pretty cool as well, other British cars I have owned have run towards the hotter part of the gauge (Sprites, MGBs, Austin Healey) but none of them were in new condition  when I got them and I never replaced the radiator on any of them.

I have had no cooling problems with any of my British cars - and where I live (Tucson) summer temperatures can be 'in the teens'.


I think it depends on many factors: engine condition, history, modifications, timing, even driving habits.  What I don't think is that it is random chance or inevitable.

  Regarding cooling:  Is it just TR3s or is this a problem across the
  range?  If so, I'm the odd man out.  1975 TR6, August in Georgia, and
  all I did was flush everything with a garden hose a few years ago.
  Gauge never goes over halfway, not burping, etc.

   These things must have cooled when new, or there wouldn't be so many of them...
