Hi Dennis; I had exactly the same problem and decided to sort everything in
one fell swoop.
I had the radiator recored with a thicker core and no starter handle hole.
I only did this because I had fitted a gear-reduction starter, which is far
more reliable than the bomb starter I had before. I then added the
upgraded water pump from The Roadster Factory which, in my opinion, is a
fabulous
piece of kit. I also added the TR6 cooling fan conversion, as I didn't want
an electric fan (but beware it requires a TR6 fan from an era of TR6 where
the fan is slightly different and no longer available. I found a used one
from a used British car specialist in PA. The car now runs beautifully
cool, even in hot 30+ degree celsius temperatures. If you have any other
questions, let me know.

All,
Just to got home from Triumphest. Had a great time. Now for the question:
For the first time in 12 years my TR3A overheated on a couple of the grades
going south out of Las Vegas. I finally had to stop in Hesperia for an
hour
to let things cool down. Yes, it was hot, and I was pushing pretty hard,
but it's never been a problem before. I'm imagining that the radiator must
be getting crudded up. It's an original radiator, still with the crank
hole, and was rodded about 10 years ago. I'm thinking it's finally time
to
replace it. My choices are: 1) getting the original re-rodded, 2) having a
local radiator shop install a modern core, or 3) buying a new aluminum
radiator from one of the big three. Keeping the crank hole is not
important
for me; the only use I have had for it was to use the crank when adjusting
the valves (for that it's pretty handy). I have no experience, but have
been told by more than one person that the repro's from the usual suspects
are not, um, exactly great. Is that true?
I know we've already had the copper vs aluminum debate (once or twice), so
I'm not trying to start that discussion here - I'm looking for "been there,
done that" stories. I need some help making up my mind which way to go.
Thanks, Dennis
