I did a frame off on my '58 TR3 about 4 years ago while I lived in the San
Francisco bay area. Due to a continuing overheating problem over the 1st
couple of years, I did many of the mod's that you mentioned. I now live in
Scottsdale, AZ and have no problems now!
I kept the stock factory fan and hub as I wanted to keep the crank and crank
hole. This meant a loss of cooling capacity. However, I installed a new
radiator core with better fins and more tubes. I also installed the high
capacity water pump by Ken Gillanders from British Frame and Engine. I
highly recommend that you get one of them! I also fabricated a coolant
overflow system in order to keep the radiator 100% full. I finally added a
12" electric pusher fan mounted up fairly high so that I could still use the
crank. I didn't use a thermostat, but watch the temp gauge and have a manual
No overheating now, even in 105 degree stop and go traffic here in AZ!!
Good luck and as always, NFI and YMMV!

Subject: here's a good question for you folks
As some of you already know, I am in the middle of a restoration project
on my 58 TR3A TS27093, and my question is,
after talking to a few folks about my plan to leave the stub shaft and 4
blade fan off when I install the freshly rebuilt motor.
Will the electric fan (placed in front of the radiator with the nose
shroud) be sufficient to keep the motor cool?
I have the Revington connector pipe with a temp on/off swith that is
threaded into that pipe in order to operate the fan, but I am getting
vibes that I should have a much heavier duty fan, and that it should be
placed on the motor side of the radiator.
The radiator has been re-cored, so I am starting with a sound radiator.
I am also told that there is a 6 blade impellor that I should consider
for the water pump. (by the way where do I get it?)
I would apprecite all of your comments and recommendations. I really
don't want to take the nose off once I put it back on.
And if any of you are going to holler at me let's keep it down, Okay....????
Thanks in advance
PS: this will be the first of numerous questions I'm sure, as I soon (I
hope) begin to SLOWLY put it all back together.
