Peter - I'd say leave it for now. Just drive the car and prioritize
the most important stuff. It may be beneficial if he gets stuck in
freeway traffic.<br>
<br>
I have a 72 TR6 with just the stock fan. I've had the overflow
bottle vent twice, both in 105 deg plus weather.<br>
<br>
Once was driving up to the Palm Springs tramway. I was stuck behind
a driver going too slow, so the engine was at a lower RPM without
good air flow. I lost about 1/2 inch of coolant from the overflow
bottle.<br>
<br>
The other time was the drive a decade or so ago up to VTR at
Portland, OR. It was 105+ driving up I-5 with the faster traffic.
The temp gauge was staying just above the upper dot at speed, but as
soon as we pulled of near Yreka and I lost airflow, it went up. I
poured some water down the front of the radiator when we stopped and
turned on the heater. Lost a negligible amount of coolant from the
overflow.<br>
<br>
I came close at the Canadian border going to the All Triumph Drive
In in BC back in the 90's, but just turned on the heater and all was
fine to clear the crossing.<br>
<br>
I think these might be the only three times since I got the car
about 1994 that an electric fan would have helped with cooling.<br>

<div>My cousin's son's new to him 1971 TR6, has a pusher fan on
the radiator. The stock fan is still there. I am looking for
opinions on the efficiency of that pusher fan. Does it really
help? Maybe at idle, but does it block at speed? thoughts and
experiences, please.</div>
<div>Thanks to all in advance...</div>
