[TR] tr3 cooling

[wbeech]

IF you want to keep you TR as original as possible and you can find one,
there was a six-blade fan offered for the TR4s for use in hotter climates.
Moss lists it, 834-010 Tropical Fan, as N/A but they can be found if you are
diligent.  Moss even shows a, 834-880 repro tropical fan but alas it is N/A
as well.

Once you see it and compare it to the 4-blade TR3 fan it will become
apparent that it should move 2x the air.  I have a picture of mine,
available off-list on request.  At present this stands to be the only
non-TR3 part on my restoration.

I am anticipating that winter will eventually end and would like to get some
work done on my TR3A. TS75434L has a tendency to run just a little hot, even
up in the cool mountains of northern new mexico. I imagine the original
radiator is getting a little tired, but I would like to avoid replacing it
for a while longer. It looks like I have two options to help out the
underperforming radiator:

1. The original fan doesn't seem to do the best job drawing air in. Moss
sells a conversion kit that fits the much-improved six bladed yellow fan.
Cost: $240

2. Remove fan altogether and go electric. My guess is this will get the most
airflow going. But will I miss the old fan and rush of air sound? I feel
like I might be taking something away from the car by removing the fan.
Cost: Less than $200.

Well, there might be an option 3: rebuild the water pump with a high flow
impeller. Is this worth it?

I'm not running any additives in the coolant (aside from anitfreeze). Is
water wetter or any other additive worth it to help the system cool a little
better?
