[TR] Uprated water pump question

[KingsCreekTrees at aol.com]

Hi everyone;
 
Has anyone used the Moss uprated water pump (835-071) on a sidescreen TR? I 
 have to take the front apron off in order to fix a rattly timing chain, so 
I've  got a bad case of "while it's apart-itis". I'm moderately happy with 
the car's  cooling, although it does have a tendency to lose it's temper in 
traffic. With  the three Stags I've owned in the past, I upgraded to a 
12-vane water pump and  the benefit was immense. I've heard talk, though, that 
increasing the flow (if  that's what the upgraded Moss pump does) might not be 
a good thing on a  TR3A, less chance for the fan to cool the coolant.
 
I'm also going to renew or re-core the radiator to eliminate the starting  
handle hole, as I have the gear-reduction starter motor, so that should  
help.
 
Second question (hot topic, this one...): Has anyone fitted the Moss TR6  
fan conversion? My understanding is that the stock fan/fan extension is a  
harmonic balancer and should not be removed. Also, I think I heard talk a few  
years ago that the TR6 fan has to be mounted backwards to make it work. Is 
that  right? I see that part is not in the Moss instructions.
 
Would love to hear some opinions on these two points.
