[Mgs] Cooling issue

[Matthew Milkevitch]

Fellow Listers;
   
  I have a cooling issue with my '74 MGB-GT, and I was wondering if anyone had any input as to the cause.
   
  The basic problem is this: The past couple of days have been fairly hot here in Philadelphia.  Running my BGT with a 165 deg F thermostat, the car seems to run a little hot (in my opinion).  The needle on the temp gauge is a little above the "N."  When I sit in traffic, the temp goes up some more, maybe 1/2 way between "N" and "H."  It comes down a little when I get going.
   
  Recently, I drained the radiator, had it cleaned out and checked....and I re-installed it with fresh hoses (one was leaking some) and a new thermostat.
   
  Today, it was in the low 80's in Phila...very dry and nice.  I ran the car and it pretty much did the same thing!
   
  Any insights?  I have yet to check the water pump.  The temp sender could also be suspect.
   
   
  Thanks for all your help,

  Today's weather in Philadelphia was in the low 80's with low humidity (quite a nice day).
