running too cold

changed to the 180 thermostat..works like a dream, now I can watch the thermometer in the rad cycle between 181 and 176. so I started changing all of the hoses and such.....ah ha.. The stupid little heater core return hose barb was plugged at the water pump (not the 1/2 hose, the other one.)
I'm going to run the prestone rad cleaner through it for a day before putting the new water pump in.. I feel soo stup'd.... on to the next thing..

I HAVE HEAT..just in time to wear shorts :(
