well of course...that coolant takes some time to heat up to where the thermostat opens up and the heater core is circulated with coolant...perhaps your t-stat is stuck open...that'd do it~

you could check the temperature at the inlet...in the middle and a the exit to see if the radiator is doing it's job...replace the clogged radiator~

Sounds like the thermostat is sticking. My '93 Caprice was doing the same thing right after I had the cooling system serviced. I had been unlucky and got a defective thermostat. Replaced the thermostat a second time and all was well again. HTH. -Jim
