Has anyone thought about the radiator cap? That's the vent for the whole sys if spring is weak it won't vent out pressure and draw coolent out of tank when needed. Have system pressure tested and replace cap.

Just to add something to think about countrygirl, being that your truck is an 83', it wouldn't hurt any to install a brand new water pump and radiator. Almost 20 years old and I'd say you definitely got your moneys worth on anything original on your truck. And congratulations by the way! Just think of it as a renovation of your cooling system for the next 20years.
Update for ya guys: my radiator is indeed shot. Being replaced along with expansion tank. Visible signs of lots of debris. I have reciept from previous owner saying water pump was replaced @104k. Was the debris all junk from radiator? All hoses were already replaced a few months ago as they were spongy and bulging. Is there any place else debris could have come from? And does this compromise the longevity of the water pump which now has 44k on it and to my knowledge it was a remanned water pump. Thanks guys!
