Heater problem
1993 Dodge Truck Four Wheel Drive Automatic 160000 miles
----------------------------------------------------------------
When I open the radiator, there is foam in it, and no or very little heat. I have added antifreeze to it. I know its full. I have had this truck since 1996. A year ago I installed a motor from a 1998 Durango. I had heat last winter, but not much this year. I was told there is a way to purge the system, but I dont remeber how to do it. I need help!

Foam is a sign of a blown head gasket, have a block test done, this checks for the presence of exhaust gases in the radiator.
