50/50 coolant mix i assume? could be a bad thermostat out of the box, its not unheard of. also are you sure its not getting hot? feel the rad hose after you let it run for a while. if its getting hot and its just not showing on the gauge it could just be the temp sensor.

Thanx Justin, but it's not 50/50 coolant, straight antifreeze. Temperature gauge moves and stays normal.Put new radiator in yesterday, before that, heat was fine and hot? I don't have heat inside, but have not checked hoses, my mechanic says there could be air in the line? Is that possible?

How long since replacing the parts and did you bleed all the air out of the cooling system? Are you saying no heat inside of vehicle?

Thermostat, last week. Radiator, yesterday, heater core, 2 years ago, but it sat for a year. Lines have not been bleeded! And correct, no heat inside vehicle.

Ok. You are probably air locked. Bleed air out of cooling system. Once you are sure all the air is out if you still have no heat then feel the hoses going thru the fire wall to heater core. Are both hot? Is one hot and the other not? Are both cold? This will help us figure out what's going on with it. Note vehicle must be at operating temp before checking the heater core hoses.

if you're just not getting heat in the car it could also be the diverter in the airbox that controls how much hot/cold air gets in, could be stuck in the cold position. but bleed it first like tweedie said, then look into it

Good point justin. If both hoses are hot going to the heater core then the problem will most likely be a blend door or blend door actuator motor issue.
