What is your question?
I think the thermostat is stuck in closed position. Or the heater core is clogged.

Need to know what engine you have but, you can try this : https://www.youtube.com/watch?v=HmW0INIEbaU Please give symptoms of the problem you have. If the heater is just not blowing warm air into the van, suspect heater core blockage. If the temp of engine is always on the cold side, suspect thermostat. A little more info. please.
