Is it possible for the impeller on the water pump not to be circulating water through the engine cant get any heat you replaced the thermostat its a 1996 gmc vandura 3500?

Yes if the impeller fell off the shaft , the system is clogged, or the thermostat is stuck closed the water will not flow(will probably cause overheating).But if your not getting heat from the heater it is most likely a by pass valve or clogged heater core. If the heater core was leaking it may have been bypassed to avoid leaking water.Could also be something as simple as a vacuum hose/actuator that controls a wind vane that directs air flow towards or away from the heater core.

Water pump not circulating coolant?
If the pump is not circulating coolant insure that the thermostat is not stuck closed. If the thermostat is ok then the pump will have to be replaced.
1989 Mercury Topaz overhearting?
First, check the rad. Was it ever replaced? If it is good, check the thermostat, Does it overheat at idle? or on the road? At idle, most likely the Rad. On the road, could still be the rad. or possible the thermostat. Also, was the water pump ever replaced. That will also cause overheating. As time goes on, the impeller wears, and will not push the water fast enough. Good luck.
Replaced thermostat but cold air and still over heats?
Coolant at proper level? System air bound and needs to be purged? Water pump not circulating coolant? Defective thermostat? Collapsed radiator hose?

I suspect that either your thermostat is plugged with debris from the radiator change or that the thermostat was replaced backwards. The spring side should be towards the block.

Low coolant? System air bound? Hoses collapsing under pressure? Water pump not circulating coolant?
Your ford ranger temperature gauge drops when you turn on the defroster it is a 1991 you have replaced the thermostat and flushed the coolant twice?
The defrost is cooing your coolant by circulating the fluids through the heater core. Check the water pump to insure that its pumping and check the radiator for blockages in the fins. Also check for an air bubble that can happen when a thermostat is replaced.

It's very possible.

Low coolant? Wrong thermostat temperature range? Heater core plugged,restricted or airbound? Water pump not circulating coolant? Temperature control cable not adjusted properly?
Why would a van overheat after changing the thermostat and water pump?
Assuming it did not overheat before you replaced thermostat and water pump you may have installed the thermostat backwards. It is also possible the cooling system wasn't refilled properly and was air bound.
