Won't Stay Warm?

so im either an idiot or unlucky, my truck would take a long time to warm up and if i had the heater going and i was stopped or coasting with the clutch in it would cool way down, so i figured it had to the thermostat was stuck open, so i put a new one in and it got worse... so either im unlucky and got a bad thermostat from the parts store, or im missing something

could be the wrong temp thermostat. are you reading actual temp numbers or relying on the gauge?

when my guage reads normal temp, the truck can be anywhere from 175-215F

Usually low coolant will do what you are explaining but since you changed the stat you should be good.

Might try flushing the heater core, may not be getting good flow.
How about the heater hoses, what condition are they in?

the temp is right on the new t-stat the old one said 192 and the new one said 195, how would low coolant prevent the truck from warming up?

Not warming up the engine just getting the warm coolant to the heater. When you are moving an the engine is running at a higher RPM the coolant will flow in the heater hose because the pressure is higher but when you stop, engine idling or coasting the pressure will drop and no coolant will go in the heater.
