S10 cab won't heat up?
We just had a new thermostat put in the truck and the heater/defroster still blow cold even when engine temperature is 175. Any suggestions?

You have air in the system, take the top off the rad fill to top so level run engine with heater on number one. keep topping up the filler tank while engine is running. after 5 minutes squeeze rad pipes you can reach without touching the moving engine parts when the fan comes on turn off the engine and leave to cool down inside the cab should be nice and warm, when cooled down top up to max line and put cap back on now is done. heater has to be on and on full heat or it will get mist from the system while getting the air out.
