My montana enginge temp was running way too cool, so we replaced the thermostat, then noticed antifreeze leaking. We changed the water pump, and now the heat doesn't work. PLEASE HELP!!!???

I think you may have air in the heater system and you need to bleed the air from the system. You may be able to bleed the air at the heater hose connections.
