#4 of 5 Cooling System Issue by pmenendez Nov 16, 2008 (6:59 pm)
I have a 2000 Lincoln Navigator and receintly replaced the upper, lower radiator hoses. I also flushed the system with new coolant and replaced the thermostat. After all that I hoticed that the heater core was leaking, I went ahead and replaced that too. Now I notice that when I turn on the heater it blows hot air most of the time. Sometimes it blows out cold air. I have no leaks and the temp gauge stays in the middle range. The coolant is full. Was I supposed to bleed the cooling system? If so how do I do that with this truck. I did not see any bleed valves near the thermostat housing. CAN SOMEONE PLEASE HELP!!!!

I have a similar problem, for some reason, I can't get any hot air out of my heater. Please help, I'm freezing my rear end off!
