I just changed my heater core in the truck due to it was busted. When I cut the heater all the way on it wont get hot, even after I drive for hours. There is no leakes. My thermostate that I changed not to long ago opens up properly and when I touch the heater core itself its scortchin! It just dont blow hot!! But when the previous heater core was in, it would almost burn your hand. Why is this? Please help me out!!
