The heater tube on the lower intake that goes back to the inlet/outlet of the heater core on my lower is frozen! I need to get it off. Is there a rubber o ring in it where it threads into the front of the lower? reason I ask is I am about to use some torch heat on it.
There is a thread someplace here about how to replace that o ring, moot point if you're replacing the tube but if just swapping to another intake could be helpful
