Luke Warm Heat Issue
I found the issue with the low antifreeze: intake manifold gasket! $700 later and no more leaks. Now though I think in the process of the job, a air blockage was created. With the engine running, the upper radiator hose is hot to the touch. As you look at the fire wall, the heater hose on the left is hotter than the one on the right. I think it is flowing but it is hard to tell. The heater setting (I have a Climate Control System) on high and it gets luke warm at best. Could there be a blockage (air or otherwise)? Thanks for the advice/input.
Thanks for coming back and letting us know what you found.
The heater core lines should be pretty darn close to the same temperature even with the heat on high. If they aren't, you still have a restriction in the core and need to flush it out using the instructions on the link I posted up near the top of the thread.
