Do I know for a fact, no. That would be an epic fail on my brother's part when he put everything back together after the engine rebuild.

The water that gets to the Vacuum Water valve is 150~160. I just put everything back together after the CLR flush. Which didn't help but I didn't expect it to since water was cycling through the core just fine with my water hose before the flush.

Would the thermostat effect the water flow to the heater core? I'd get that if the water wasn't getting hot enough then you'll get little to no heat but 150~165 seems ample. Right now I just don't think water is getting pushed out of the engine with enough pressure.
