Alright the Temp gauge moves to middle of the gauge after the car heats up. However I still have no or minimal heat.
I obviously though that the heater core is clogged. Nope, I was able to run a pretty good stream of water through it with really no resistance. The valve is working and is open. The only thing I can think of is that the temp gauge is 'wrong', and the thermostat is stuck open. It's a 3sge, and I did a lot of wire/dash ripping, but I dont think that has anythin to do with it. Removed the AC core, but I built ducting from the blower after I relocated it. Air is blowing out of the vents. Its my understanding that all the air passes through the heater core to the front vents no matter what. The heat is controlled by the valve in the engine bay. -------------------- -93 Rx7, Turbo 6.1L v8, 725rwhp/760rwtq

Same issue happened to me after I changed my waterpump. I thought it was a faulty thermostat at first but it turns out that it had an air bubble. The trick is to bleed the car while having the front jacked up as high as you can. This causes the air in your coolant system to rush to the top much faster than being on a flat surface. I hope that helps!
