Did you properly bleed the air out?

This^, our cars are notoriously known to be a total pain in the azz to bleed all of the air out.

^ agree as well. Lifting the car up to keep it in the air and repeatedly bleeding. It took me some time the last night I had to do it. But with patience and a spill free funnel would definitely help (not fun with a regular funnel and a big air bubble comes up)

Thanks for responding guys.
So I removed the bleeder screw from the back. I opened the radiator cap filled it with fluid. I did not jack up the front end though. can you guys walk me through the bleed process.
Spill free funnel? where do i get one of those?

Not sure. I didn't use a spill free funnel. I thought I did.

You can get one at Pep Boys, Advance Auto, etc...

Basically, you leak the funnel screwed in place of the radiator with coolant in it. You Rev the engine a few times and you'll see air bubbles come out. Squeeze both hoses also and feel them every so often and they should be somewhat comparable in temperature. You do this with the heater on as well to allow the coolant to flow through the heater core.

It takes about an hour to do everything. Usually, I'll still have cold air inside the cabin and after I know the engine is circulating the coolant pretty well. I'll button everything up and take the car out for a fast drive down a road. That will get rid of the remaining air bubbles in the heater core; then carry around a small thing of coolant for a few days as any residual air works itself out.

Ok, so I've got the funnel. My upper hose is hot, lower hose is not. Car has been running with the heat on for about 15 mins. Temp is firmly in the middle of the gauge

The antifreeze in the system appears to be bubbling/boiling. The temp gauge just went from the middle to just below hot. All of this happened after I put the radiator cap back on.

Did you feel the hoses and both hot? Your thermostat should have opened up at some point.

Doesn't sound like your thermostat is opening. You can tey taking it out and putting it in boiling water. Make sure you didn't get a new "bad" one. Try squeezing both hoses too in case there is an air bubble.

Radiator cap?, Proper coolant?,
air bubble?
Water pump?
Anything blocking air flow?
