so when i was out driving and doing doughnuts in a parking lot about 2 weeks ago when it was cold out my car got a little warm. made me concerned b/c mine stays on the cold side. a couple days later i drove my car again and it started to get hotter and hotter so i pulled over and checked coolant and everything. sat there for about 10 mins to cool down and it stayed really cool after with no heater. thermostat was the bad solutions b/c it was stuck open. did boil test and nothing. re placed that and then drove around and my car after about 10 mins of driving sitting at a light my car started to get warm and my heater stopped working. im puzzled on what it could be. not the right mixture of antifreeze? thanks

could have air in the system after the thermostat change.

Whenever you lose hot air blowing from the heater, it means coolant flow thru the heater core stopped. Usually from low coolant or air pocket. I bet your low on coolant right now.
