Need to get air out of cooling system on my car

check your catalytic converter, when this thing clogs up it will run but it will start to loose power and sputter.

sounds like thermostat or just air pockets trapped in the cooling system.

I know what the problem is. like my 93 chevry it came disconnected at the handle next to the drivers seat.

Hello and welcome to FixYa!

As a first course of action, I strongly suggest that you have a freon charge and check for leaks. It's just normal that you lose freon specially for a long period of use.

Hope this helps and thank you for using FixYa! Have a good one!

1)Air trapped in system
2)plugged radiator
3)collapsed heater hoses while engine is running
4) heater control valve
5) blend door motor for hot/cold (VERY COMMON)

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Code 12 is just a code telling you that you are in the diagnostic mode and it is working. Code 33 is a mass air flow error code. The computer is detecting mor air going into the engine then required at the detected rpm for more than 5 seconds. Could be caused by a faulty connection(wiring harness,ect) to a bad ECM(electronic control module) or MAF(mass air flow) sensor. Also the TPS(throttle position sensor) could be out of adjustment.

front of engine just about 11:00 over crank pullry

A radiator fan is designed to pull air to pull air through the radiator to help cool it, while blowing the air on back across the engine to try to assist once again at keeping the unit running cool as to not over heat.

if you can check for spark when it wont start and fuel pressure and the service port , would be great information , otherwise pattern failure is ignition module and crank sensor (replace them as a set) , after cools off it will run again.

Drain the system. Remove the upper radiator cover and the dual cooling fans (4 bolts and an electrical connector). Disconnect the transmission cooler lines and the upper and lower hoses.. The radiator should freely pull straight up and out. Reverse the process to install the new radiator.
