Took my car into the shop got it back and the main hose that connects the radiator to the engine was unhook, there was any anti-freeze in the car, the car was running a little hot after about 10 mile drive look i look and notice that hose unpluged. I plug it back in and fill it with water, then i get and got some g12 and put it in there.. mean while the coolant light is flashing in my dash, not that i have g12 in there it's still over heating, i only put 1 bottle in how ever. and my heat is not working... any ideas? coolant flush? or is something else wrong now?
