Car seemed to be running fine until trip up hot dusty mountain. When we stopped at our destination the car overheated and lots lots of fluid water and antifreeze. However, the add levels said none was needed. The radiator problem seems to be handled but the car dies when we turn to take a curve or turn around. Pt cruiser 2006

it is possible that your fuel tank was low, so when the car is on a 90 degree position the fuel moves from the suction pipe or maybe liquids moving around as they create this problem "most problems like this are caused by poor engine power, were you can feel the car engine is running weak due to the high heels" manual cars are better then automatic in high heels like mountains etc. although depends on your car power 3.5 or 4.7 V6 is good, V8 wont be a problem for sure!
