I have got a 2007 Pontiac G6 Sedan. Last two days ago, I wrongly put the power steering fluid into the engine coolant surge tank which is with the pressure gauge. I started the engine once and as soon as I knew in about few seconds, I stopped the car completely. As my town is small, I can't call car repair to home thus, I need to repair it by myself or drive to repair shop with this problem. Is flushing out the coolant good enough or is there any other procedures that I need to follow?
