I was doing a high speed run pushing around 9lbs of boost. The radiator exploded and drained of coolant in a mater of seconds and the car overheated before I got a chance to safely pull over. I let it cool down for around 30 minutes and filled it with coolant (before I knew the radiator blew up). It wouldnt start. I checked the spark plugs and there was coolant in there. I finally got it to start and heard really bad knocking. Ive had the car for less then a month and still dont have it payed off. What is the best solution to fixing it?
