I was driving my friends car when I hit a patch of ice and went into a stop sign... we got it home to find out there was a massive hole in the radiator and the car was over heating fast. It seemed a hose came of the radiator because there was anti freeze everywhere. I have replaced the radiator but there is lots of white smoke that just fills my garage and after about 10 minutes of idle it has serge's, like its trying to stall, but the car is automatic. Any idea!
