So heres story, last weekend i took my car up to a track in calabogie, Ontario for a 2 day racing school (damn it was fun). Anyways, while i was racing, my car was overheating and i was leaking antifreeze. With further inspection, we deemed it was the radiator. I took out the old radiator wednesday and installed a new one yesterday. After installing it, about 30 minutes later i notice temperature gauge going about up about 3/4 way. I couldn't figure out what it was. The rad is still going through antifreeze like crazy and you can tell there is a leak somewhere still as there is antifreeze all on the top of the skidplate. Meanwhile, today, im driving home from the gf's house, and i stop at a stop sign and when taking off, i notice that it sounded like my exhaust sound got amplified by like 10 times. i pull off to the side of the road and look underneath the car to the surprise of the front pipe breaking off just before the catalytic converter (gotta get new headers ) I was wondering if anyone had any ideas about why there is still an antifreeze leak? It seems as if it is leaking right underneath the radiator, however i just replaced it :dunno:
