      Radiator leak, not sure the cause.

      For the last couple of months I have had a slow leak in my radiator. Not a big deal since I barely need to drive my car. Well over the last few days it has gotten a lot worse.

      I thought the leak was from some mud I had driven through that had pushed itself up against the bottom of my radiator. But I have been looking without taking the car apart, and this does not seem to be the case. It seems to be coming from behind the fan shroud.

      My question is, has anyone else had the fan shroud damage their radiator? and what are some ideas to prevent this from happening again?

      These things are a bit expensive, and I'd rather not be replacing one every couple of years.

      I will think of a better signature later.

      If the fan shroud damaged it, then I'd inspect the mounting hardware (clips, bolts, etc.) to be sure it's not shifting around in there. That really sounds kinda odd to me. I wonder if the damage could have happened while re-installing the fan.

      Did they get rid of the plastic thermostat housing in the 2008? If yours still does have the plastic one, then the leak could be coming from that, spraying forward and making it look like it's from another source. Probably not the reason for your leak, but thought I should mention it, just in case.

      Thermo is aluminum. Definitely radiator leak, it's wet even behind the fan.

      OK as promised the update on the cause. The leak came from multiple things. Back in august I was in an accident that twisted the front end a little bit. I had the car professionally repaired, but apparently the radiator got twisted a little bit somewhere in the entire process. This caused it to rub against the cooling fan and started a small leak. Carry on to a few months later when I decided to take my car through a little mud into some timber. The mud pit wasn't deep and only the length of a barn, but apparently deep enough for my bottom radiator support to scoop plenty of it up and finish off the radiator. Lesson learned, the Aveo is not a rally racer. Removal and re-installation of the radiator is very easy, just takes a little attention to detail. I will post an update on a few notes I made in the how-to that is on this forum shortly.
