Had the %#!! thing towed to the BMW dealer in South Bend. The check coolant light came on when my son was driving to judge a debate meet, and after it was over I told him to pour some water into the radiator - it went right through to the ground! I change coolant with Zerex G-05 mixed 50/50 w/distilled water over a month ago, and it's been driven maybe 1K miles since. It checked to 50 below on the hydrometer, but maybe it did freeze.

I'm getting close to getting rid of this truck. It's just one thing after another.
