dwvoss, do you drive a lot of gravel roads?
Apparently while doing the cooling system work, the mechanic noticed a wet spot on the radiator that he discovered was caused by a crack in the core.
We have family in Iowa, and I debated this last Easter whether to drive the Volt or not because of the large amount of gravel roads we would need to travel. Not so much because of radiator damage, but because of the general damage and rock dust infiltration.
