“Plastic radior tank cracks. This seems to be an issue with GM vehicles in general. I have talked with several people that have experienced the same problem. Crack seems to start at mounting bolt for radior. I have always owned GM vehicles and currently own 3 however, at the cost of $400.00+ to replace my plastic radior, I may have to reconsider my future purchases.”

(3.8l v6) the work was performed by a firestone retail store in myrtle beach, sc. Has anyone else had this problem and what were the repair costs? I sure am curious.
