Excellent call, Doug!   Ballooning the tubes in a radiator will result in 
immediate blocked airflow & overheating, and is not repairable; the core will 
be junk. Copper/brass rads are more fragile than aluminum but it can happen 
to either. It sometimes happens with 23-lb racing rad caps and stronger 
aluminum cores if a head gasket blows just right. The rad cap vent is just not 
large enough to keep pressures below 20 psi. Good luck- J Deryke
