Why are the radiators on my truck overheating?
The copper brass radiator can internally corrode and plug themselves up and a condition called solder bloom could cause the tubes to seal shut. Both copper brass and aluminum radiators can also plug up when you add too much stop leak, or while working on the engine you allow gasket material or dirt to enter the cooling system.
