Cooling problems

image.jpg Zigs,
I just got over heating problems,my 440/6pack was overflowing on hot days,in traffic,PISSING ME OFF! So I posted problem and a host of suggestions, (I was thankful) I went this route, new water pump, still the same running 220, checked radiator (same 220) radiator fine, I changed thermostat to factory specs 195(for six pack) same then I finally changed CAP!! To a new 16ib, it holds water now ENOUGH TO COOL!! 180 on hway on hot days in traffic 190-210. Good for now! But I WILL BE GOING WITH A CHAMPION RADIATOR! 26" ( MIne is stock 26")
A LOT GOOD HELP HERE!!! GREAT GUYS!!
