ok i understand that things do need replacing, but im just trying to figure out this problem, cause the heater core is blocked so i dont know if that might be a reason for the overheating..i bought the car in lakeland and on the way to tampa that night it did not overheat..By now ive replaced the radiator, removed the thermostat, and now the battry cable is starting to melt, and was told this is the reason for the overheating..an electrical problem
