so ive been losing coolant as of late and its been running close to H almost every time i drive so i have to stop every 10-15 miles to fill the coolant which is a real PITA. so i really havent been able to figure out what it was. i thought it may have been a sticking thermo (which is a pita by itself) and that didnt really cure it. so today i see a drip by the draincock screw but it wasnt the draincock screw because it looked like it was actually coming right out of the radiator itself. my questoin is what could possibly cause a radiator to fail at only 43k (wife driven) miles? and if its not the radiator what else could cause it?
