2002 CHRYSLER SEBRING COUPE Engine And Engine Coolingcooling System Problems

THE COOLANT IN MY AUTO WAS GONE, WHEN I HAD TO STOP IN TRAFFIC WHEN I SAW SMOKE. LUCKILY, I WAS NEAR 7/11 WHERE I COULD BUT THE PROPER MIX OF COOLANT. THE NEXT MORNING THE COOLANT HAD DISAPPEARED, I CALLED THE DEALERSHIP. ADDED MORE COOLANT WENT TO THE AUTOMOTIVE STORE PURCHASED MORE COOLANT OPENED THE HOOD AND THE COOLANT HAD ONE AGAIN DISAPPEARED...THERE WAS NEVER ANY RESIDUAL ON THE DRIVEWAY PAVEMENT. THE MAN AT THE AUTOMOTIVE STORE LOOK AT THE RADIATOR AND SAID THERE IS YOUR PROBLEM, ITS LEAKING OUT OF THE CRACK, A HAIRLINE CRACK IN RADIATOR, WHICH CAUSED LEAKAGE IN COOLING SYSTEM. I CAUGHT THIS PROBLEM. THE SERVICE DEPARTMENT SAID THESE RADIATORS ALWAYS HAVE PROBLEMS, CRACKING, BRAKING. CHRYSLER KNEW THESE RADIATOR ARE JUNK YET THEY CONTINUE TO INSTALL THEM...THEY ARE PLASTIC, NOT METAL. UNDER THE 100,000 MILEAGE WARRANTY ONLY THE ENGINE IS COVERED. THIS IS RIDICULOUS BECAUSE...
