I REPLACED THE RADIATOR LAST MONTH WITH A NEW UNIT. MY DAUGHTER DROVE IT FOR A WEEK AND A HALF THEN THE TOP HOSE BLEW OUT. i REPAIRED IT SHE DROVE FOR LESS THAN A WEEK AND THE BOTTOM HOSE BLEW.REPAIRED IT. lESS THAN A WEEK NEW TOP HOSE BLEW. LAST WEEK THE CAR WOULD NOT START . IT TRIED TO. I REPLACED THE PLUGS AND IT HAS RUN FINE UNTILL TONIGHT. (ONLY SEVERAL DAYS)IGOT IT RUNNING AND TOOK IT FOR A DRIVE WHEN I CAME HOME I POPPED THE HOOD AND NOTICED THE UPPER HOSE WAS SWOLLEN AND HARD. THE CAR WOULD NOT STAY RUNNING AND HAD A SULFER SMELL OUT OF EXHAUST. THE SERVICE ENGINE LIGHT WAS ON TOO.
AFTER THE CAR COOLED I CRACKED THE CAP, RELIEVED THE PRESSURE,TIGHTENED THE CAP AND STARTED THE CAR. THE SERVICE ENGINE LIGHT IS STILL ON,IT STARTED HARD BUT STARTED. I AM GOING TO CHANGE THE CAP TOMORROW NIGHT,BUT I'M NOT SURE WHAT IS WRONG.BEFORE I CHANGED THE RADIATOR THE OLD ONE WAS LEAKING BUT I DIDN'T HAVE THE SWELLED HOSE ISSUE.
THANKS
You've got a serious overheating issue creating the pressure. Your temp gauge must be reading hot too.
If not, then you have engine compression pressure getting into the cooling system through a blown head gasket.
Replacing the cap will not help.

Remove the spark plugs and look for a greenish tint on any of them. And spin engine over with plugs out and make sure no antifreeze comes out of any of the cylinders.
