1999 Cadillac Sls

UPON STARTING MY CAR THEIR WAS A BACK-FIRE UNDER THE HOOD. I AGAIN STARTED THE CAR AND DROVE ABOUT TWO MILES TO MY HOME AND PARKED THE CAR IN THE GARAGE. I THEN ENTERED THE HOUSE THROUGH THE GARAGE DOOR AND STARTED LOOKING FOR RECEIPTS FOR CHARGES I MADE AT THE GROCERY STORE AND CHARGES I MADE REFUELING THE CAR. I WAS UNABLE TO FIND THE CHARGES MADE AT THE GAS STATION. I THEN RETURNED TO THE GARAGE TO LOOK IN THE VEHICLE FOR THE RECEIPT. AT THIS TIME I NOTICED SMOKE COMING FROM UNDER THE HOOD OF THE CAR. I OPENED THE HOOD TO FIND THE INSULATION SMOLDERING THAT IS ATTACHED TO THE HOOD OF THE AUTOMOBILE. I THEN GRABBED A SPONGE AND SOAKED IT IN A PAIL OF WATER THAT WAS IN THE SET-TUB LOCATED IN THE GARAGE. I PUT OUT THE FIRE THAT WAS NOW STARTING TO BURN UNDER THE HOOD. I CAN ONLY IMAGINE WHAT MIGHT HAVE HAPPENED IF I DIDN'T LOOK FOR THE RECEIPT AT THAT TIME SEEING AS HOW THE GARAGE IS UNDER THE ROOF OF MY HOME. NOTE: I HAD NOTICED ONCE BEFORE THAT PART OF THE INSULATION HAD BURNED UNDER THE HOOD OF THE CAR. THIS WAS A BURN ABOUT 12 INCHES SQUARE ON THE LEFT SIDE OF THE ENGINE NEAR THE MIDDLE OF THE HOOD. I ALWAYS WONDERED HOW THIS MIGHT HAVE HAPPENED. AT PRESENT THE AREA THAT HAS BURNED IS NOW ABOUT 18 INCHES IN DIAMETER. *TR
