NHTSA Complaint #10086438 — 2002 CHEVROLET TRAILBLAZER

WHILE DRIVING APPOX 50 MPH, GOT HUNG IN TRAFFIC. ALL OF THE SUDDEN MY ENGINE COOLANT HOT WARNING LAMP CAME ON. I PULLED OFF AND HAD TO CALL MY FATHER TO COME GET ME. HE ADDED A SMALL AMOUNT OF WATER TO THE SYSTEM. THE CAR DROVE FINE FOR THE NEXT 10 MILES. AFTER DRIVING AGAIN FOR ABOUT 30 MILES, IT BEGAN TO OVER HEAT AGAIN. PULLED OFF AND LET IT SET FOR ABOUT 30 MINUTES, ONCE AGAIN ADDED A SMALL AMOUNT OF WATER. DROVE FINE FOR THE NEXT COUPLE OF DAYS. MY HUSBAND AND BROTHER FLUSHED THE COOLING SYSTEM AND ADDED DEX-COOL. DROVE FINE FOR A DAY OR SO WHEN IT BEGAN OVERHEATING AGAIN. PARKED THE CAR UNTIL THE FOLLOWING WEEKEND WHEN MY HUSBAND FLUSHED THE COOLING SYSTEM AGAIN. RAN FINE AGAIN FOR A COUPLE OF DAYS. ALL OF THE SUDDEN IT STARTED OVERHEATING AGAIN WHEN I NOTICED THAT IT OCCURED DURING "STOP & GO" TRAFFIC, BUT WHEN MOVING, THE CAR WOULD COOL BACK DOWN. MY HUSBAND THEN REPLACED THE CLUTCH FAN. WORKED FINE FOR ONE DAY WHEN IT BAGAN OVERHEATING AGAIN. TOOK THE CAR LAST WEEK TO A DEALER WHERE THEY CHECKED THE CODE AND IT WAS WRONG, SO THEY ENTERED THE CORRECT CODE. WORKED FINE FOR ONE DAY WHEN IT STARTED OVERHEATING AGAIN. DON'T KNOW WHAT IT WRONG WITH THIS THING!!!*AK
