2002 CHEVROLET TRAILBLAZER Engine And Engine Coolingcooling Systemfan Problems

TL*THE CONTACT OWNS A 2002 CHEVROLET TRAILBLAZER. WHILE DRIVING AT ANY SPEED, THE CONTACT HEARD A LOUD ROARING SOUND COMING FROM THE ENGINE. AFTERWARDS, THE RPM'S WILL INCREASE TO 3 OR 4 AND REMAIN THERE FOR A WHILE BEFORE DECREASING. A MECHANIC STATED THAT THE FAN CLUTCH NEEDED TO BE REPLACED. THE PURCHASE DATE WAS UNKNOWN. THE CURRENT MILEAGE WAS 89,000 AND FAILURE MILEAGE WAS 87,000.

THE ELECTRICAL GAUGES ON OUR 2002 CHEVY TRAILBLAZER DID NOT FUNCTION PROPERLY WHEN THE FAN CLUTCH FAILED, LEADING TO ENGINE OVERHEATING. THE OVERHEATED ENGINE BLEW THE HEAD GASKET BEFORE THE ENGINE ITSELF BLEW UP. MY HUSBAND WAS HAD JUST BACKED OUT OF THE DRIVEWAY AND HAD DRIVEN ABOUT 200 YARDS WHEN THIS HAPPENED. IT IS IMPORTANT TO NOTE THAT WARNING SYSTEMS MALFUNCTIONED: THERE WERE NO LIGHTS, BELLS OR ANY INDICATION THAT COMPLETE ENGINE FAILURE WAS IMMINENT. THERE WASN'T EVEN THE ODOR OF AN OVERHEATED ENGINE. IF THIS HAD HAPPENED ON OUR LOCAL FREEWAY I COULD BE SUING GM OVER MY HUSBAND'S INJURY OR DEATH. *TR

JUST AS MANY OTHER 2002 CHEVY TRAILBLAZER OWNERS HAVE FOUND, ONE DAY THERE WAS A LOUD FAN NOISE WHEN ACCELERATING, REDUCED GAS MILEAGE, AND A LACK OF ABILITY TO ACCELERATE THAT LASTS FOR ABOUT A MILE. AFTER A FEW MINUTES OF SEARCHING ON THE INTERNET IT IS APPARENT THAT MY PROBLEM IS THE FAN CLUTCH, TSB 060602003, NHTSA 10019510. IT APPEARS THAT THOUSANDS OF OWNERS ARE HAVING THE SAME PROBLEMS AND HAVE BEEN FOR YEARS BUT THERE IS STILL NO RECALL. ALTHOUGH THIS PROBLEM IS INTERMITTENT AT THIS TIME IT ALMOST CAUSED A SERIOUS ACCIDENT THE FIRST TIME IT HAPPENED. I WAS MERGING ONTO A HIGHWAY AND COULDN'T GET THE ENGINE OVER 30 MILES PER HOUR. WE WERE NEARLY REAR-ENDED. I HAVE COPIES OF AT LEAST A THOUSAND INTERNET COMPLAINTS WITH THE FIRST ONE POSTED AROUND NOVEMBER 2001 --- JUST ABOUT THE TIME WE PURCHASED THE VEHICLE NEW. (IF YOU...

LOUD ROARING NOISE THAT SOUNDS LIKE A JET PLANE. WAS INTERMITTENT, BUT NOW CONSTANTLY. THE NOISE IS EVEN LOUDER WHEN YOU ACCELERATE. THE FAN IS TURNING AT AN ASTRONOMICAL RATE OF SPEED AND GAS MILEAGE NOW IS ONLY ABOUT 9 MPG. RIGHT BEFORE THIS CONSTANT JET PLANE SOUND STARTED, THE BATTERY BLEW UP. YES, BLEW UP! AND THE TRUCK WOULD DIE IF THE A/C WAS TURNED ON. THE DEALER TOLD ME IT WAS THE WATER PUMP AND THE PULLEY AND BELT ALSO NEED TO BE REPLACED. I HAVE NO IDEA WHAT A WATER PUMP HAS TO DO WITH ANY OF THIS, BUT $711 LATER I STILL HAVE THE PROBLEM. *TR

- 2002 CHEVROLET TRAILBLAZER - TRAILBLAZER ASCENDER COOLING FAN CLUTCH & SPEED SENSOR ASSEMBLY. - LOUD NOISE COMING FROM COOLING FAN. WHILE UNDER WARRANTY WAS TOLD BY DEALER THAT THE NOISE WAS NORMAL AND THAT THERE WERE NO PROBLEMS. AFTER WARRANTY EXPIRED THE FAN CLUTCH FAILED AND WAS THEN TOLD THAT THE NOISE WAS NOT NORMAL AND THAT THIS SUV HAS A MAJOR PROBLEM WITH THE FAN CLUTCH. DEALER STATED THAT EVEN THOUGH THIS IS A PART WITH A VERY HIGH FAILURE RATE IT IS NOT A RECALL ITEM. *JB

I GOT IN THE CAR TO GO TO WORK THE OTHER DAY AND AS SOON AS I PUT THE CAR IN DRIVE AND STEPPED ON THE GAS IT MADE A LOUD FAN NOISE THAT MADE THE CAR SOUND LIKE AN AIRPLANE TAKING OFF. THIS WAS THE FIRST TIME THE CAR HAD EVER MADE THAT NOISE. I DROVE THE CAR AROUND THAT DAY BEFORE GETTING IT TO A MECHANIC. THE MECHANIC SAID IT WAS THE FAN CLUTCH THAT NEEDED TO BE REPLACED. I BELIEVE THEY SAID IT WAS AN ELECTRONIC RELAY, WHICH WAS WHY IT COST $600 TO REPLACE. THE SUV WAS A 2002 MODEL AND HAD 57,500 MILES ON IT.*AK

DOORS RATTLE AND SHIFT WHILE DRIVING DOWN THE ROAD. THE WINDOWS ALSO RATTLE, PARTICULARLY ON THE DRIVERS SIDE, FRONT AND BACK. ALSO, THE AIR/HEAT BLOWER IS STUCK ON #4. IT WON'T BLOW ON ANY OTHER SETTINGS

I HAD THE FAN CLUTCH REPLACED ON MY 02 TRAILBLAZER AT 75,000 MILES. THE CLUTCH FAN STICKING, MAKING A VERY LOUD ROARING NOISE THAT THE DEALERSHIP CALLS NORMAL. THE FAN HAD BEEN DOING THIS VIRTUALLY SINCE NEW PURCHASE, BUT ONLY OCCASIONALLY AND ALWAYS WENT AWAY QUICKLY. NOTHING I COULD DEMONSTRATE TO THE SERVICE DEPARTMENT. UNTIL IT FAILED. *AK

I OWN A 2002 CHEVY TRAILBLAZER AND RECENTLY EXPERIENCED LOUD, ROARING NOISE FROM ENGINE COUPLED WITH REDUCED POWER AND VERY POOR GAS MILEAGE. TOOK THE VEHICLE TO A DEALER AND CONFIRMED THE FAN CLUTCH HAD FAILED. DEALER QUOTE WAS $637.50 TO REPAIR. I ULTIMATELY PURCHASED THE PART ONLINE AND HAD IT INSTALLED BY A LOCAL MECHANIC AND SAVED MYSELF AROUND $260. VEHICLE RUNS FINE NOW. I CANNOT BELIEVE GM HAS NOT ISSUED A RECALL FOR THIS ISSUE. A SIMPLE INTERNET SEARCH WILL RETURN HUNDREDS OF POSTS RELATED TO THE FAN CLUTCH FAILURE. VERY DISAPPOINTING. *NM

DT*: THE CONTACT STATED WHILE PULLING OUT OF THE DRIVEWAY AT 5 MPH, A LOUD NOISE WAS HEARD. THE VEHICLE WAS DRIVEN TO THE DEALER WHO DETERMINED THE COOLING FAN NEEDED TO BE REPLACED.

MY 2002 TRAILBLAZER SOUNDS LIKE A JET ENGINE WHEN PREPARING TO START OUT IN THE DRIVE POSITION AT ALL TIMES NO MATTER WHEN SPEED YOU START OUT IN. THE AUTO MECHANIC I TOOK IT TO SEVERAL TIMES SAID IT WOULD COST HUNDREDS TO REPLACE THE CLUTCH FAN TO SEE IF THIS WOULD FIX THE PROBLEM POSSIBLY MORE AND IT IS USING WAY TOO MUCH GAS NOW. *JB

DT*: THE CONTACT STATED AFTER STARTING THE VEHICLE, THE FAN CLUTCH WOULD NOT DISENGAGE. THE DEALER DETERMINED THE FAN CLUTCH NEEDED TO BE REPLACED. *AK

WHEN I FIRST BOUGHT MY 2002 TRAILBLAZER, THE FAN CLUTCH WOULD OCCASIONALLY BE FULLY ENGAGED WHEN I STARTED THE TRUCK IN THE MORNING. IT USUALLY RESUMED NORMAL FUNCTION WITHIN A MILE OR SO. AS OF YESTERDAY, IT WILL NOT DISENGAGE AND THE CHECK ENGINE LIGHT CAME ON. IT SOUNDS LIKE THE LABOR TO REPLACE THIS CLUTCH IS VERY HIGH. I'M NOT SURE IF I DARE TACKLE THIS MYSELF, BUT THE THOUGHT OF PAYING $700 TO REPLACE SOMETHING THAT SHOULDN'T FAIL AT 47,000 MILES IS DISGUSTING. *NM

2002 CHEVY TRAILBLAZER HAS A SERIOUS FAN CLUTCH PROBLEM. VEHICLE HAS 52,000 MILES. THE CLUTCH FAN STAYS ENGAGED AT ANY SPEED, VEHICLE WILL SUDDENLY LOOSE ACCELERATION AND ALSO GETS POOR GAS MILEAGE. CHECK ENGINE LIGHT EVENTUALLY CAME ON ABOUT 2 WEEKS AFTER THE VEHICLE STATED TO SOUND LIKE A TANK. WILL TAKE THIS TO A LOCAL MECHANIC AS BASED OFF OF THE AMOUNT OF COMPLAINTS ON THE WEB WITH OTHER PEOPLE HAVING THE SAME PROBLEM, AND THE DEALER CHARGING $700.00 TO REPAIR WHEN THE PART CAN ACTUALLY BE PURCHASED LOCALLY FOR $229.00. THERE ARE DEFINITE PROBLEMS WITH THIS AND BASED OFF OF ALL THE OTHER COMPLAINTS GM IS WELL AWARE THAT THERE IS A PROBLEM, AND WILL DO NOTHING ABOUT IT. *JB

OWN 2002 CHEVY TRAILBLAZER WHICH I PURCHASED USED IN MAY 2004 WITH APPROX. 35-37,000 MILES ON IT. DRIVEN ON HIGHWAY 5 DAYS A WEEK 61 MILES ROUND TRIP TO WORK. VEHICLE DEVELOPED LOUD ROARING NOISE, POOR ACCELERATION, INCREASED GAS USAGE WITHIN THE LAST YEAR WHICH INITIALLY WAS OCCASIONAL BUT AS OF YESTERDAY BECAME NON-STOP. SERVICE ENGINE LIGHT CAME ON. NEARLY HIT FROM BEHIND DUE TO INABILITY TO ACCELERATE WHEN MERGING INTO TRAFFIC. DIAGNOSTIC CODE PO495 WHICH ENDED UP BEING FAN CLUTCH. PART AT PARTS STORE WAS 217.99 W/TAX. AFRAID TO TAKE TO DEALERSHIP AS MULTIPLE OTHER OWNERS WITH SAME PROBLEMS PAID $600+ FOR REPAIRS WITH MAJORITY BEING LABOR. FREQUENCY OF FAN CLUTCH PROBLEMS BY OTHER OWNERS MAKES IT APPARENT IT SHOULD HAVE BEEN A RECALL BY GM. *NM

ENGINE FAN NOISY... RUNS TOO FAST/HIGH. A COUPLE MECHANICS HAVE SAID FAN CLUTCH IS THE PROBLEM AND NEEDS TO BE REPLACED. TRANSMISSION DOESN'T SEEM TO SHIFT SMOOTHLY... AND SEEMS TO BE RELATED TO THIS ENGINE FAN SPEED. *NM

THE FAN CLUTCH ON MY '02 TRAILBLAZER IS STARTING TO GO BAD, WITH ENGINE ROARING AT INTERMITTENT TIMES, PER THE DEALER, WHO REFUSES TO WARRANTY IT, EVEN THE VEHICLE HAS LESS THAN 17K ON IT. IT IS OUT OF WARRANTY BY 8 OR SO MONTHS. GM HAS SENT THE WRONG MESSAGE. CALLED CHEVY, THEIR EARS ARE CLOSED ALTHOUGH THEY OFFERED A MAINTENANCE DEAL IF I WOULD SAY I AM SATISFIED. SUCH A DEAL SINCE THEIR SERVICE PRICES ARE SKY-HIGH. UNACCEPTABLE. *JB

FAN CLUTCH TOTALLY FAILED. NO PRIOR WARNING, FAN CLUTCH FAILED CAUSING THE TRAILBLAZER TO LOSE ABILITY TO GAIN SPEED/POWER. *JB

MY 2002 TRAILBLAZER WITH 70,000 (JUST OUTSIDE OF WARRANTY) HAS A BAD FAN CLUTCH. THE DEALER IS TRYING TO CHARGE ME $500 FOR A PART THAT COSTS $230 AT MULTIPLE LOCAL PARTS STORES. MY COMPLAINT, HOWEVER, STEMS FROM THE FACT THAT A 5 MINUTE INTERNET SEARCH YIELDED 8 OTHER TRAILBLAZER OWNERS WHO HAVE HAD THIS EXACT PROBLEM. ALL 8 OF THE CARS HAS LESS THAN 80,000 MILES. THIS IS OBVIOUSLY A PROBLEM THAT GM NEEDS TO REACT TO AND ISSUE AN OPTIONAL RECALL. *JB

THERMOSTATIC-CONTROLLED CLUTCH ON RADIATOR COOLING FAN WAS NOT DISENGAGING AND "SERVICE ENGINE SOON" WARNING LAMP WAS LIGHTED. "ON-STAR" SERVICE PROBE CONFIRMED PROBLEM IN POWER TRAIN/COOLING SYSTEM. DEALER CONFIRMED DEFECTIVE COOLING FAN CLUTCH AND REPLACED FAN CLUTCH ASSEMBLY. THIS IS A SUV THAT RARELY SEES TRAVEL OFF OF PAVED ROADS. ALL SERVICE PERFORMED AT DEALERSHIP. COOLING FAN CLUTCH SHOULD NOT BE FAILING AT 57,520 MILES. "GOODWILL WARRANTY" COVERED MOST OF REPAIR EXPENSE. *JB

4 W/DR LIGHT GOES TO 4HI/ ALL WHEEL DR/4 LOW WITHOUT WARNING AT ANYTIME. THE COMPUTER MODE WAS REPLACED ONCE UNDER WARRANTY AT THE MOMENT IT DOESN'T SEEM TO BE ACTUALLY SHIFTING. ALSO HAD A LOUD JET SOUND COMING FROM THE ENGINE AS IF IT WAS LABORING AND HAD TO HAVE THE FAN CLUTCH ASSEMBLY REPLACED @ A COST OF OVER $800.00 . *JB

1) SINCE OWNING MY 2002 CHEVROLET TRAILBLAZER, ON OCCASION, THE CAR WOULD DRIVE AND SOUND LIKE A SEMI (LOUD AND HEAVY WHEN I ACCELERATED). 2) JULY 19, 2005, WITH 51000+ MILES, THE SUV CONTINUALLY WAS LOUD AND HEAVY WHEN I ACCELERATED. FINALLY, THE ENGINE LIGHT CAME ON. 3) I TOOK IT TO A SHOP AND THE MECHANIC SAID IT WAS THE ELECTRIC FAN CLUTCH AND HE HAD SEEN IT BRAKE DOWN IN SEVERAL TRAILBLAZERS. COST TO REPLACE: $732.33. I STILL HAVE THE OLD PART IF YOU NEED IT.

2002 CHEVROLET TRAIL BLAZER 67180 MILES. FAILED COOLING FAN CLUTCH. WWW.MYCARSTATS.COM INDICATES OTHERS HAVE THE SAME PROBLEM. GM TURNS A BLIND EYE. COST TO REPAIR IS JUST UNDER $600. THE FAN RUNS CONSTANTLY. IT IS A DESIGN FAILURE. I WILL NEVER BUY A GM VEHICLE AGAIN AND I WILL URGE ALL THE PEOPLE I KNOW TO NEVER BUY GM AGAIN.*AK

CLUTCH FAN IS CAUSING VEHICLE TO BE SLUGGISH ON TAKE OFF. MAKES A LOUD ROARING NOISE, BURNS MORE GAS. *JB

THE CLUTCH FAN ON OUR CHEVROLET 2002 TRAILBLAZER WENT OUT AND THE FAN STAYED ON. IT RESULTED IN REDUCED ENGINE POWER BECAUSE THE FAN WAS PULLING SO MUCH POWER FROM THE MOTOR. WHEN OUR MECHANIC CALLED FOR PARTS, THE CHEVROLET DEALERSHIP HAD 15 ON STOCK. APPARENTLY CHEVY IS AWARE OF THIS PROBLEM BUT HAS NOT RECALLED IT.*AK

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...

TWO WEEKS AGO THE CLUTCH FAN ON MY 2002 CHEVROLET TRAILBLAZER ENGAGED BEFORE I LEFT THE HOUSE AND NEVER DISENGAGED ON A 15 MILE TRIP TO AND FROM WORK WITH VARYING SPEEDS (AS LOW AS RESIDENTIAL, AND AS HIGH AS 70 MPH). THIS IS HIGHLY UNUSUAL FOR IT TO 'STICK' IN THE ENGAGED POSITION. USUALLY IT ENGAGES ON A COLD START AND IS OFF WITHIN A MINUTE OR TWO. I WENT SO FAR AS TO TURN OFF THE A/C FIGURING THIS COULD TRIGGER THE COMMAND TO ENGAGE THE COOLING FAN. I CALLED THE DEALER I USUALLY HAVE MY WORK DONE AT, AND THEY JUST SAID TO BRING IT BY. ON THE APPROXIMATE 25 MILE TRIP FROM MY WORKPLACE TO THE DEALER, AT SOME POINT THE FAN DECELERATED FROM THE 100% ENGAGEMENT I HAD BEEN EXPERIENCING FOR TWO DAYS, IT ILLUMINATED THE SERVICE ENGINE SOON (SES) AND THE CRUISE CONTROL FAILED...

TRAILBLAZER SERVICE ENGINE LIGHT ON, ENGINE REVING, SEEMS TO BE FAN CLUTCH STUCK IN HIGH SPEED, CAUSES POOR ACCELERATION, POOR GAS MILEAGE, AND COSTS OVER 500 DOLLARS TO REPAIR. DEALER IN SMALL TOWN STATES THEY HAVE REPLACED SEVERAL IN THE SAME YEAR MODEL TRUCK. DUE TO THE HIGH COST OF THIS REPAIR, I AM FORCED TO DRIVE MY VEHICLE UNTIL I CAN COME UP WITH THE MONEY TO REPAIR IT. HOPEFULLY IT WILL NOT DAMAGE ANY OTHER PARTS IN THE MEAN TIME. THERE SEEM TO BE SEVERAL COMPLAINTS THAT DEAL WITH THIS SAME THING. ALSO, THE REAR BRAKE LIGHTS KEEP GOING OUT .

THE FAN CLUTCH WAS NOT OPERATING PROPERLY WHICH CAUSED THE VEHICLE TO OVERHEAT. PLEASE PROVIDE FURTHER DETAILS. *JB

COOLING FAN HAD INTERMITTENT PROBLEMS OF RACING WHEN YOU STEPPED ON GAS, NOW COOLING FAN IS RACING CONSTANTLY. I HAVE BEEN TOLD BY THE DEALER AND CHEVROLET THAT A NEW PART HAS TO BE DESIGNED. NO ONE KNOWS HOW LONG THIS WILL TAKE. I HAVE BEEN TOLD VEHICLE IS SAFE TO DRIVE, HOWEVER IT CERTAINLY DOES NOT SOUND LIKE IT AND I HAVE BEEN STOPPED BY POLICE THINKING I AM RACING ENGINE OR DRIVING UNSAFELY.*TS *NLM **DIMSII IVOQ ENTRY POSTED AFTER 12-12-02 CUT OVER TO ARTEMIS**770110
