2000 Chevrolet Blazer Engine Problems

ALWAYS SMELL FUEL WHILE DRIVING REPLACED ALL FUEL SYSTEMS THEN ALL SENSORS NEEDED REPLACING SO I DID THAT AND NOW THERE TELLING ME I HAVE A ELECTRIC PROBLEMS SINCE BUYING THIS VEHICLE NEW I PUT OVER 6000.00 DOLLARS INTO AND I STILL HAVE ALL THE SAME PROBLEMS MOSTLY WITH THE FUEL SYSTEM I STILL SMELL ALOT OF FUEL WHEN DRIVING AND BACK FIRING AND SHUTTING OFF IN THE MIDDLE OF DRIVING I HAVE ALL MY RECEIPTS FROM WORK DONE ON THE WHOLE FUEL SYSTEM AND I'VE LOOKED UP THIS KIND OF BLAZER AND EVERYONE WHO OWNED ONE HAS THE SAME PROBLEMS. *TR

HAD THE HEATER CORE FIXED THREE TIMES UNDER WARRANTY AND IT IS OUT AGAIN. *TR

THE HEATER CORE HAS GONE OUT FOUR TIMES SINCE I HAVE OWNED THE VEHICLE WHEN THIS HAPPENS I CAN NOT SEE OUT MY WINDSHIELD AND I AM BREATHING IN POISONOUS FUMES FROM THE ANTI FREEZE THAT IS NOW LEAKING INTO THE DRIVERS CAB. *TR

I HAVE A 2000 BLAZER LT WITH 128,000 MILES THAT HAS HAD HEATING/COOLING SYSTEM PROBLEMS FOR SEVERAL YEARS. HAD DEX-COOL IN SYSTEM WHICH I MONITORED REGULARLY TO MAKE SURE HAS TOPPED UP. GM STATES DEX-COOL IS MAINT FREE TO 155,000 MILES. WHEN VEHICLE REACHED 100,000 MILES, I BEGAN TO LOOSE HEAT. I NOTICED A CRYSTAL-LIKE RESIDUE FLOATING IN COOLANT. DRAINED, BACK FLUSHED HEATER CORE AND FLUSHED SYSTEM 3 TIMES THEN ADDED PRESTONE (GREEN) COOLANT. AFTER ABOUT 10,000 MILES BEGAN TO LOOSE HEAT AGAIN, REPEATED FLUSH AND FILL. EVERY YEAR SINCE, WHEN COLDER WEATHER SETS IN, THE SAME PROBLEM SHOWS UP AND I GO THROUGH THE SAME FLUSH AND FILL PROCEDURE. DEX-COOL HAS LEFT SO MUCH SLUDGE THROUGHOUT THE SYSTEM I CAN'T GET IT ALL OUT AND IT CONTINUES TO PLUG THE SYSTEM. I HAVE REPLACED TWO WATER PUMPS, THREE THERMOSTATS AND HAVE SPENT HUNDREDS OF DOLLARS JUST DOING FLUSH AND FILLS. ENGINE TEMP WILL BE GOOD FOR THE FIRST FEW WEEKS AFTER A F & F THEN BEGINS TO RUN HOT AGAIN WITH THE SMELL OF COOLANT IN AND AROUND THE VEHICLE. THERE ARE NO VISIBLE LEAKS ON THE GROUND OR ON THE BLOCK. ALL ENGINE VACUUMS CHECK OK. ALL OTHER REGULAR MAINT DONE WHEN REQUIRED. LAST F & F DONE 08-30-2009 AND VEHICLE IS STARTING TO RUN HOT ALREADY/AGAIN. *TR

TOOK VEHICLE IN FOR OIL CHANGE, NEXT DAY CAR MADE NOISES AND LEAKED OIL. CONTACTED DEALER, TWO DAYS LATER CAR NEEDED TWO QTS OF OIL. CAR DEALER THEN TOWED CAR,HAD CAR FOR A WEEK AND SAID 'IT'S NOT THEIR FAULT'. EXTENDED WARRANTY EXPIRED. *TR

INTAKE MANIFOLD IS LEAKING WHICH CAUSES OVERHEATING. I'VE OWNED TWO 2000 CHEVY BLAZERS AND HAVE HAD THE SAME PROBLEM IN EACH. *TR

BLAZER SEEPING OIL FROM OIL PAN, WILL NOT FIX ONLY IF I PAY 75% DUE TO 90 DAY WARRANTY,AND TOLD IF THEY WOULD FIX IT I WOULD ONLY CREATE MORE PROBLEMS, IT WAS ALSO TOLD BY DEALER AND CHEVY THAT IT IS NORMAL FOR YEAR AND MILEAGE, I DON'T THINK SO WITH 47,000 MILES, WHEN I OWNED A 97 CHEVY WITH 97,000 MILES , NO LEAKS BUT SALESMAN KNEW OF IT 3 WEEKS AFTER PURCHASE WHEN 30 DAY BUMPER TO BUMPER EXISTED,WAS AT DEALERSHIP JULY 6, 2006 FOR ALL ITEMS BUT CHEVY NOR DEALERSHIP DOCUMENTED IT OR THE GREASE FITTINGS, LUBE, CHECK FLUID LEVELS LIKE WAS SUPPOSE TO DO, SALESMAN CHECKED FLUIDS FOR ME AFTER THEY NEGLECTED TO DO THEIR JOB.. SO CHEVY SAYS CAN'T GO BY SALESMAN BECAUSE HE NO LONGER WORKS THERE, SEEPING OIL FROM OIL PAN IS NOT NORMAL, I DIDN'T RECEIVE A ODOMETER PAPER ON IT OR MY TRADE IN.. I FEEL THEY ARE DOING ME WRONG AND CHEVY IS BACKING THEM UP, I EVEN GAVE SALESMAN NUMBER AND TOLD THEM I HAVE A NOTE PAD HERE OF ALL THAT WAS TO BE DONE WITH PAGES AFTER ON NOTE PAD WRITTEN ON AFTER THAT DAY AND THEY WON'T LISTEN. THEY NEVER GAVE ME CORRECT MILEAGE ON IT WHEN I PURCHASED THE VEHICLE. *JB

PO410 CODE FOR EMISSIONS SYSTEM - SECONDARY AIR PUMP I HAVE HAD THE CAR 5 YEARS. HAVE REPLACED 2 SECONDARY AIR PUMPS ON EMISSIONS SYSTEM AT CONSIDERABLE COST. BOTH CORRODED FROM WATER ENTRY. KNOWN COMMON PROBLEM ON BLAZERS. *NM

ACCELERATOR STICKING. FROM STANDING START, ACCELERATORS PEDAL REQUIRES CONSIDERABLE PRESSURE TO MOVE FROM RESTING POSITION. AS PEDAL IS DEPRESSED, VEHICLE JUMPS FORWARD BEFORE OPERATOR CAN REMOVE PRESSURE. COMPLAINTS TO DEALER RESULTED IN THE ESTIMATE OF A $100.00 CHARGE TO CLEAN CARBON FROM THROTTLE BODY AND APPLY A CHEMICAL TREATMENT TO HELP PREVENT FURTHER STICKING. THIS SHOULD NOT BE A MAINTENANCE ITEM AS IT COULD RESULT IN UNCONTROLLED ACCELERATION, POSSIBLE LOSS OF CONTROL, AND ACCIDENT. DEALER DIAGNOSIS WAS ALMOST INSTANTANEOUS SO THE PROBLEM MUST BE A COMMON ONE.*NM

MY 2000 BLAZER LS ZR2 HAS 68000 MILES ON IT. AROUND NOVEMBER 2005, WHEN I NEEDED MY HEATER IN THE MORNINGS, I NOTICED THAT IT WOULD NOT BLOW ANY HOT AIR. I HAVE HAD THE COOLING SYSTEM FLUSHED AND REPLACED THE THERMOSTAT AND STILL HAVE NO HEAT. I CAN SMELL COOLANT EVERY NOW AND THEN WHILE I AM DRIVING. SO, I AM LED TO BELIEVE THAT MY HEATER CORE IS LEAKING AND OR BLOCKED. I HAVE DONE SOME SEARCHING AROUND THE INTERNET AND HAVE NOTICED THAT THIS IS A COMMON PROBLEM WITH BLAZER'S AND IT IS CAUSED BY THE DEX-COOL COOLING FORMING A "SLUDGE" IN THE COOLING SYSTEM. I FEEL THAT GM SHOULD BE RESPONSIBLE FOR MY REPAIRS, AS THEY HAVE KNOWN OF THIS ISSUE FOR YEARS, YET STILL CONTINUE TO MANUFACTURE VEHICLES WITH THIS TYPE OF COOLANT ANYHOW. *NM

PROBLEM WITH THE DEX-COOL SYSTEM IN MY 2000 CHEV BLAZER---HEATER WENT OUT JULY 2004, WAS UNDER EXTENDED WARRANTY AND HEATER CORE REPLACED, RADIATOR WAS FLUSHED AT THE SAME TIME. ONE YEAR LATER VEHICLE OVER-HEATING AGAIN, NO LONGER UNDER EXT WARRANTY...PAID $212 FOR THE FLUSH TODAY AND FILED COMPLAINT W/ GM DUE TO THE OBVIOUS PROBLEM WHICH THEY DENY WITH DEX-COOL ( 8 STATES HAVE CLASS-ACTION SUITS). WAS TOLD BY GM REP THAT THE COOLANT SYSTEM IS A MAINTAINENCE ITEM AND THEY COULD NOT ASSIST OR ACCEPT RESPONSIBILITY IN THE REAPAIR COST. SPOKE WITH THE GM DEALERSHIP WHO ARGUED MY CASE, ASKED WHAT MAINTAINENCE REQUIRED ON MY PART, SINCE THE DEX-COOL MAINT SCHEDULE IS 155K MILES, MAINT FREE---MY VEHICLE HAS 70K MILES AND SECOND FLUSH IN 12 MO PERIOD. WAS TOLD BY DEALERSHIP THAT NOTHING I COULD REALLY DO TO MAINTAIN, JUST KEEP CHECK ON COOLANT LEVEL EVERY OIL CHANGE, AND SYSTEM COULD FAIL AGAIN AT ANY TIME--NO GUARANTEEE AND THE DEALERSHIP ALSO ARGUED WITH GM REP---THAT THERE IS A PROBLEM WITH DEX-COOL ANTIFREEZE.......I PAID THE COST, BUT AFTER PURCHASING GM PRODUCTS FOR THE PAST 30 YEARS, IF I AM FACED WITH ADDITIONAL COST OF AN APPARENT DEFECT BY THE MANUFACTURER...I WILL GO TO ANOTHER MAKE OF CAR---THANK YOU FOR YOUR TIME

ANOTHER OF OUR GENERAL MOTORS FLEET HAS AN INTAKE GASKET LEAK. THIS IS FOUR WITHIN A YEAR ON SEPARATE CHEVROLET OR GMC VEHICLES. ALL HAVE A 4.3 L ENGINE, AND ALL ARE 1994 THROUGH 2001 MODEL YEARS. ALL HAVE BETWEEN 75,000 AND 120,000 MILES. ALL HAVE THE FACTORY TYPE COOLANT DEXCOOL. *AK

SMOKE AND RADIATOR FUMES POURING FROM THE DEFROST AND AIR CONDITIONER VENTS.SO MUCH CONDENSATION ON WINDSHIELD MAKES VISIBILITY DIFFICULT. BREATHING RADIATOR FUMES AND FLUID POSING SERIOUS HEALTH RISK TO MY CHILDREN. SON HAD BEEN SPITTING UP BLOOD AND COMPLAINING OF HAVING DIFFICULTY WITH BREATHING BEFORE WE COULD DETERMINE IT WAS FROM THE VEHICLE ALSO CAUSES THROAT IRRITATION. THERE ARE NO INDICATOR LIGHTS ON AND THE VEHICLE WAS JUST PURCHASED ON 1/3/2005 WITH 100603 MILES.

RUST IN COOLING SYSTEM, WATER PUMP FAILED, REPLACED AND FLUSHED COOLING SYSTEM. HEATER INOPERATIVE, BLOWS COLD AIR. VEHICLE STILL NOT REPAIRED.*AK

2000 CHEVROLET BLAZER 2 DR. 4 WD. OIL LEAKS ON ALL ENGINE OIL COOLANT LINES. FOUR REPAIR SHOPS I CONTACTS INDICATED THEY REPLACE THESE LINES ON LIKE VEHICLES AT LEAST ONCE A WEEK. *JB

TRIVER IS CONSTANTLY PUTTING OIL IN VEHICLE. DRIVER NOTICED A PUDDLE OF OIL UNDER THE CAR. TOOK VEHICLE TO A MECHANIC, AND HE DETERMINED OIL LINES NEEDED TO BE REPLACED. *AK

THE OIL COOLER LINES ARE LEAKING ON MY 2000 BLAZER( WITH ONLY 54,248 MILES). THE MECHANIC WHO CHANGED THE OIL TODAY STATED THAT HE HAS YET TO SERVICE A BLAZER THAT DIDN'T HAVE LEAKING LINES EVENTUALLY. INTERESTING! HE ALSO STATED THAT HE DIDN'T UNDERSTAND WHY THERE HAS NOT BEEN A RECALL. IF THIS IS NOT THE PROPER PLACE TO REPORT THIS, PLEASE LET ME KNOW. PERHAPS YOU CAN ALSO DIRECT ME TO THE CORRECT PLACE. THANK YOU.

OIL LEAKS WHERE OIL LINES CONNECT TO THE REMOTE OIL FILTER. MECHANIC INDICATED THIS WAS A COMMON PROBLEM IN CHEVY SUV/TRUCKS WITH REMOTE OIL FILTER SYSTEMS. *LA

SERVICE ENGINE SOON LIGHT STAYS ON AND IDLES ROUGH SOMETIMES WON'T START. FUEL GUAGE SWINGS BACK AND FORTH NOT REGISTERING THE GAS LEVEL.GOES FROM EMPTY TO FULL.

SEVERE WATER DAMAGE AND MOLD. BOGGING DOWN IN ENGINE WHEN AT COMPLETE STOP THE TRUCK WILL NOT ACCELERATE.*AK
