1996 Chevrolet Blazer engine problems

ENGINE

I HAVE A 1996 CHEVY BLAZER 4WD 4.3L CENTRAL PORT FUEL INJECTION. THE #4 FUSE WHICH IS MY GAUGE FUSE KEEPS BLOWING AND WHEN IT BLOWS MY INSTRUMENT CLUSTER ZEROS OUT AND I HAVE NO CLUE WHAT MY SPEED IS WHAT MY RPMS ARE WHAT MY FUEL LEVEL ITS, ETC. MY ALTERNATOR STOPS CHARGING AND MY VEHICAL EVENTUALLY STALLS OUT DUE TO THE BATTERY DRAINING.

ENGINE AND ENGINE COOLING

I PURCHASE MY VEHICLE USED ON 12/4/01 , I HAVE HAD TO REPLACE THE TEMPERATURE GAUGE EVERY YEAR BECAUSE IT INDICATES IT IS OVERHEATING. 3 WEEKS AGO IT STARTED SAYING IT WAS OVERHEATING AND SMOKE FILLED THE INTERIOR OF MY VEHICLE WITH FUMES. IT WAS REPAIRED. AT 3:15 P.M. TODAY, MY CAR INDICATES IT IS OVERHEATING AND NOW THE SERVICE CAR LIGHT IS ON. THIS HAS BEEN AN ONGOING ISSUE WITH THE COOLANT SYSTEM. AS SOON AS I TURN THE CAR ON IT INDICATES IT IS OVERHEATHING. HAPPENING TOO MANY TIMES.

PURCHASED VEHICLE 12/03 SINCE THEN HAVE REPLACED: WATER PUMP 3 TIMES, RADIATOR, THERMOSTAT, LEFT UPPER BALL JOINT, UPPER MANIFOLD GASKET, MAIN REAL SEAL. OVER THE PAST 6-8 MONTHS I HAVE NOTICED THE BRAKING ISSUE SEVERAL TIMES (MORE THAN 10.) LUCKILY NONE WERE EMERGENCY STOPS, HOWEVER WHEN BRAKING DUE TO TRAFFIC LIGHT CHANGE OR STOPPING WHILE GOING DOWNHILL, THE BRAKES "CHATTER," AN AUDIBLE WHINE IS PRODUCED, AND IT IS NECESSARY TO PUMP THE BRAKES BEFORE IT WILL REGAIN PRESSURE AND STOP.

ENGINE AND ENGINE COOLING

OUR BLAZER STARTED OVER HEATING, WE HAD IT FLUSHED DUE TO A MUD LOOKING SLUGE IN THE COOLING SYSTEM AND A NEW THERMOSTAT PUT IN. ABOUT A MONTH LATER IT STARTED OVER HEATING AGAIN. WE AGAIN HAD IT FLUSHED AND ANOTHER NEW THERMOSTAT PUT IN. A FEW WEEKS LATER IT AGAIN OVER HEATED WE HAD IT TOWED IN AND FOUND OUT THAT THIS TIME IT HAD CAUSED THE MOTOR TO BLOW. WE CONTACTED GM THEY SAID IT WAS NOT THEIR PROUBLEM IT WAS DEXCOOL, WE CONTACTED DEXCOOL AND THEY SAID IT WAS GM'S PROUBLEM. WE GOT THE RUN AROUND SO WE CONTACTED THE ATTY GENERALS OFFICE AND FILLED A COMPLAINT WITH THEM.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

THE RADIATOR AND COOLING SYSTEM ON MY 1996 CHEVROLET BALZER GETS RUSTY AND CLOGGED EVERY COUPLE OF YEARS. IN 1998 THE WHOLE RADIATOR WAS TAKEN OUT AND BOILED. IN 2001 THE COOLING SYSTEM WAS FLUSHED AGAIN DUE TO RUST AND CLOGGING. AND NOW, APRIL 2004, THE SYSTEM HAS CLOGGED AGAIN AND CAUSES ENGINE OVERHEAT. GM USES DEX COOL WHICH IS SUPPOSED TO LAST FIVE YEARS, BUT EVERY COUPLE OF YEARS THIS COOLANT SEEMS TO CLOG THE SYSTEM AND REQUIRES AN OVERHAUL COSTING AROUND $400.

I HAVE HAD TO CHANGE THE OIL COOLANT LINES ON MY 1996 S-10 BLAZER 5 TIMES SINCE I HAVE OWNED THE AUTO. I PURCHEASED IT IN 1998. IT WAS STILL UNDER WARRANTY THEN, AND THE FIRST TIME THEY DID THE WORK FREE OF CHARGE. SINCE THEN, EVERY 12-18 MONTHS I FIND OIL DRIPPING IN MY GARAGE, AND I AM TOLD IT IS THESE LINES. I HAVE BEEN TOLD BY 3 DIFFERENT MECHANICS THAT THESE VEHICLES ARE NOTORIOUS FOR THIS PROBLEM. CAN'T ANYTHING BE DONE!!

MY 1996 CHEVROLET BLAZER WITH LESS THAN 53,000 MILES HAS NO HEAT AND STARTED OVERHEATING. I TOOK IT FOR SERVICE AND WAS INFORMED THAT THE DEXCOOL THAT WAS GUARANTEED FOR 100,000 MILES HAD FAILED. THE RADIATOR WAS PARTIALLY BLOCKED AND THE HEATER CORE WAS BLOCKED. BOTH THE RADIATOR AND THE HEATER CORE NEED TO BE REPLACED BECAUSE OF THE SLUDGE AND RUST THAT WAS IN THE COOLING SYSTEM.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

1996 CHEVROLET BLAZER HAS HAD NUMEROUS PROBLEMS WITH COOLING SYSTEM DUE TO BAD ANTI-FREEZE GENERAL MOTORS USED IN THE VEHICLE OF THIS VINTAGE. THEY CHARGED ME TO HAVE THE SYSTEM FLUSHED OUT BECAUSE THE ANTI-FREEZE WOULD CLOG THE HEATER COILS. NO HEATER IN WINTER. PREVIOUSLY THE VEHICLE WAS OVER HEATED AND DEALERSHIP REPLACED THE THERMOSTAT AND WATER PUMP PLUS SEALS AND HEAD GASKET DUE TO THE ENGINE RUNNING TOO HOT. THIS IS THE 4TH TIME I'M RETURNING IT AND NOW THEY WANT ME REPAIR OR REPLACE THE RADIATOR. IT IS STILL RUNNING HOT. IT IS MY UNDERSTANDING FROM TALKING TO THE MECHANICS THAT THIS IS A PROBLEM FOR VEHICLE OF THIS VINTAGE AND IT TOOK A COUPLE OF YEARS FOR GM TO CHANGE ANTI-FREEZE MANUFACTURERS. DO I HAVE ANY RECOURSE? *NLM

I OWN A 1996 CHEVROLET BLAZER WHICH I PURCHASED NEW IN 1996. IT NOW HAS 59,000 MILES ON IT. WE HAVE REGULARLY SCHEDULED MAINTENANCE DONE ON THE CAR, ALONG WITH SCHEDULED OIL CHANGES, CHECKING BELTS, HOSES, ETC. WE ARE CONSTANTLY HAVING OUR BRAKES REPAIRED/REPLACED. LAST YEAR WE NEEDED TO HAVE A BRAKE BOOSTER REPLACED WHICH COST US OVER $700 AND TODAY WE WERE TOLD THAT OUR "ENTIRE" COOLING SYSTEM IS CORRODED...$1,900. AT 59,000 MILES I CERTAINLY DON'T THINK THIS SHOULD HAVE HAPPENED. *NLM

ENGINE AND ENGINE COOLING:COOLING SYSTEM

JUST BROUGHT 96 BLAZERLS WITH 82,000 IN DEC.02. WAS TOLD THAT THE ONLY PROBLEM WAS THEY HAD TO HAVE THE TRANSMISSION REPLACED AT 20,000. WELL,83,000 MILES THE HEATER WAS ON HOT BLOWING WHEN I NOTICED THAT IT TURN COLD AND THE GAGE WENT TO THE RED ZONE. I IMMEDIATELY TURN SWICHES OFF ON THE BLOWER IT WENT BACK TO NORMAL. TWO DAYS LATER IT HAPPEN AGAIN BUT I TURN OFF THE HEATER AND BLOWER COMPLETELY IT WENT BACK TO NORMAL. WE THOUGHT THE TERMOSTACT GOT STUCK AND REPLACED IT . AT THAT TIME WE NOTICE THAT IT WAS GEL UP OVER THE TERMOSTACT, AFTER REPLACING IT , WE TESTED DROVE IT AND IT STILL DID THE SAME THING AGAIN. WE LOOKED AT THE RADIATOR AND FOUND THAT IT WAS GEL UP AND LOOK LIKE RUBBER. WE THEN DECIDED TO CHECK THE FLUID IN THE TRANSMISSION WE NOTICED THAT THE DIPPED STICK WAS RUSTED ON THE OUTSIDE AND WAS RUSTED THE LENGTH OF THE STICK THE FLUID WAS RUSTED. WE WILL NOW HAVE TO FLUSHED THE RADIATOR AND TRANSMISSION. I HAD CHECKED YOUR SITE AND FOUND NO RECALLS OR SERVICE BULLETINS ON THE GELING AND TRANSMISSIONS BEFORE BUYING. TELL TODAY WHEN I DECIDED TO CHECKED OUT COMPLAINTS AND FOUND THAT THERE WAS 54 AND COUPLE WITH THE SAME PROBLEMS OF GELING AND TRANSMISSION PROBLEMS. SO I DECIDED TO CHECK OUT 98 BECAUSE MY SISTERINLAW HAD JUST BROUGHT ONE AND NO RECALLS OR SERVICE BULLETINS BUT THEY ARE COMPALINTS OF COOL HEATING (PROBABLY FROM GELING ANITIFREEZE) AND TRANSMISSIONS BEING REPLACED ONCE ,TWICE AND I GUY 3 TIMES. SO I CHECK 2001 AND THEY WAS SOMEONE ELSE REPLACING A TRANSMISSION. SOMETHING IS VERY WRONG WHEN THERE IS GELING OF ANTIFREEZE FROM 96 TO 98 AND REPLACING TRANSMISSIONS LEFT AND RIGHT SINCE 96. TO ME CHEVROLET HAS A BAD TRANSMISSION PROBLEMS AND GELING PROBLEMS IN THESE BLAZERS GETTING AWAY WITH IT. FROM NOW ON I'LL CHECK OUT COMPLAINTS BEFORE RECALLS OR SERVICE BULLETINS THERE'S THE CONSUMERS EYES AND EARS.
