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...

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...

SMOKE AND RADIATOR FUMES POURING FROM THE DEFROST AND AIR CONDITIONER VENTS.SO MUCH CONDENSATION ON WINDSHIELD MAKES VISIBILITY DIFFICULT.
