1998 CHEVROLET SILVERADO Engine And Engine Cooling Problems

DT*: THE CONTACT STATED WHILE APPLYING BRAKE PRESSURE AT LOW SPEEDS THE ANTI-LOCK BRAKES ACTIVATE, WHICH MADE THE VEHICLE DIFFICULT TO STOP. THIS OCCURRED INTERMITTENTLY ON DRY ROADS DURING NORMAL BRAKING WITHOUT WARNING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT REPAIR SHOP. THE MECHANIC REPLACED THE FRONT BRAKE PADS, WHICH DID NOT REMEDY THE PROBLEM. THE DEALERSHIP AND MANUFACTURER WERE NOT ALERTED. THE MECHANIC INSTALLED A SERPENTINE BELT. UPDATED 03/09/06. *JB

1998 CHEVROLET SILVERADO PICK-UP HAD WHAT APPEARED TO BE RADIATOR LEAK. AFTER FURTHER DIAGNOSIS, WHAT WAS ACTUALLY THE PROBLEM WAS THAT THE FITTING IN THE INTAKE MANIFOLD USED TO CONNECT THE COOLANT HOSE WAS MADE OF A DIFFERENT METAL THAN THE INTAKE MANIFOLD; THE PART CRUMBLED WHILE TRYING TO FIT THE COOLANT HOSE OVER THE FITTING BY HAND (NO TOOLS INVOLVED!). I NOW HAVE A TRUCK IN THE GARAGE THAT I CANNOT DRIVE UNTIL IT IS FIXED BECAUSE THE PART DOES NOT "FIT" DUE TO THE CORROSION WHERE THE DISSIMILAR METALS CAME INTO CONTACT AND CORRODED. THE "NECK" OF THE PART IS STILL CORRODED ON THE MANIFOLD AND A NEW PART CANNOT BE INSTALLED UNTIL THE CORRODED METAL/FITTING IS CLEANED OUT. CORRODED PART IS AVAILABLE. DIGITAL PHOTO OF CORROSION AVAILABLE. CORROSION NOT YET REPAIRED. *JB

INTAKE MANIFOLD LEAKED COOLANT ONTO THE ENGINE. THIS CAN RESULT IN THE ENGINE OVERHEATING AND RESULT IN A FIRE.*AK THE FITTING IN THE INTAKE MANIFOLD USED TO CONNECT THE COOLANT HOSE WAS MADE OF A DIFFERENT METAL THAN THE INTAKE MANIFOLD ITSELF. THIS CAUSED DISSIMILAR METAL CORROSION IN THE FITTING ITSELF WHICH LEAD TO UNNOTICED PIN HOLE LEAKS IN THE COOLING SYSTEM. CONSUMER FELT GM SHOULD HAVE PROVIDED A BARRIER BETWEEN THE TWO METALS TO SOLVE THE PROBLEM. *PH *JB

I HAVE A 1998 CHEVY SILVERADO 4X4 1 TON PICKUP. I WAS HAVING TERRIBLE OVER HEATING PROBLEMS, SUDDENLY WHILE ON THE HIGHWAY ONE DAY AND I STOPPED AND OPENED THE RADIATOR IT LOOKED LIKE BLACK SLUDGE. AFTER TAKING IT TO BE FIXED I FIND IT IS THE COOLANT THAT CHEVY INSTALLS CALLED DEXCOOL AND IT IS CAUSING ALL KINDS OF PROBLEMS FOR MOST CHEVY CONSUMERS. WHAT CAN WE DO? I HAVE TO HAVE A NEW ENGINE AFTER THEY EMPTIED OUT 1/2 GALLON OF THE SLUDGE FROM MY VEHICLE. THANK YOU, AND I LOOK FORWARD TO HEARING FROM YOU, [XXX]. *JB INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
