1998 Chevrolet Cavalier engine and engine cooling problems

“I HAVE A Z24 AND MY CAR STALLS OUT AND TURNS OFF WHILE DRIVING I HAVE CONTACTED A CHEVY DEALER WHO STATED THAT THE CAVALIER'S DO, BUT MY TYPE OF VEHICLE(Z24) ISN'T AFFECTED. EXPLAINED IT IS AND THEY SHOULD SEE ABOUT THIS. AND I WOULD HAVE TO PAY TO GET THIS FIXED. ALSO, WHEN RESEARCHING THIS INFORMATION ON THE INTERNET I HAVE FOUND MANY OTHER CUSTOMERS WHO HAVE HAD THE SAME PROBLEM AS I WITH MY TYPE OF VEHICLE. WHY WOULD 1 TYPE OF CAR OF THE SAME YEAR HAVE THE PROBLEM AND NOT ALL OF THEM? IT HAS THE SAME COMPONENTS JUST DESIGNED A LITTLE DIFFERENT. *TR”

“EVER SINCE I BOUGHT MY CAR BRAND NEW, I HAVE HAD ISSUES WITH THE ENGINE STALLING ON HILLS OR INCLINES. MY CAR WILL START TO FEEL AS IF IT'S GOING TO STALL, AND THE RPM'S JUMP UP AS IF I AM ACCELERATING THE GAS, BUT SINCE THIS NORMALLY ONLY HAPPENS ON HILLS, WHEN I APPLY THE BRAKES, MY CAR WILL NOT STOP, B/C THE RPM'S ARE STILL HIGH, THEN THAT'S WHEN THE CAR STALLS, AND OF COURSE MY STEERING WHEEL LOCKS, AND I CANNOT STOP WITHOUT USING THE E-BRAKE, OR PUT IT BACK INTO NEUTRAL AND RESTART IT. I HAVE NO WARRANTY LEFT SINCE IT HAS EXPIRED, HOWEVER, I HAD TAKEN MY VEHICLE TO THE DEALERSHIP AND THEY ALWAYS SAID NOTHING WAS WRONG. I HAVE SMALL CHILDREN, AND IT'S NOT FAIR THAT THIS DEFECT HAS "SLIPPED" THROUGH THE CRACKS FOR THIS LONG. SOMETHING MUST BE DONE BEFORE OWNERS OF THIS CAR GET INJURED OR KILLED! I AM ALSO HAVING A RACK AND PINION PROBLEM, BUT GMAC SAID THAT MY CAR DIDN'T COME FROM THE PLANT WITH THE DEFECTIVE PARTS! WELL, I THINK IT DID. MY CAR HAS BEEN UNRELIABLE MORE OFTEN THAN NOT. EVERY TIME I HAVE DRIVE DOWN A HILL, I SAY A PRAYER. THIS HAPPENS ABOUT 2-3 TIMES/WEEK. MY STEERING IS SO BAD FROM THE DEFECTIVE RACK AND PINION, THAT I CAN'T TURN MY STEERING…”

“1998 CAVALIER CHECK ENGINE LIGHT ILLUMINATED. *TS THE VEHICLE WAS TAKEN TO THE DEALER TO DETERMINE WHAT WAS CAUSING THE CHECK ENGINE LIGHT TO ILLUMINATE. THE DIAGNOSTIC TEST DETERMINED THAT THE EGR VALVE WAS STICKING AND NEEDED TO BE REPLACED. THE EGR VALVE FAILED AT 142,673 MILES AND AGAIN AT 175,055. WHEN THE CONSUMER LOOKED AT THE SERVICE INVOICE IT STATED THAT THERE WAS A LIFETIME WARRANTY ON THE EGR VALVE. THE CONSUMER REQUESTED REIMBURSEMENT FROM THE MANUFACTURER SINCE THE PART HAD A LIFETIME WARRANTY. *NM”

“DT*: THE CONTACT STATED WHILE DRIVING 25 MPH, THE ENGINE STALLED WITHOUT WARNING. THE VEHICLE WAS TOWED TO THE DEALER FOR INSPECTION; HOWEVER, THE PROBLEM COULD NOT BE DUPLICATED.”

“PATTERN OF OVERHEATING AND VEHICLE FAILURES IN 98 CAVALIERS. A SECOND CAR WITH THE SAME PROBLEMS IS NOW BEING REVIEWED RIGHT NEXT TO MINE AT FOX CHEVROLET TIMONIUM. 410-667-6666. CAR WITH 100,049 MILES OVERHEATED FOR FIRST TIME AFTER ORDINARY FLUSH AND FILL 2 DAYS PRIOR. (THE SERPENTINE BELT AND AN OIL CHANGE WERE ALSO PERFORMED FOLLOWING A COMPLAINT OF SMELLING ANTIFREEZE NO OTHER EVIDENCE OF ANY COOLING PROBLEMS) FOLLOWING THE OVERHEATING, THE CAR WAS PROMPTLY PULLED OVER WITHIN 2 MILES AND FLATBEDDED BACK TO THE SERVICE STATION. AFTER REPLACING THE THERMOSTAT AND WATER PUMP (SIGNS OF LOW COOLANT FLOW - TEMPERATURE DIFFERENTIAL IN THE UPPER AND LOWER HOSES) CAR CONTINUED TO OVERHEAT. THE CAR WAS FLATBEDDED TO THE DEALER: NO LEAKS OR DAMAGE WERE FOUND IN THE HEATER CORE, RADIATOR, HEAD GASKET, OR CYLINDER HEAD. DEALER CONCLUSION IS THAT THERE ARE MICRO CRACKS INSIDE THE ENGINE BECAUSE ENGINE GASES ARE MIXING WITH THE ANTIFREEZE, ALTHOUGH OIL IS NOT ENTERING THE COOLING SYSTEM. DEALER INSISTS ONLY POSSIBLE REPAIR IS AN ENTIRE ENGINE REPLACEMENT.”

“WHILE DRIVING THE CONSUMER SAW SMOKE COMING FROM UNDER THE HOOD. THE CONSUMER STATED THAT PROBLEM WAS PERTAINING TO THE ANTIFREEZE LEAKING. THE DEALERSHIP WAS NOTIFIED, BUT DID NOT RESOLVE THE PROBLEM. PLEASE PROVIDE MORE INFORMATION. *NM”
