“TL* THE CONTACT OWNS A 2000 OLDSMOBILE SILHOUETTE. THE CONTACT STATED THAT THE VEHICLE WAS SEVERELY OVER HEATING MAKING IT IMPOSSIBLE TO DRIVE.

“I WAS NO THE FREEWAY AND THERE IS A LOT OF CONSTRUCTION SO THERE IS NO WHERE TO PULL OVER THE CAR GOT REALLY HOT. I WAS TRYING TO GET OFF THE FREEWAY AS I WAS GOING ON THE OFF RAMP THE CAR TEMP ALL THE SUDDEN WENT RED THEN ENGINE HAD STOPPED. I HAD MY GIRLS IN THE CAR. THEY WHERE VERY SCARED. COME TO FIND OUT THE HEAD GASKET WENT OUT FOR THE SECOND TIME. IT WENT OUT JUST AFTER I BOUGHT THE CAR IT WAS AT 41000 MILE NOW AT 120000 IT GOES OUT AGAIN IT IS NOW GOING TO COST ME ANOTHER $1700 TO FIX IT. I HAVE READ A LOT OF COMPLAINTS ABOUT THIS PROBLEM WHY HAVE YOU NOT LOOK IN TO THIS PROBLEM. IS IT A SAFETY PROBLEM THESE CAR HEAT UP INSTEADLY AN THE ENGINE HAS A FAIL SAFE THAT SHUTS IT OFF. IF IT WOULD HAVE SHUT OFF A FEW MOMENTS EARLIER I WOULD HAVE STILL BEEN ON THE FREEWAY AND I WOULD HAVE BEEN HIT. *TR”

“2000 OLDS SILHOUETTE 1 OWNER WITH 43000 MILES, INTAKE MANIFOLD LEAKING COOLANT, HAD TO HAVE IT REPLACED BEFORE COOLANT IN OIL DAMAGED ENGINE BEYOND REPAIR, ALSO NOISY LIFTERS.

“WAS TOLD THAT MY INTAKE MANIFOLD GASKET WAS STARTING TO RUST AND WOULD NEED TO BE REPLACED EVENTUALLY. SERVICE DEPT. MGR AT MIDWAY CHEVY IN PLAINWELL, MI TOLD ME HE WOULD KEEP AN EYE ON IT AT EVERY OIL CHANGE (THIS WENT ON FOR AT LEAST 3 MONTHS). MARCH 7TH MY COOLANT LEVEL LOW LIGHT CAME ON. HUSBAND CHECKED THE LEVEL AND THE RESERVOIR WAS EMPTY AND ALL GUMMY IN BOTTOM. SAID IT NEEDED TO BE FLUSHED AND REFILLED. TOOK TO NON-GM DEALER SINCE IT WAS AFTER HOURS AND KNEW THE OWNER WOULD TAKE CARE OF IN MORNING. HE CALLED AND SAID THE MANIFOLD HAD TO BE REPLACED AS THE COOLANT HAD LEAKED INTERNALLY AND EXTERNALLY. THE REPAIR COST WAS $607.00.”
