1995 GMC SONOMA Engine And Engine Cooling Problems

CONSUMERS STATES THE VEHICLE HAD A MAJOR FAILURE TO OCCUR WITH THE CYLINDER HEAD. GMC HAS DECLINED TO RESPOND TO CONSUMERS INQUIRIES. CONSUMER HAS ALL THE PARTS AND WOULD LIKE REIMBURSEMENT FOR THE METAL FAILURE. *JG

CYLENDER HEAD CRACKED, CAUSING LEAKING. DEALER WAS NOTIFIED.*AK

WHILE TRAVELING ON HIGHWAY AND WITHOUT PRIOR WARNING, HOSE FLIPPED OFF THAT WAS CONECTED WITH ENGINE COMPARTMENT. DEALERSHIP WAS AWARE OF PROBLEM. *AK CONSUMER STATED THAT BY THE TIME HE GOT THE VEHICLE STOPPED, ALL THE OIL HAD DRAINED OUT, CAUSING THE ENGINE TO FREEZE UP. *SLC

THE REMOTE OIL FILTER ADAPTER ON THIS VEHICLE IS MADE OF ALUMINUM AND THE MOUNTING BOLTS ARE STEEL. ANY KID THAT PASSES SCIENCE CLASS CAN TELL YOU THAT THESE TWO METALS TOGETHER WILL CAUSE A BI-METALLIC REACTION THAT WILL SEVERELY AND QUICKLY CORRODE THE ALUMINUM, WHICH IT HAS. THIS CORROSION HAS CAUSED THE MOUNTING HOLES ON THE ADAPTER TO FLAKE OFF AND NOW ONLY A SMALL PORTION OF THE MOUNTING BOLT/NUT IS HOLDING THE ASSEMBLY. EVENTUALLY, THE MOUNT WILL COMPLETELY FAIL AND THE ADAPTER MAY FALL INTO SOME MOVING ENGINE PART OR ONTO THE ROAD. THIS COULD SEVER THE OIL FILTER HOSES AND POSSIBLY SPRAY OIL ON THE HOT ENGINE WHICH IS A FIRE RISK. THIS OIL FILTER ADAPTER SHOULD BE MADE OUT OF MATERIALS THAT ARE COMPATIBLE AND WILL NOT CORRODE FROM BI-METALLIC REACTION.*AK

THE HEAD GASKET OF THE ENGINE HAS BLOWN OUT CAUSING A COOLENT LEAK ON THE BACK SIDE OF THE ENGINE. THE MECHANIC AT THE LOCAL DEALERSHIP HAS MADE THE STATEMENT THAT HE HAS SEEN 5 OR 6 OTHER VEHICLES WITH THE SAME ENGINE HAVE THE SAME PROBLEM WITH THE HEAD GASKET BLOWING OUT. THE LEAK STARTED OFF SMALL BUT HAS GOTTEN PROGRESSIVELY WORSE OVER THE LAST FOUR MONTHS. IF THIS IS TRUE AT ALL THE OTHER DEALERSHIPS, THIS SEEMS TO BE A HIGH FAILURE RATE FOR THIS TYPE OF ENGINE. *AK

COOLING SYSTEM FAN BELT HAS A LOT OF PLAY IN IT, AND ENGINE HEAD GASKET HAS BEEN LEAKING FOR TWO YEARS. BOTH PROBLEMS FIXED UNDER WARRANTY. *AK *ML
