1995 GMC SONOMA Engine And Engine Coolingengine Problems

MECHANIC STATED THIS FAILURE VERY COMMON W/2.2L ENGINES, GMC REFUSES TO ACKNOWLEDGE MATERIAL DEFECT. *AK DIMS 11 IVOQ ENTRY POSTED AFTER 12/12/02 CUT-OVER TO ARTEMIS----------750776.

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

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
