THIS PART IS CURRENTLY INVOLVED IN CLASS ACTION LAWSUIT IN SAN FRANCISCO IN THE ALAMEDA COUNTY SUPERIOIR COURT. JUDGE MICHAEL BALLACHEY HAS ISSUED A PRELIMINARY DECISION TO ORDER A RECALL ON AS MANY AS 2 MILLION VEHICLES MODEL YEARS 1983-95. UNFORTUNATELY, I COULDN'T WAIT FOR THE RECALL SINCE MY VEHICLE HAD STALLED TWICE IN THE LAST 2 MONTHS. I FELT I HAD TO PAYFOR A ARTIAL CORRECTION (NEW PART RELOCATED IN THE SAME SPACE) AND WAIT OUT THE RESULTS OF THE LAW SUIT. IF A RECALL IS ORDERED AND IF FORD DOESN'T APPEAL, I WILL NEED TO HAVE THE PART RELOCATED TO A DIFFERENT PART OF THE ENGINE SINCE OVERHEATING CAUSES EVENTUAL PART FAILURE. MY MECHANIC DID NOT WANT TO RELOCATE THE PART WITHOUT DIRECTIONS FROM THE FORD MOTOR COMPANY.
