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.
