Ford Motorcraft Serpentine belt part number E7UZ-8620-H. According to Ford this replaced the "E7UZ-8620-F" part number and fits 1988-1993 Mustangs with the 5.0L engine. Motorcraft part number is JK6-911. This part was discontinued some time ago and no longer available from Ford. If you are doing an original restoration, then you know original parts make the difference. We were always under the idea that 87-93 used the same belt but we are going by Ford's official parts application listing for this part so it may fit other applications as well. Genuine New old stock original Ford part.
