It replaces 865615Q06, 865615006, 8638766 and 8610491, crosses to Sierra 18-15102, and it ships in a 20 x 25 x 5 cm box.\u003c\/p\u003e\n\n\u003cp\u003eFitment is by serial number, not by year. The 350 MPI Alpha, the 350 MAG MPI and Horizon in Alpha and Bravo trim, the 377 MAG MPI Bravo and the 5.0L MPI all use this belt in their later serial ranges, and the table below gives the break points so you can check yours before ordering.\u003c\/p\u003e\n\n\u003cp\u003eThese belts sit at the front of the engine where the raw water pump throws spray and the alternator loads them every time you come off the throttle. A glazed belt starts squealing on a cold start, then the ribs go glossy and it lets go with no spare on board, which leaves you with no charging and a motor that overheats inside a few minutes.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth
