The Sierra 18-5974 is a replacement alternator. The one cross reference given is MES 3189M. Its Sierra part number is 18-5974. No amp rating, pulley type or engine fitment is stated, so confirm all three against your existing alternator and engine before fitting it. Only the part number and that single cross reference are available to match.
Our take
Its one stated cross reference is MES 3189M. Check that number against the alternator you are replacing, since amp rating and engine fit are not given here.
