I haven't returned it yet, but I will after I get it off the car. I should have bought the Motorcraft one to begin with then I would have my original pulley to use. But instead, I listened to someone else and got a reman chinese one instead for half the cost. I guess you get what you pay for. Although I jost got the Motorcraft one for $163.00 with no core charge. Now I just have to find a pulley that will work.
