It came way too late
I bought an alternator and they suggested that I should get a belt and tensioner with the alternator, so I did and the alternator came in great time but a month later I got the rest of the order.The mechanic put in the alternator and I didn’t have the others to install so I’m sending them back.The alternator was fantastic I’m very pleased with it and the time it was delivered.
