Using this turbocharger is quite straightforward. First, make sure your vehicle is the 2017 - 2019 GM with a L5P 6.6L Duramax engine. Since it's a direct replacement, you can simply take out the old turbocharger and install this new one in its place. Just keep in mind that gaskets are not included, so you'll need to get them separately. For maintenance, it's a good idea to check the turbocharger regularly for any signs of wear or damage. If you notice any issues, contact the manufacturer as it comes with a 1 - year unlimited mileage warranty. This warranty gives you peace of mind, knowing that you're covered for a full year no matter how many miles you drive.
