Using this turbocharger is straightforward. First, make sure your vehicle is a 1994 - 1998 Dodge with a 5.9L Cummins engine. Then, replace the old turbocharger with this one following the standard installation steps. When your vehicle is running, the turbocharger will work automatically to boost efficiency and performance. As for maintenance, regularly check the turbocharger for any signs of damage or wear. Keep an eye on the EGTs, and if they seem unusually high, it might be time to have the turbocharger inspected. Also, follow the manufacturer's recommended service intervals for oil changes and other routine maintenance. When handling the turbocharger, be gentle to avoid any physical damage to the compressor wheel or other components.
