Preparation
Before starting the installation, ensure that you have all the necessary tools and materials. Additionally, make sure the vehicle is parked on a level surface, and the engine is cool.
Step 1: Disconnect the Battery
To prevent any electrical issues, disconnect the negative terminal of the battery. This will ensure safety during the installation process.
Step 2: Remove the Existing Turbocharger
Begin by removing the intake and exhaust pipes connected to the existing turbocharger. Use the socket set to remove the bolts securing the turbo to the manifold.
Carefully lift the old turbocharger out of its position, taking care not to damage any surrounding components. Make sure to catch any oil that may spill during this process.
