Remove Turbocharger Bolts
Locate and remove the bolts securing the turbocharger to the engine. Use a torque wrench to ensure they are loosened correctly.
Take Out the Turbocharger
Once the bolts are removed, carefully take out the old turbocharger from its mounting position. Be cautious of any remaining oil or coolant.
Installing the Upgraded Turbocharger
With the old turbocharger removed, it’s time to install the upgraded turbocharger.
Prepare the New Turbocharger
Before installation, ensure the new turbocharger is clean and free of debris. Compare it with the old unit to confirm compatibility.
Install New Gaskets
Install new gaskets on the turbocharger mounting surface. This will help create a proper seal and prevent leaks.
Mount the Turbocharger
Carefully place the new turbocharger onto the engine and align it with the mounting holes. Secure it with the bolts you previously removed.
Reconnect Exhaust and Intake
Reconnect the exhaust and intake pipes to the new turbocharger, ensuring all clamps and bolts are tightened securely.
