Installation Notes
A quick note on the install: This is a straightforward job if you're methodical. The key is dealing with the heat and ensuring a perfect seal.
Let it Cool Completely: This is the most important step. Never work on the exhaust system when the engine is hot. Allow it to cool down entirely to avoid burns.
Access the Component: You'll likely need to remove other components or heat shields to get clear access to the turbo elbow. Have a set of tools handy.
Remove the Old Elbow: Unbolt the connecting elbow from the turbocharger outlet and the downstream exhaust pipe. You might need to gently persuade it if it's stuck, but avoid using excessive force.
Clean the Mating Surfaces: This is critical for preventing leaks. Thoroughly clean the flanges on the turbo and the exhaust pipe. All old gasket material must be removed. A wire brush works well for this.
Install with New Gaskets: Always use new gaskets. Position the new VG1246110142B elbow and hand-tighten the bolts to align it.
Tighten to Specification: Follow a star pattern to tighten the bolts evenly. If you have a torque wrench, refer to the service manual for the correct specification. If not, tighten firmly and evenly to ensure a uniform seal.
Re-assemble & Check for Leaks: Reinstall any components you removed. Start the engine and carefully listen and feel around the new elbow for any exhaust leaks. A small piece of paper will flutter if held near a leak.
