Carefully disconnect any sensors or electrical connectors attached to these components. Often, you'll find clips or screws holding everything together. Remember to keep track of where each part goes. Taking photos as you go can be a lifesaver when it comes time to reassemble everything!

Next, focus on the exhaust system. This is where things can get a bit tricky due to the heat. First, you need to disconnect the exhaust downpipes from the turbochargers. These pipes are often held in place with bolts. Be careful, as these bolts can be rusted and difficult to remove. Use penetrating oil and give them time to soak if necessary. Once the downpipes are detached, you can work on removing the rest of the exhaust system. This might involve disconnecting the exhaust from the catalytic converters or the rest of the exhaust system. Again, it is important to remember what connects to where. Consider marking them with tape or using a marker to note their locations. Carefully lower the exhaust system, keeping in mind that it can be heavy. Having a helper is always a good idea.

With the air intake and exhaust components out of the way, you should now have a clearer view of the turbochargers. You might encounter additional brackets, heat shields, or other components that need to be removed to fully expose the turbos. Taking your time, documenting each step, and referring to your service manual will ensure you remove these components safely and efficiently. Remember, patience and organization are key in this stage of the Nissan Navara twin turbo removal.

Now that we have a clear view of the turbos after dismantling the surrounding components, let's move forward in our Nissan Navara twin turbo removal guide. This stage is all about carefully disconnecting the various lines and fittings connected to the turbochargers. First, you'll need to disconnect the oil feed and return lines. These lines are responsible for lubricating the turbochargers. Locate these lines (they'll typically have banjo bolts or fittings). Place a container under the fittings to catch any residual oil, then carefully loosen and disconnect the lines. Be prepared for a bit of oil leakage.

Next, disconnect the coolant lines. Like the oil lines, these are essential for cooling the turbochargers. Carefully detach the coolant lines from the turbos. Again, you will likely need to catch any coolant that leaks out. With the oil and coolant lines detached, it's time to work on the manifold connections. Locate the bolts securing the turbochargers to the exhaust manifold. These bolts are often subjected to extreme heat and can be difficult to remove. Apply penetrating oil and give them time to soak before attempting to loosen them. It may be necessary to use a breaker bar to break them free.

Once the bolts are loosened, carefully remove the turbochargers from the manifold. They might be a bit stuck due to carbon buildup or corrosion. Gently wiggle the turbochargers until they break free. With the turbochargers detached, inspect the exhaust manifold for any damage or wear. Finally, repeat the same process for the second turbocharger. By carefully disconnecting the lines, loosening the bolts, and taking your time, you'll successfully remove the turbochargers from your Nissan Navara. Keep all removed parts organized for reassembly or future use. Safety and a methodical approach are the keys to success in this step.
