Step-by-Step Removal Guide for Your Twin Turbos

Alright, let's get down to business and get those turbos out! This section provides a detailed step-by-step guide on how to perform the Nissan Navara twin turbo removal. Follow these steps carefully, and you'll be on your way to a successful removal. Remember to take your time and double-check everything as you go. Alright, let's do this!

Preparation: First things first, disconnect the negative battery terminal. This is a crucial safety step to prevent any electrical mishaps. Next, safely raise and support your Navara using a jack and jack stands. Make sure the vehicle is stable before you start working underneath. Get yourself prepared and ready to get your hands dirty!
Drain the Coolant: Locate the drain plug for the engine coolant. Place your drain pan underneath and carefully drain the coolant. Be sure to dispose of the coolant properly. Coolant is toxic, so be careful handling it.
Drain the Oil: Locate the oil drain plug and drain the engine oil. Again, place your drain pan underneath. Allow the oil to drain completely. It is important to drain the oil and coolant before removing the turbos.
Remove Air Intake Components: Start by removing the air intake system. This typically involves removing the air filter box, intake hoses, and any related components that are in the way. Label everything clearly, and keep track of all the bolts and screws.
Disconnect Turbocharger Hoses: Carefully disconnect all hoses connected to the turbochargers. This includes the oil feed and return lines, coolant lines, and any vacuum hoses. Use pliers or screwdrivers to loosen clamps, and label everything. Keep track of which hose goes where.
Disconnect Exhaust Components: Remove the exhaust downpipes or headers connected to the turbochargers. This might involve removing heat shields and other components. Be careful with the exhaust components, as they can be hot even after the engine has cooled down. Use penetrating oil if the bolts are stubborn.
Loosen and Remove the Turbocharger Mounting Bolts: Locate and loosen the bolts that secure the turbochargers to the engine. These bolts can be in hard-to-reach places. Use your socket set, extensions, and a breaker bar if necessary. Once the bolts are loose, remove them completely.
Carefully Remove the Turbochargers: With all the connections and bolts removed, you should be able to carefully remove the turbochargers. They might be a bit stuck, so gently wiggle them until they come loose. Be prepared for some oil spillage. Have your shop towels ready.
Clean the Mounting Surfaces: Before installing new turbochargers, or any components, clean the mounting surfaces on the engine block and exhaust manifold. Use a scraper and some brake cleaner to remove any old gasket material and debris.
Inspect and Prepare for Reassembly: Inspect the removed turbochargers for any damage. Check for play in the turbine shafts. If you're replacing the turbos, now is the time to install the new ones. If you're upgrading, prepare the new turbos for installation.

Troubleshooting Common Issues

During the Nissan Navara twin turbo removal process, you might encounter some common issues. Here are some tips to help you overcome these challenges:

Stubborn Bolts: If you encounter bolts that are difficult to remove, try applying penetrating oil and letting it soak for a while. Use a breaker bar or impact wrench to help loosen them. Remember to be patient and avoid stripping the bolt heads.
Tight Spaces: The engine bay of the Navara can be quite cramped. Use extensions, universal joints, and flexible tools to reach those hard-to-access bolts. Take your time and plan your moves carefully.
Rust and Corrosion: If you live in an area with a lot of rust, you might encounter corrosion on the bolts and components. Use penetrating oil generously and consider using a wire brush to clean up the bolts before attempting to remove them.
Stripped Threads: If you strip a thread, don't panic. You can try using a thread repair kit or helicoil to fix the threads. Alternatively, you can tap the hole to a larger size and use a larger bolt. Just be extra careful.
Difficulty Removing Turbochargers: Sometimes the turbochargers can be stuck to the exhaust manifold or engine block. Gently wiggle them back and forth while applying some force. Avoid using excessive force to avoid damaging the turbochargers or other components. If necessary, use a rubber mallet to gently tap on the turbocharger housing.
Finding the Right Parts: Make sure you have the right parts for your specific model and year of your Navara. Double-check part numbers and consult a service manual to ensure compatibility. If you're unsure, it is always best to consult with a professional mechanic.

Tips for a Smooth Removal
