Select Your Vehicle

As a truck fanatic, you might be thinking of replacing your turbocharger to ramp up performance and increase power. You could also want to prepare it for competitive use, improve drivability, and improve towing. Whatever your goals, the following tips by the experts at Taylor Diesel Group will aid you in the process.

1. Identify the root of the problem

Most people are quick to replace their turbochargers when they stop working without determining the cause of the failure. It is a grave mistake that can be a costly one in the future if the root issue isn’t diagnosed and repaired.

Turbochargers may fail because of continued use, but there are also other factors to consider—intake and exhaust restrictions, improper maintenance, and intake and exhaust leaks, for example.

Contamination of engine oil is another major cause of turbo failure, and the culprit is the high RPMs under boosted conditions. The maximum RPMs range is from 80,000 to 200,000, hence the need for proper oil change intervals.

2. Oil pipes and engine oil

Before installing a new turbocharger, change the oil and filtration systems. Start with the oil pipe from the turbocharger, ensuring that the new one is free of blockages and kinks.

You should also replace the oil filter and engine oil, in that order. Fresh, clean oil prevents problems associated with impurities in the old engine oil.

Don’t forget to repair or remove all the crankcase hoses and filters, too.

3. Clean your engine

Cleanliness is a vital part of the process as it removes particulates from the engine, preventing further damage to the turbo. To purify the engine, immobilize it, then turn it over and pump out half a pint of oil via the oil feed pipe.

4. Remove the old turbocharger

This process is as simple as separating the old turbocharger from the exhaust manifold. Once you unscrew all bolts and nuts holding them together, lift the turbocharger out below the engine compartment or through the top.

5. Install the new turbocharger

Join the new turbocharger to the exhaust manifold. Be sure to tighten the nuts and bolts to the right torque values based on the manufacturer’s guide.

Before you set up your new turbocharger, check that it is the right fit for your vehicle. Compare it with the old turbocharger, and if all the linking parts are in the same areas, go ahead with the replacement.

6. Reconnect everything

Detach the blanking plug and ensure that the turbocharger bearing housing has no oil. Refit the oil pipe and connect it to the turbocharger. While doing so, take care not to over-tighten the connections.

7. Final check

Double-check your work before calling it a day.

  • Start the vehicle and check for any oil leaks from the turbocharger.
  • Ensure that the exhaust manifold and down pipe doesn’t emit any exhaust fumes.
  • Use a boost gauge to check if the boost pressure is within limits specified by the manufacturer.

That’s it!
