Diesel Engine Turbocharger Installation Tips


All diesel engines reach a point where no matter how much you increase the fuel injection, you can't achieve any additional power. Because of this, the turbocharger was created. Your turbo breathes more air into the combustion chamber, which results in increased power and efficiency, all while cutting down on your emissions.

Because of the speeds at which the turbo spins, even small bits of debris or a change in the proper lubrication can cause it to fail. This can lead to a costly repair for you, particularly if it impacts other systems in your engine. Check out our list of signs you should have your turbocharger serviced for help keeping your turbo running smoothly.

But a failure can happen to any of us. If you find that that's the case for you, it's probably time for a new or remanufactured turbocharger. Proper installation of your turbocharger can help prevent many future issues. Check out our list of helpful tips to ensure you get the best installation possible.

Turbo Installation Tips

Exact guidelines for installing your turbo depend on your engine model and the specific turbocharger you're installing. Refer to the manufacturer's instructions for more information on this.

    • The turbo should be prelubed by adding clean oil to the oil inlet and hand-turning the shaft until oil begins to drain. This helps ensure that all components are properly lubricated prior to startup, which can help prevent future failures. Be sure to use the correct oil as specified by the manufacturer.
    • Keep the turbo clean as you install. Even the smallest amount of dirt or debris can produce catastrophic results, so make sure everything is kept clean as you work.
    • Check the oil passages for any signs of debris. If these particles are allowed to hit the turbine, they can do a lot of damage. A little bit of watchfulness now can save you some headaches in the future.
    • Use new components like gaskets and o-rings. This will help you prevent leaks from reoccurring in the future.
    • Change the oil filter to help prevent build-up that can obstruct oil flow. A new filter can help ensure that the proper amount of oil lubricates your turbo.
    • The oil outlet should be vertical, up to about 20 degrees from vertical.
    • Check that all hoses and connections are properly torqued and connected to avoid leaks.
    • Allow the engine to idle for several for several minutes so that proper oil pressure is achieved.
