How to Clean a Turbo

How do you know your turbo needs to be cleaned?

The biggest clue a turbo needs to be cleaned is when the vehicle goes into ‘Limp Mode’. Limp mode or limp home mode can be triggered by the restricted movement or sticking of the vanes within the turbo due to excessive carbon build up which in turn leads to ‘overboost’. When overboost occurs the ECU management system kicks in to protect the integrity of the engine by engaging Limp Mode.

Limp mode symptoms:

  • Slow acceleration
  • Engine won't rev beyond a pre-programmed speed
  • Speed restricted to 40mph or similar
  • ECU Management light is on

Using Diesel Turbo Cleaner

Before commencing with the treatment ensure you have taken the recommended safety precautions.

  • Ensure you are in a well ventilated area
  • Make sure the engine is cold
  • Wear the gloves provided
  • Use adequate eye protection
  • Wear a face mask if possible

Once you have established a suitable work environment and you have equipped the relevant safety equipment you may commence with step 1.

Step 1

    1. Remove the exhaust pipe from the turbo charger by undoing the bolts from the flange or the releasing clamp.

    1. Spin the turbine within the turbo to ensure the turbine is free running

    1. Using the exhaust gasket and the blanking card (Turbo Clean Card), determine the position of the holes that need to be made in the card. To easily do this, place the exhaust gasket on the card and line up the centre hole with one of the yellow circles on the card (it does not need to be exact but ensure that you choose the circle that is the closest in size). Ensure you punch a hole into the blanking card through the bolt holes of the exhaust gasket.

Turbo Cleaner Card

    1. Punch a hole through one of the ‘Target Sights’ and insert the cleaning extension tube (Thin tube) through the card to ensure the hole is big enough. If the hole is the correct size remove the cleaning extension tube. If more than one target sight is visible when the exhaust gasket is lined up with the yellow circles choose the upper most completely visible target sight.

    1. Bolt the blanking card to where you removed the exhaust pipe and if possible bolt the exhaust gasket on as well as this does assist in holding the blanking card flatter.

Step 2

    1. Once the blanking card is securely bolted to the turbo, attached one end of the cleaning extension tube to Diesel Turbo Cleaner One and push the other end through the hole that you made in the target sight on the blanking card.

Turbo Cleaner One

    1. Inject about 25% of the Turbo Cleaner One into the turbo and leave for 10mins
    2. After 10mins has elapsed proceed to inject the rest of the Turbo Clean One into the turbo.
    3. You should give the Turbo Cleaner One at least another 45mins before commencing any further, however it is advisable to move the actuator lever using a spanner (if necessary)a few times during this period as this will actually help the chemicals get deeper into the vanes.

Step 3

    1. Once the 45mins have elapsed then place a tray (preferably metal but any tray will do as long as it is emptied fairly quickly as the chemicals will eat through plastic if left overnight) underneath the exhaust section of the turbo and remove the blanking card.
    2. The dissolved dirt and carbon will flow out of the exhaust section of the turbo.
    3. Once the dissolved solution has stopped flowing from the exhaust side of the turbo, you can bolt the blanking card back onto the turbo. If the blanking card is badly damaged you can proceed without bolting it back on.
    4. Attach the cleaning extension tube to Diesel Turbo Cleaner Two and proceed to spray the solution into the exhaust end of the turbo, taking care to remove all dirt, carbon and residue of Turbo Cleaner One within the turbo.

Step 4

    1. The inside of the turbo should now be free of carbon and dirt.

    1. Now you have completely cleaned the turbo, reattach the exhaust gasket and the exhaust pipe to the turbo.

Assemble Turbo and Exhaust

    1. To prevent carbon build up happening again, pour Diesel Treatment into the fuel filter (if you are unsure where your fuel filter is situated then consult your vehicle workshop manual). This will ensure the injectors and combustion chamber is completely clean thus restoring the vehicle to optimal performance.
