GARRETT TURBOCHARGERS
INSTALLATION INSTRUCTIONS
Before installing a new or repaired tube it is important to find out why the previous tube broke. Consult your Garrett distributor if you have any queries.
WARNING:
- Not following these instructions can cause the turbo to break and void the warranty.
- Changing the turbo valve calibration can damage the turbo and the engine, and void the warranty.
- It is essential to use the right seals, the wrong ones can block the oil holes.
| 1. |
Seals covering a part of the hole. They reduce oil feed to the turbo and the excess material can break off and block the oil flow. |
| 2. |
The seal must leave the hole totally clear. Liquid seals or sealants are not recommended, especially for the oil inlet and outlet. Excess sealant can come away and block oil flow into the tube. |
- Follow the engine or vehicle manufacturer's instructions for choosing the right type and amount of oil for the engine, as well as for the tightening torques and installation instructions.
- Prevent dirt or debris from entering during installation.
- Before installing the turbo, check that the reference matches the application. Fitting the wrong turbo can damage the turbo and/or the engine, and can also void the warranty.

TURBO INSTALLATION
- All the air tubes and hoses must be clean and not have any dents or cracks.
- The air filter and casing must be clean and free of coking.
- Clean the engine vent and check it runs smoothly.
- Remove the old seals and clean the surfaces. These should not be damaged.
- REMOVE THE PLASTIC OR FOAM RUBBER PROTECTION FROM THE NEW OR REPAIRED TURBO BEFORE FITTING IT.
- Fill the turbo oil hole with clean oil and give the rotor a few spins with your hand (it should spin freely). NOTE: a little slack at the top and bottom of the rotor is normal.
- Fit the turbo on the manifold using a new seal and then connect the exhaust pipe. Tighten all the screws and nuts.
- The oil and drain lines must be totally clear and free of any dents. Oil flow must not be restricted. Check that no hose has any internal obstructions. Check that the oil inlet is not too close to any heat source. 3. Even if the oil level is correct, if the drain line is damaged, oil can be lost through the turbo.
- Fit the oil drain line. Put oil back into the turbo oil hole and connect the oil inlet.
- Fit the air lines and tighten.
- Use new air, oil and fuel filters. Change the engine oil.
- If possible wait 10-15 seconds before starting the engine. Keep the engine idling 3 to 4 minutes before accelerating. Check if there are any oil or air leaks.
- Stop the engine and check the oil level. Note: the oil level must not be above the turbo oil return hole.
| 4. |
A very high oil level blocks the turbo oil outlet, causing oil loss in the turbo. |
| 5. |
The oil must be at the correct level.
Check the compression. A very high pressure may be caused by gases flowing from the cylinders to the crankcase.
|
| 6. |
Excessive compression may impede the return of oil from the turbo to the crankcase, causing oil loss in the turbo. |
