INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo]

id0113b5801900

  Warning
  • A hot engine and intake air system can cause severe burns. Turn off the engine and wait until they are cool before removing the intake air system.
  • Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.
  • Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure”. (See BEFORE SERVICE PRECAUTION [L3 Turbo].)

1. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF, L3, L3 Turbo].)

2. Remove the charge air cooler cover.

3. Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [L8, LF, L3, L3 Turbo].)

4. Remove in the order indicated in the table.

5. Install in the reverse order of removal.

6. Complete the “AFTER SERVICE PRECAUTION”. (See AFTER SERVICE PRECAUTION [L3 Turbo].)

7. Add the engine coolant to the cooling system filler neck and the coolant reserve tank to replace that during servicing. (Turbocharger not removed)

8. Refill the engine coolant. (Turbocharger removed)

9. Inspect the engine coolant level. (See ENGINE COOLANT LEVEL INSPECTION [L8, LF, L3, L3 Turbo].)

10. Inspect for engine coolant leakage. (See ENGINE COOLANT LEAKAGE INSPECTION [L8, LF, L3, L3 Turbo].)

11. Perform the following procedure.

  When newly replacing turbocharger

  • Replace the engine oil. (See ENGINE OIL REPLACEMENT [L8, LF, L3, L3 Turbo].)

  When installing a removed turbocharger

  • Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION [L3 Turbo].)

Throttle Body Removal Note

  Warning
  • Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes.
  • When you are sure all the pressure is gone, press down on the cap using the cloth, turn it, and remove it.

  Caution
  • Do not plug the water hose with a sharp-edged object. Otherwise, the hose could be damaged.

Turbocharger not removed

  Note
  • If the turbocharger is not removed at the same time (if only throttle body is removed), remove the throttle body without draining the engine coolant.

1. Wrap a clean cloth around the cooling system cap and release the pressure by loosening the cap slowly.

2. Remove the water hose from the throttle body and plug the water hose quickly.

3. Remove the throttle body.

Turbocharger removed

  Note
  • If the turbocharger is removed at the same time, drain the engine coolant and remove the throttle body.

1. Drain the engine coolant before disconnect the water hose. (See ENGINE COOLANT REPLACEMENT [L8, LF, L3, L3 Turbo].)

2. Remove the throttle body.
