- the connector and place the power steering reservoir on the engine.
Place the power steering pump up on the engine.
Removing the alternator
Remove:
- the upper screw for the alternator
- the screws common to the alternator and compressor.
Loosen the lower screws for the compressor (so that there is some clearance).
Position the alternator so that it rests against the radiator and on the air conditioning (A/C) compressor.
Removing the fan shroud
Remove the intake manifold for the air cleaner (ACL) housing. Disconnect both the connectors for the engine cooling fan.
Remove:
- the canister purge (CP) valve from the fan shroud for the engine cooling fan
- the four tie straps holding the cable harness by the fan shroud.
Note!
Certain cars have three tie straps and one clip that hold the cable harness by the fan shroud.
Lift out the hose for the expansion tank from the holders on top of the fan shroud. Remove both the screws holding the fan shroud.
Carefully lift up the engine cooling fan (FC).
Loosen the hose clamp for the charge air pipe on the electronic throttle module (ETM). Remove the charge air pipe from the electronic throttle module (ETM).
Remove the 4 x screws for the electronic throttle module (ETM).
Cleaning the electronic throttle module (ETM)
Raise the electronic throttle module (ETM) and place it between the radiator and the intake manifold.
Place paper under the electronic throttle module (ETM).
Clean the throttle and bore as follows.
Note!
Do not use compressed air when cleaning the electronic throttle module (ETM).
Cleaning the ETM
Warning!
DO NOT submerge throttle unit in cleaning solvent. ONLY use cleaning solvent recommended in this TNN.
Important!
Do not scrape or use a rotary wire brush to clean the unit.
Clean the ETM bore using cleaner (P/N 11 61 828) and a soft bristle brush.
Ensure that all the residue is removed from the shaded surfaces shown in the illustration.
Carefully wipe the bore clean on both sides of the throttle plate. Wipe clean the edge of the throttle disc.
Do not use compressed air to dry the throttle module.
Installing the electronic throttle module (ETM)
Install:
- the electronic throttle module (ETM) with a new gasket
- the 4 x screws flush against mating surface.
Cleaning the crankcase ventilation
Remove the banjo bolt from the intake manifold.
Remove the hose (1) from the banjo nipple. Remove the oil filler cap.
Blow the hose clean (1) using compressed air (2) to verify that the system is open. If the hose is blocked clean the hose using 2.0 mm diameter wire.
If air travels through to the oil filler the breather is good, no further verification or repairs are necessary.
Note!
If the hose is blocked, use a welding rod (maximum diameter 2.0 mm, approximately 250 mm long) to unblock the hose.
Clean the banjo nipple using a diameter 2.0 mm drill bit (3).
Install:
- the hose on the banjo nipple
- the banjo bolt with new gaskets
- the oil filler cap.
Raise the car.
Remove the splashguard under the engine
Tighten the banjo bolt. Tighten to 24 Nm.
Tighten the 4 x screws for the electronic throttle module (ETM). Tighten to 10 Nm.
Install the cover under the engine.
Lower the car.
Install the charge air hose to the electronic throttle module (ETM). Tighten the clamp.
Installing the alternator
Install:
- the alternator in the correct position
- the upper screw but do not tighten
- both the screws common to the alternator and the air condition (A/C) compressor. Do not tighten.
Tighten:
- the upper screw. Tighten to 24 Nm
- the lower screws for the air conditioning (A/C) compressor. Tighten to 24 Nm
- the screws common to the alternator and the air conditioning (A/C) compressor. Tighten to 24 Nm.
Installing the fan shroud
Carefully lower the fan shroud and align it with the holders. Pull the cable harness behind the holder (3).
Tighten both the mounting screws. Depress the hose from the expansion tank in the holder on the fan shroud.
Secure the cable harness by the fan shroud using the tie straps (1) and (2). See illustration.
Install the canister purge (CP) valve. Connect the engine cooling fan's connector.
Install:
- the charge air pipe to the turbo and the charge air cooler (CAC)
- the intake manifold to the air cleaner (ACL) housing.
Installing the power steering pump
Install:
- the power steering pump in the correct position
- the 3 x screws through the pulley. Tighten to 24 Nm.
Install the delivery line on the power steering pump. Use new 0-rings on the delivery line.
Tighten to 25 Nm.
Remove the hose clip.
If the vehicle has locking brackets
Install the locking bracket (2). Tighten the screw (1). Tighten to 24 Nm.
Note!
There may be a gap (3) of a few millimeters between the pipe coupling and the power steering pump. Bend the bracket so that the twelve edged mounting on the bracket is on the nut.
Install:
- the auxiliaries belt. Use wrench 999 7109
- the power steering reservoir in its mounting on the expansion tank
- the tie strap for the power steering hose by the suspension turret
