INSTALLING
Installation is done is reverse order, observe the following
Note. There is an unspecified amount of refrigerant oil in the removed compressor so follow the information on replacing the compressor. Removal and Installation .
If necessary, install the compressor driveshaft -A- (in the engine drive wheel) and check the grommet -E- seating.
Note. A clamp on the power take-off flange keeps the grommet -E- from sliding off. Refer to Removal and Installation . The illustration shows the location of the components on a vehicle with a power steering pump. Only vehicles without electro-mechanical power steering have a power steering pump. Refer to Removal and Installation .
If necessary, remove the alignment sleeves -F- from the compressor.
Scheme 59
Thoroughly clean the A/C compressor and bracket surfaces.
Install the alignment sleeves -F- in the bracket or in the A/C compressor.
Before tightening the A/C compressor, check seating of both alignment bushings -A- in bracket or A/C compressor -B-.
Scheme 60
Note. The alignment sleeves -A- have different styles (different lengths), make sure to use the correct style. Ensure bushings -A- are properly seated and contact surfaces are clean. Sockets installed incorrectly and dirty or damaged contact surfaces -C- on the bracket or A/C compressor can lead to alignment irregularities between the A/C compressor and engine. Alignment irregularities over operating time can lead to damage to the drive unit or the A/C compressor.
Tighten the bolts -arrows-.
- Tightening specification: 25 Nm.
Connect electrical connector -1- on A/C Compressor Regulator Valve.
Check the A/C compressor connections and the refrigerant lines for damage or dirt. Refer tot A/C COMPRESSOR REFRIGERANT LINES .
Connect the refrigerant lines to the compressor; bolt tightening specification -A-, for the O-ring dimensions -B- and -C- as well as additional information, refer to A/C COMPRESSOR REFRIGERANT LINES .
Note. Check refrigerant lines and their bracket for sufficient distances to other components. Coat the O-ring seals lightly with refrigerant oil prior to installation. Refer to REFRIGERANT CIRCUIT O-RINGS .
To prevent damaging the compressor the first time is it switched on, turn the compressor drive unit -B- on the compressor by hand 10 rotations in the direction of the arrow -C- before turning the compressor driveshaft -A-.
Note. Refrigerant oil can collect in the compressor compression chamber after removing the compressor or adding new oil (for example, by blowing through the refrigerant circuit). Rotating forces the refrigerant oil out of the compression chamber.
Hold the compressor driveshaft -A- with a wrench and turn the compressor drive unit -B- in the direction of arrow -D-.
- Tightening specification: 60 Nm.
Note. Do not turn the compressor driveshaft -A- when tightening. After installing, check installation position of grommet -E- on drive wheel. After installing the driveshaft -A-, check the boot -E- installation position.
Install the left engine mount. Refer to Removal and Installation .
Install the lower left coolant pipe. Refer to Removal and Installation .
Install the subframe. Refer to Removal and Installation .
Connect the suspension strut to the control arm. Refer to Removal and Installation .
Install the stabilizer. Refer to Removal and Installation .
Connect the CV joint to the steering gear. Refer to Removal and Installation .
Install the power steering hydraulic oil pressure line. Refer to Removal and Installation .
Install the longitudinal braces. Refer to Description and Operation
Note. Replace the seal; the self-locking nuts and the O-ring for the oil dipstick guide tube.
Install the oil dipstick guide tube. Refer to Removal and Installation .
Fill with coolant and bleed the coolant circuit. Refer to General Information .
Evacuate and fill the refrigerant circuit. Refer to A/C Service Station in Description and Operation .
Install the remaining removed components.
Check the Climatronic control module -J255- display and control head DTC memory and erase any displayed malfunctions if necessary. Refer to the Vehicle diagnostic tester in "Guided Fault Finding".
Operate the A/C system after filling the refrigerant circuit. Refer to A/C SYSTEM, OPERATING AFTER FILLING REFRIGERANT CIRCUIT .
Note. Note the information regarding operating the A/C system after filling. Refer to A/C Service Station in Description and Operation .
