Compressor, Removing From Bracket
Compressor, Removing from Bracket
4- or 6-Cylinder with Compressor Belt Drive
• The compressor can be removed and installed at the bracket without opening the refrigerant lines.
• Do not discharge the refrigerant circuit, do not remove refrigerant hoses and lines from compressor.
• After detaching, use wire to attach compressor to longitudinal member. Never leave hanging from refrigerant pipes.
• Before removing, mark direction of operation of ribbed belt with chalk or felt-tipped pen. Running a used belt in the opposite direction could destroy it.
• Different compressors are installed, depending on engine and country version (installed on right or left of engine, 6-cyl. gasoline engine, country with cold or hot climate).
Compressor on Right Side of Engine
• Do not disconnect the refrigerant lines and clamp - D -.
- Remove noise insulation.
- Bring the lock carrier into service position. Refer to =>
Radiator Support Radiator Support
- Release tension on ribbed belt and remove it.
- Remove bolts - A - (25 Nm).
• Install one washer each - B - at bolts - A -.
• Before fastening compressor, check both bushings - C - in bracket or compressor for correct seating.
• After securing the compressor, check the routing of the refrigerant lines - A -. They must be in the provided brackets - B -.
• After securing the compressor, check the refrigerant lines and their bracket for sufficient distances to other components.
Compressor on Left Side of Engine
• The compressor is installed on the left side of the engine in a 1.6 l gasoline engine and in 6-cylinder engines, for example
• Do not unfasten refrigerant pipes and corresponding clamps.
• The figure shows the compressor for a 4-cyl. gasoline turbo engine. The layout only differs slightly from this figure in other engine versions (e.g. other refrigerant lines).
- Remove the noise insulation.
- Move the lock carrier to the service position (only if the ribbed belt and the compressor cannot be removed without the service position, e.g. not necessary in the 6-cylinder engine, e.g. in the 2.0 l 4-cylinder engine). Radiator Support Radiator Support
- Remove the oil filter. Protect the sealing surfaces from damage (only necessary in certain 6-cylinder gasoline engines).
- Release the tension and detach the ribbed belt.
- Remove bolts - A - (25 Nm).
• Install one washer each - B - at bolts - A -.
• Before fastening compressor, check both bushings - C - in bracket or compressor for correct seating.
• After securing the compressor, check the routing of the refrigerant lines - A -. They must be in the provided brackets - B -.
• After securing the compressor, check the refrigerant lines and corresponding brackets for adequate clearance with respect to other components, ensuring sufficient distance between the belt, bracket, and belt pulley in vehicles with a 6-cylinder engine.
8-Cylinder with Compressor Driveshaft
• Compressor is driven via a toothed gear and a driveshaft - B -.
• Compressor bracket, removing from engine and installing. Refer to => Engine Mechanical Engine
• To remove the compressor on vehicles with an 8-cyl. engine, the refrigerant circuit must be drained and then both refrigerant lines must be removed from the compressor.
