General Information
Vane pump is not designed to be serviced. If there are customer complaints, the cause must be determined using a pressure and leak test. If there is a malfunction, replace the vane pump.
• If power steering fluid is low in reservoir, check steering system for leaks.
• If there are leaks in the area of the line connections, the lines/connections must first be inspected for leaks, tightened as necessary and wiped dry.
• Power steering pump is delivered without oil. Therefore, hydraulic oil must be filled before installation and turned by hand. Otherwise, noises when driving or damage to power steering pump may occur.
- Place the vehicle on a hoist.
- Remove the engine cover upward.
• Identify direction of travel before removing ribbed belt. Reversed direction of travel with a used belt can lead to malfunctions. When installing ribbed belt, make sure it is seated correctly on pulleys.
- Remove the ribbed belt.
- Remove the ribbed belt from the power steering pump belt pulley.
- Extract hydraulic oil from reservoir using (V.A.G 1782).
- Clamp off the suction hose - 1 - and return hose - 2 - using the (3094).
• The (3094) must not be secured on the return hose - 2 - in the check valve area. Otherwise, check valve will be damaged.
• The check valve is located in the return hose - 2 - between the hose clamps - arrows -.
- Remove noise insulation.
- Place the (VAS 6208) under the power steering pump.
- Open the hose clamps - arrows - and remove the air guide hose.
Applies to Hot Climate Vehicles
- Disconnect electrical connector - 2 -.
- Remove the bolt - 1 - and move the after-run coolant pump (V51) to the side.
- Carefully cut through the cable ties - 1 - for the wiring harness - 2 - if applicable.
- Remove the clamp - 4 - from the intake hose - 3 -. Remove the suction hose - 3 -.
- Lay several cloths under the power steering pump and pressure line.
- Remove the bolts - 1 - and pull the pressure line - 2 - out of the power steering pump.
- Seal the power steering pump and line connections using clean sealing plugs.
- Remove the two bolts - 1 - for the power steering pump mounting from the front and through the belt pulley.
• The illustration shows the power steering pump without belt pulley.
- Drive the sleeve - 2 - for the bolt - 3 - in the bracket back slightly to install the power steering pump.
- Remove the power steering pump.
Installing
Install in reverse order of removal. Note the following:
Tightening specifications, refer to => [ Vehicles without Dynamic Steering Overview ] Vehicles Without Dynamic Steering Overview
• Replace seals and gaskets.
• Before installing the new power steering pump on the intake side, fill the hydraulic oil and install it by hand until oil drains out on the high pressure side.
• Secure all hose connections with new hose clamps, refer to the Parts Catalog.
- Note the installation position of the intake hose on the power steering pump.
- Note the installation dimension of the clamp. Dimension - a - must be 4 mm.
- Turn the hub by hand until oil runs out of the pressure side.
- Insert the power steering pump in the bracket.
