2429316 - 5040B30 expansion valve (tube orifice) - r+r

Follow the safety instructions (See 5040 - Precautions)

) Place the vehicle on a lift. Drain the coolant ( - 0010T84 coolant for air conditioning system dehydrate and recharge ). 1. Loosen the bands (1a) and remove the hose (1b) from the air filter to the flow meter.

1. Working in the area of the compressor, release the pipe from the expansion valve to the evaporator (1a) from the retainers (1b).

1. Undo the bolt (1a) and disconnect the connector (1b) for the pipe from the expansion valve to the compressor.

Seal the disconnected connectors, using suitable plugs, to prevent humidity and impurities from entering the system.

2. Undo the bolt (2a) and disconnect the connector (2b) for the pipe from the expansion valve to the condenser.

1. Undo the bolts fixing the expansion valve. 2. Remove the expansion valve.3. Recover the gaskets.

Do not reuse the seals when refitting.

Refitting ( Removing

) Check that the expansion valve is not damaged.Position the new gaskets on the expansion valve, then secure it using the bolts.

Replace the O-rings for the connectors. Only use green coloured seals, resistant to R134A coolant fluid. Lubricate the thread of the connectors using anti-freeze.

1. Connect the connector (1a) for the pipe from the expansion valve to the compressor, expansion valve side and secure it tightening the bolt (1b) to the recommended torque.

Working in the area of the compressor, attach the pipe from the expansion valve to the evaporator to the retainers.Place the hose from the air filter to the flow meter in position and fasten it using the bands. Repressurize using coolant fluid ( - 0010T84 coolant for air conditioning system dehydrate and recharge ). Remove the vehicle from the lift.
