Evaporator high-pressure pipe (4-cyl)
|
The evaporator's high-pressure pipe consists of two pipes running from the receiver via a joint by the console behind the right-hand headlamp to the expansion valve.
|
Important
|
|
Be careful not to contaminate the expansion valve.
|
|
|
|
1.
|
Place the car on a lift.
|
|
2.
|
Drain the refrigerant from the A/C system. See
.
|
|
3.
|
Detach the inlet hose with mass air flow sensor, without unplugging the connector, and place it on one side.
|
|
4.
|
Remove the heat shield from the exhaust manifold.
|
|
5.
|
Remove and move away the by-pass pipe including the valve.
|
|
6.
|
Unplug the radiator fan connectors on the fan cowling. Undo the hose clamps holding the hose to the coolant expansion tank.
Cars with automatic transmission:
Disconnect the oil cooler hose from the bottom of the fan cowling.
|
|
7.
|
Remove the fan cowling.
|
|
8.
|
Disconnect and fold away the pressure hose from the turbo.
|
|
9.
|
Detach the front end of the high-pressure pipe from the joint by the console behind the right-hand headlamp and plug the openings.
|
|
10.
|
Detach the pipe from the receiver and plug the openings.
|
|
11.
|
Loosen the pipe from the holders on the subframe and remove it.

|
|
|
12.
|
Loosen and push aside the power-steering oil container.
|
|
13.
|
Detach the rear end of the high-pressure pipe from the expansion valve.
Plug the openings.
|
|
14.
|
Loosen the high-pressure pipe from the holders on the structure.
|
|
15.
|
Carefully lift out the high-pressure pipe.
|
|
1.
|
Position the rear end of the high-pressure pipe.
|
|
2.
|
Remove the plugs. Replace and lubricate the O-rings of the high-pressure pipe.
|
|
3.
|
Connect the high-pressure pipe to the expansion valve.
Tightening torque: 8 Nm (5.9 lbf ft)
|
|
4.
|
Fit the power-steering oil container.
|
|
5.
|
Fasten the pipe with the holders on the structure.
|
|
6.
|
Position the front end of the high-pressure pipe.
|
Note
|
|
Start by inserting the right-hand end of the pipe from left to right down under the compressor. If the pipe is located correctly, it should now fall in place.
|
|
|
7.
|
Remove the plugs. Replace and lubricate the O-rings on both ends of the high-pressure pipe.
|
|
8.
|
Connect the pipe's PAD connector to the receiver.
Tightening torque: 8 Nm (5.9 lbf ft)
|
|
9.
|
Fasten the pipe with the holders on the subframe.

|
|
12.
|
Fit the fan cowling.
|
|
13.
|
Replace the hose clamp and connect the connectors to the radiator fans on the fan cowling.
