A/C High Pressure Line

Removal

1. Recover the refrigerant from the A/C system (

See page 31-66

).

2. Turn off all the electrical equipment and ignition switch.
3. Disconnect the negative battery cable.
4. Remove the front bumper assembly (

See page 48-11

).

5. Remove the A/C high pressure line I (compressor to evaporator).

a. Remove the fixing bolt (arrow) between A/C high/low

pressure line and expansion valve, and disengage the
A/C high pressure line I.



(Tightening torque: 7 ± 1 N·m)

b. Remove the coupling nut (arrow) between A/C high/

low pressure line fixing bracket and body, and
disengage the A/C high pressure line I.



(Tightening torque: 7 ± 1 N·m)

c. Disconnect the A/C pressure sensor wire harness

connector (arrow).

CAUTION

 Special service equipment for R134a refrigerant must be used to recover/charge refrigerant.
 Always keep the work area in good ventilation.
 The disconnected A/C line and connecting part should be sealed to prevent foreign matter from entering.

CAUTION

 Tighten fixing bolts and fixing nuts to specified torque.
 It is necessary to replace the refrigerant line O-ring when installing the refrigerant line. Failure to do so

may result in refrigerant leaks.

 Lubricate the new rubber O-ring with clean refrigerant oil and install it to the refrigerant line joint.
 Only use the specified O-ring, as it is made of special materials for R134a system.
 Only use recommended refrigerant oil which is applicable to the A/C compressor assembly on vehicle.
 Perform recharging for the A/C system and check refrigerant for leakage.

Compressor Assembly

Removal

1. Recover the refrigerant from the A/C system (

See page 31-66

).

2. Turn off all the electrical equipment and ignition switch.
3. Disconnect the negative battery cable.
4. Remove the engine lower right protector assembly.
5. Remove the power steering pump assembly (

See page 29-17

).

6. Remove the compressor assembly.

a. Turn the tensioner with a wrench in the direction of

arrow as shown in the illustration, and then remove
the accessory drive belt (1).

b. Remove the idler pulley fixing bolt (arrow) and then

remove the idler pulley (1).

WARNING

 Be sure to follow the safety precautions before performing the procedure. Failure to do so may result in

serious personal injury or even death.

CAUTION

 Special service equipment for R134a refrigerant must be used to recover/charge refrigerant.
 Always keep the work area in good ventilation.
 The disconnected A/C line and connecting part should be sealed to prevent foreign matter from entering.
 If the A/C compressor assembly has an internal malfunction, it is necessary to replace the A/C fluid line.

Failure to do so may result in a serious damage to A/C compressor assembly after replacing.

 When replacing compressor assembly, it is necessary to measure the refrigerant oil amount removed

from the new A/C compressor assembly.
