Replacement

7.4 N·m
(0.8 kgf·m, 5.5 lbf·ft)

A
9.8 N·m (1.0 kgf·m, 7.2 lbf·ft)

1. Remove the bolt and the holder (A). Disconnect the

field coil connector (B), then remove the thermal
protector (C).

2. Replace the thermal protector (A) with a new one,

and apply silicone sealant (B) to the bottom of the
thermal protector.

3. Install the thermal protector in the reverse order of

removal.

NOTE: If the A/C compressor relief valve released
refrigerant to the atmosphere, determine and correct
the cause of the excessive system pressure, then
replace the relief valve.

1. Recover the refrigerant with a recovery/recycling/

charging station (see page 21-90).

2. Remove the relief valve (A), and the O-ring (B). Plug

the opening to keep foreign matter from entering
the system and the A/C compressor oil from
running out.

3. Clean the mating surfaces.

4. Replace the O-ring with a new one at the relief

valve, and apply a thin coat of refrigerant oil before
installing it.

5. Remove the plug, and install and tighten the relief

valve.

6. Charge the system (see page 21-92).

Receiver/Dryer Desiccant
Replacement

6 x 1.0 mm
9.8 N·m
(1.0 kgf·m, 7.2 lbf·ft)

8. Remove the A/C condenser (A) by lifting it up. Be

careful not to damage the radiator and A/C
condenser fins when removing the A/C condenser.

9. Install the A/C condenser in the reverse order of

removal, and note these items:

• If you’re installing a new A/C condenser, add

refrigerant oil (SP-10) (see page 21-7).

• Replace the O-rings with new ones at each fitting,

and apply a thin coat of refrigerant oil before
installing them. Be sure to use the correct O-rings
for HFC-134a (R-134a) to avoid leakage.

• Immediately after using the oil, reinstall the cap

on the container, and seal it to avoid moisture
absorption.

• Do not spill the refrigerant oil on the vehicle; it

may damage the paint; if the refrigerant oil
contacts the paint, wash it off immediately.

• Charge the system (see page 21-92).
• Adjust the hood latch (see page 20-152).

NOTE: Install the receiver/dryer as quickly as possible
to prevent the system from absorbing moisture from
the air.

1. Remove the A/C condenser (see page 21-88).

2. Remove the bolts from the A/C condenser, then

remove the receiver/dryer (A), the bracket (B), and
the O-rings (C).

3. Install the receiver/dryer in the reverse order of

removal. Replace the O-rings with new ones, and
apply a thin coat of refrigerant oil (SP-10) before
installing them. Be sure to use the correct O-rings
for HFC-134a (R-134a) to avoid leakage.
