6. Check foreign materials in oil pan to help determine causes ofmalfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.
 If frictional material is de tected, perform A/T fluid cooler
cleaning. Refer to AT-13, "
A/T Fluid Cooler Cleaning".
7. Disconnect A/T fluid temperature sensor 2 connector (1). CAUTION:
Be careful not to damage connector.
8. Straighten terminal clip ( ) to free A/T fluid temperature sensor 2 harness.
9. Remove A/T fluid temperature sensor 2 with bracket from con- trol valve with TCM.
10. Remove bracket from A/T fluid temperature sensor 2.
Installation
CAUTION:
After completing installation, check A/T fluid leakage and A/F fluid level. Refer to AT- 11 , "
Checking A/T
Fluid".

REFRIGERANT LINES
 O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2 (high-
pressure pipe 3).
 Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sensor
can be located in the same position.
 When recharging refrigerant, check for leaks.
Removal and Installation of Expansion ValveINFOID:0000000001328230
REMOVAL
1. Remove evaporator. Refer to ATC-137, "Removal and Installation of Evaporator".
2. Remove mounting bolts, and then remove expansion valve. CAUTION:
Cap or wrap the joint of evaporator with suitable material
such as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
 Replace O-rings of evaporator with new ones, and then apply compressor oil to it when installing it.
 O-rings are different from low-pressure pipe 1 (h igh-pressure pipe 2) and low-pressure pipe 2 (high-
pressure pipe 3).
 When recharging refrigerant, check for leaks.
Checking of Refrigerant LeaksINFOID:0000000001328231
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage ma y indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electrical leak detector or fluorescent dye leak
detector (SST: J-42220).
If dye is observed, c onfirm the leak with an electrical leak detector. It is possible a prior leak was repaired and
not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electric al leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electrical leak detector probe slower and closer to the suspected leak area will improve the
chances of finding a leak.
Checking System for Leaks Using the Fluore scent Leak DetectorINFOID:0000000001328232
1. Check A/C system for leaks using the UV lamp and safety goggles (SST: J-42220) in a low sunlight area
(area without windows preferable). Illuminate all co mponents, fittings and lines. The dye will appear as a
bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain open-
ing indicates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (SST: J-43872) to prevent future
misdiagnosis. Low-pressure pipe 1 bracket mounting bolt

4. Remove reservoir tank and reservoir tank bracket.
5. Disconnect A/T fluid cooler hoses from radiator.
 Install blind plug to avoid leakage of A/T fluid.
6. Removal radiator hoses (upper and lower) and reservoir tank hose. CAUTION:
Be careful not to allow engine coolant to contact drive belts.
7. Remove radiator cooling fan assembly. Refer to CO-20, "

8. Rotate two radiator upper mount brackets 90 degrees in the direction shown in the figure, and remove them.
9. Lift up and remove radiator. CAUTION:
Do not damage or scratch A/C condenser and radiator core
when removing.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION
 Check for leaks of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-10, "
Inspection".
 Start and warm up the engine. Visually make sure t hat there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapINFOID:0000000001325849
 Check valve seat of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
- Check if valve seat has no soil and damage.

Checking Radiator CapINFOID:0000000001325873
 Check valve seat of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
- Check if valve seat has no soil and damage.
 Pull negative-pressure valve to open it, and make sure that it close
completely when released.
- Make sure that there is no dirt or damage on the valve seat of radi-
ator cap negative-pressure valve.
- Make sure that there are no unusualness in the opening and clos- ing conditions of negative-pressure valve.
 Check radiator cap relief pressure.
- When connecting radiator cap to the radiator cap tester adapter (commercial service tool) (B) and t he radiator cap tester (commer-
cial service tool) (A), apply engine c oolant to the cap seal surface.
 Replace radiator cap if there is an unusualness.
