30. Check foreign materials in oil pan to help determine causes of malfunction. 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 c ause valves, servo, and clutches
to stick and can inhibit pump pressure.
 If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT-13, "
A/T Fluid Cooler Cleaning".
31. Remove magnets from oil pan.
32. Disconnect A/T fluid temperature sensor 2 connector (1). CAUTION:
Be careful not to damage connector.
33. Straighten terminal clips ( ) to free terminal cord assembly and A/T fluid temperature sensor 2 harness.
34. Disconnect revolution sensor connector. CAUTION:

REFRIGERANT LINES
 O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2 (high-

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

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

BRAKE TUBE AND HOSE
BRAKE TUBE AND HOSE
Hydraulic CircuitINFOID:0000000001327613
CAUTION:
 All brake hoses and tubes must be free from excessive bending, twisting and pulling.
 Make sure there is no interference with other part s when turning steering both clockwise and coun-
terclockwise.
 The brake tubes and hoses is an important safety pa rt. If a brake fluid leak is detected, always disas-
semble the parts. Replace applicable part with a new one, if necessary.
 Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of bo dy, immediately wipe it off and them wash it away with water
immediately.
 Do not bend or twist brake hose sharply, or strongly pull it.
 When removing components, cover br ake line connections so that no dirt, no dust, or other foreign
matter gets in.
 Refill with new brake fluid “ DOT 3 ”.
 Do not reuse drained brake fluid.
