GENERAL NOTES
The instructions here are organized so that you work on only one component group at a time.
This will help avoid confusion from similar±looking parts of different subassemblies being on your work-
bench at the same time.
The component groups are inspected and repaired from the converter housing side.
As much as possible, complete the inspection, repair and assembly before proceeding to the next compo-
nent group. If a component group cannot be assembled because parts are being ordered, be sure to keep
all parts of that group in a separate container while proceeding with disassembly, inspection, repair and
assembly of other component groups.
Recommended fluid for the automatic transaxle: ATF D±@@@@@: [g 2] or DEXRON®@@@@@: [g
3](DEXRON®@@@@@: [g 2])
1. GENERAL CLEANING NOTES:
(a) All disassembled parts should be washed clean and any fluid passages and holes blown through with
compressed air.
(b) When using compressed air to dry parts, always aim away from yourself to prevent accidentally spray-
ing automatic transaxle fluid or kerosene in your face.
(c) The recommended automatic transaxle fluid or kerosene should be used for cleaning.
2. PARTS ARRANGEMENT:
(a) After cleaning, the parts should be arranged in the correct order to allow efficient inspection, repairs,
and reassembly.
(b) When disassembling a valve body, be sure to keep each valve together with the corresponding spring.
(c) New brakes and clutches that are to be used for replacement must be soaked in transaxle fluid for at
least fifteen minutes before assembly.
3. GENERAL ASSEMBLY:
(a) All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with
transmission fluid prior to reassembly.
(b) All gaskets and rubber O±rings should be replaced.
(c) Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed in the
groove correctly.
(d) If a worn bushing is to be replaced, the subassembly containing that bushing must be replaced.
(e) Check thrust bearings and races for wear or damage. Replace if necessary.
(f) Use petroleum jelly to keep parts in place.

REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Loosen the radiator drain plug (on the right side of the ra-
diator lower tank) and engine drain plug (on the left rear
of the cylinder block), and drain the coolant.
(c) Close the drain plugs.
Torque: 25 N´m (250 kgf´cm, 18 ft´lbf) for engine
2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.
Use of improper coolants may damage engine cool-
ing system.
Use ºToyota Long Life Coolantº or equivalent and
mix it with plan water according to the manufactur-
er's directions.
Using of coolant which includes more than 50 %
(freezing protection down to ±35°C (±31°F) or 60 %
(freezing protection down to ±50°C (±58°F)) of eth-
ylene±glycol is recommended but not more than 70
%.
NOTICE:
Do not use an alcohol type coolant or plain water
alone.
The coolant should be mixed with plain water (prefer-
ably demineralized water or distilled water).
Capacity:
w/ Oil cooler6.9 litters (7.3 US qts, 6.1 lmp. qts)
w/o Oil cooler6.2 litters (6.5 US qts, 5.4 lmp. qts)
(b) Install the radiator cap.
(c) Start the engine, and bleed the cooling system.
(d) Refill the radiator reservoir with coolant until it reaches the
ºFULLº line.

(a) Remove the bolt holding the dipstick guide to the LH cylin-
der head.
(b) Pull out the dipstick guide together with the dipstick from
the No.1 oil pan.
(c) Remove the O±ring from the dipstick guide.
30. REMOVE CYLINDER HEAD COVERS
Remove the 8 bolts, cylinder head cover and gasket. Remove
the 2 cylinder head covers.
31. REMOVE CAMSHAFTS OF RH CYLINDER HEAD
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be held level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Remove the intake camshaft.
(1) Align the timing marks (2 dot marks) of the camshaft
drive and driven gears by turning the camshaft with
a wrench.
(2) Secure the exhaust camshaft sub±gear to the main
gear with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 ± 20 mm (0.63 ± 0.79 in.)
