coolant reservoir TOYOTA SUPRA 1995 Service Repair Manual

COOLANT CHECK
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR
RESERVOIR
The engine coolant level should be between the ºLOWº and
ºFULLº lines.
If low, check for leaks and add engine coolant up to the
ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not remove
the radiator cap while the engine and radiator are still hot, as
fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale
around the radiator cap or radiator filler hole, and the coolant
should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap. EG±330

COOLANT REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not remove
the radiator cap while the engine and radiator are still hot, as
fluid and steam can be blown out under pressure.
(b) Loosen the 2 drain plugs (for the engine and radiator), and
drain the coolant.
(c) Close the drain plugs.

2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.
wUse a good brand of ethylene±glycol base coolant and
mix it according to the manufacturer's directions.
wUsing coolant which includes more than 50 %
ethylene±glycol (but not more than 70 %) is
recommended.
NOTICE:
wDo not use an alcohol type coolant.
wThe coolant should be mixed with demineralized water or
distilled water.

OIL COOLER REMOVAL
1. DISCONNECT PS RESERVOIR TANK WITHOUT
DISCONNECTING HOSES
(a) Disconnect the 2 clamps of the engine wire protector from the
bracket.
(b) Remove the 3 bolts and disconnect the reservoir tank.
2. DRAIN ENGINE COOLANT
3. REMOVE OIL FILTER
4. DISCONNECT WATER BYPASS HOSES FROM OIL
COOLER
5. REMOVE OIL COOLER
(a) Remove the relief valve, plate washer and oil cooler.
(b) Remove the 2 O±rings from the oil cooler.
OIL COOLER INSPECTION
1. INSPECT RELIEF VALVE
Push the valve with a wooden stick to check if it is stuck.
If stuck, replace the relief valve.
2. INSPECT OIL COOLER
Check the oil cooler for damage or clogging.
If necessary, replace the oil cooler.
OIL COOLER INSTALLATION
1. INSTALL OIL COOLER
(a) Install 2 new O±rings to the oil cooler.
(b) Apply a light coat of engine oil on the threads and under the
head of the relief valve.
(c) Temporarily install the oil cooler with the plate washer and
relief valve.
(d) Tighten the relief valve.

18. BRAKE PEDAL
(a) Check that pedal for smooth operation.
(b) Check that the pedal has the proper reserve
distance and freeplay.
(c) Check the brake booster function.
19. BRAKES
At a safe place, check that the brakes do not
pull to one side when applied.
20. PARKING BRAKE
(a) Check that the pedal has the proper travel.
(b) On a safe incline, check that the vehicle is
held securely with only the parking brake
applied.
21. AUTOMATIC TRANSMISSION PARK
MECHANISM

22. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
23. ENGINE COOLANT LEVEL
Check that the coolant level is between the
LEVEL lines on the see±through reservoir at
normal temperature (20°C (68°F)).
24. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean
and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or
loose connections.
25. BATTERY ELECTROLYTE LEVEL
Check the indicator.
When the indicator color is blue, the condition
is satisfactory. A red color indicates that dis-
tilled water must be added, and white indi-
cates that charging is necessary.
26. BRAKE FLUID LEVEL
Check that the brake fluid level is near the up-
per level line on the see±through reservoir.27. ENGINE DRIVE BELT
Check drive belt for fraying, cracks, wear or
oil contamination.
28. ENGINE OIL LEVEL
Check that level on the dipstick with the en-
gine turned off.
29. POWER STEERING FLUID LEVEL
Check the level on the dipstick.
The level should be in the ºHOTº or ºCOLDº
range depending on the fluid temperature.
30. A U TO M AT I C TRANSMISSION FLUID
LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking and
foot brake applied, shift the selector into all
positions from ºPº to ºLº, and then shift into ºPº
position.
(c) Turn and pull out the dipstick and wipe off the
fluid with a clean rag.
Re±insert the dipstick fully and check that the
fluid level is in the ºHOTº range.
(d) Perform this check with the fluid at normal
driving temperature (70±80°C (158±176°F)).
If the level is at the low side, add fluid.
NOTICE: Do not overfill.
HINT: Wait about 30 minutes before checking
the fluid level after extended driving at high
speeds in hot weather, driving in heavy traffic
or with a trailer.
31. EXHAUST SYSTEM
Visually inspect for cracks, holes or loose
supports.
If any change in the sound of the exhaust or
smell of the exhaust fumes is noticed, have
the cause located and correted. MA±18
