Oil Pressure Check
WARNING:
q Be careful not to burn yourself, as the engine and oil may
be hot.
q Oil pressure check should be done in ``Neutral position''
(M/T) or ``Parking position'' (A/T).
1. Check oil level.
2. Remove oil pressure switch.

ALC120

3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
Engine speed Approximate discharge pressure
rpm kPa (kg/cm2, psi)
Idle speed More than 59 (0.6, 9)
2,000 412 - 451 (4.2 - 4.6, 60 - 65)
If difference is extreme, check oil passage and oil pump for oil
leaks.
SLC926 6. Install oil pressure switch with sealant.

INSPECTION
Using a feeler gauge, straightedge and micrometers, check the
following clearances:
Unit: mm (in)
Body to outer gear radial clearance 1 0.114 - 0.200 (0.0045 - 0.0079)
Inner gear to outer gear tip clearance 2 Below 0.18 (0.0071)
Body to inner gear axial clearance 3 0.05 - 0.09 (0.0020 - 0.0035)
Body to outer gear axial clearance 4 0.050 - 0.110 (0.0020 - 0.0043)

SLC072B Inner gear to brazed portion of housing clear-
0.045 - 0.091 (0.0018 - 0.0036)
ance 5
q If the tip clearance ( 2 ) exceeds the limit, replace gear set.
q If body to gear clearances ( 1 , 3 , 4 , 5 ) exceed the limit,
replace oil pump body assembly.

SLC073B

SLC934A

REGULATOR VALVE INSPECTION
1. Visually inspect components for wear and damage.
2. Check oil pressure regulator valve sliding surface and valve
spring.
3. Coat regulator valve with engine oil. Check that it falls
smoothly into the valve hole by its own weight.
If damaged, replace regulator valve set or oil pump assembly.

SLC074B

OIL FILTER
The oil filter is a small, full-flow cartridge type and is provided with
a relief valve.
q The new and previous oil filter designs differ from each
other and are not interchangeable.
q Use Tool KV10115801 (J38956) for removing oil filter.

ENGINE COOLING SYSTEM

Cooling Circuit

SLC080B

System Check
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
Wrap a thick cloth around the cap. Slowly turn it a quarter turn
to allow built-up pressure to escape. Carefully remove the cap
by turning it all the way.

CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.

CHECKING COOLING SYSTEM FOR LEAKS
To check for leakage, apply pressure to the cooling system with a
tester.
Testing pressure: 157 kPa (1.6 kg/cm2, 23 psi)
CAUTION:
Higher pressure than specified may cause radiator damage.
SLC756A
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as
follows.
q Be careful not to bend or damage the radiator fins.
q When radiator is cleaned without removal, remove all sur-
rounding parts such as cooling fan, radiator shroud and horns.
q Tape the harness connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core ver-
tically downward.
2. Apply water again to all radiator core surfaces once per
minute.

ENGINE COOLING SYSTEM
System Check (Cont'd)
3. Stop washing when stains no longer flow out from the radia- GI
tor.
4. Blow air into the back side of radiator core vertically downward.
q Use compressed air lower than 5 kg/cm2 and keep distance MA
more than 30 cm (11.8 in).
5. Blow air again into all the radiator core surfaces once per
minute until no water sprays out. EM

CHECKING RADIATOR CAP EC
To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:
FE
Standard
78 - 98 kPa (0.8 - 1.0 kg/cm2, 11 - 14 psi)
Limit

CAUTION:
q When removing water pump assembly, be careful not to
get coolant on timing belt.
q Water pump cannot be disassembled and should be
replaced as a unit.
q After installing water pump, connect hose and clamp
securely. Check for leaks using radiator cap tester.
q To avoid deforming timing cover, make sure there is
adequate clearance between it and the hose clamp.

REMOVAL AND INSTALLATION
1. Drain coolant from drain plugs on both sides of cylinder block
and radiator. Refer to MA section (``Changing Engine Cool-
ant'').
