Oil Jet
INSPECTION (For gear train)
Make sure that the holes are not clogged. Clean them with a wire
if necessary.
Oil jet has to be installed with oil hole facing crank gear and
idler gear.
INSPECTION (For piston)
1. Blow through outlet of oil jet and make sure that air comes outof inlet.
2. Push cut-off valve of oil jet bolt with a clean resin or brass rod and make sure that cut-off valve moves smoothly with proper
repulsion.
When installing oil jet, align oil jet's boss with hole on cylin-
der block. Oil jet bolt:

System Inspection
CHECKING HOSES
Check hoses for proper attachment, leaks, cracks, damage, loose
connections, chafing and deterioration.
CHECKING RADIATOR CAP
To check radiator cap, apply pressure to the cap with a cap tester.Radiator cap relief pressure:78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
CHECKING COOLING SYSTEM FOR LEAKS
Appear pressure to the cooling system by means of a tester to
check for leakage. Testing pressure:157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher than the specified pressure may cause radiator dam-
age.

Water Pump
REMOVAL AND INSTALLATION
Drain coolant from drain plugs on cylinder block and radiator.Cylinder block drain plug:
(Use proper sealant)
:20-29N ×m (2.0 - 3.0 kg-m, 14 - 22 ft-lb)
CAUTION:
I When removing water pump assembly, be careful not to
spill coolant on drive belt.
I Water pump cannot be disassembled and should be
replaced as a unit.
I Always replace with new gasket.
I After installing water pump, connect hose and clamp
securely, then check for leaks using radiator cap tester.

INSPECTION
1. Check for badly rusted or corroded body assembly and vane.
2. Check the water pump bushing for excessive end play andirregular movement.
3. Check fan coupling for rough operation, oil leakage or bent bimetal.
The water pump and fan coupling cannot be disassembled and
should be replaced as a unit.

I Be careful not to spill coolant over engine compartment.
Place a rag to absorb coolant.
INSPECTION
1. Check for valve seating condition at ordinary temperatures. It
should seat tightly.
2. Check valve opening temperature and maximum valve lift.
Valve opening temperature ÉC (ÉF) 88 (190)
Max. valve lift mm/ÉC (in/ÉF)8/100
(0.315/212)
3. Then check if valve closes at 5ÉC (9ÉF) below valve opening temperature.

Cooling Fan
DISASSEMBLY AND ASSEMBLY
IProper alignment of components is essential.
Improper alignment will cause them to wobble and may even-
tually cause the fan to separate from the water pump causing
extensive damage.
I If front mark q
Fis present, install fan so that side marked qF
faces the front.
INSPECTION
Check fan coupling for irregular operation, oil leakage or bent
bimetal.
