NISSAN TERRANO 2002 Service Repair Manual

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 out
of 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.

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:

:20-29N×m (2.0 - 3.0 kg-m, 14 - 22 ft-lb)
CAUTION:
IWhen removing water pump assembly, be careful not to
spill coolant on drive belt.
IWater pump cannot be disassembled and should be
replaced as a unit.
IAlways replace with new gasket.
IAfter 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 and
irregular 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.

INSPECTION
1. Check for valve seating condition at ordinary temperatures. It
should seat tightly.
2. Check valve opening temperature and maximum valve lift.
