When installing oil jet, align oil jet's boss with hole on cylin-
der block.
Oil jet bolt:
:30-40Nzm (3.1 - 4.1 kg-m, 22 - 30 ft-lb)
Turbocharger
+Before removing water tube, drain coolant ®rst.
+Be careful not to deform tubes.
+After installation, run engine for a few minutes, and check
for oil leakage.

Pull the negative pressure valve to open it. Check that it closes
completely when released.
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system by means of a tester to check
for leakage.
Testing pressure:
98 kPa (0.98 bar, 1.0 kg/cm
2, 14 psi)
CAUTION:
Use of pressure higher than the speci®ed value may cause
damage to radiator.
Water Pump
CAUTION:
+When removing water pump assembly, be careful not to
get coolant on drive belts.
+Water pump cannot be disassembled and should be
replaced as a unit.
+After installing water pump, connect hose and clamp
securely, then check for leaks using radiator cap tester.
REMOVAL
1. Drain coolant from radiator and cylinder block.
Cylinder block drain plug (Use proper sealant):
:34-44Nzm (3.5 - 4.5 kg-m, 25 - 33 ft-lb)
Refer to MA section (``Changing Engine Coolant'', ``ENGINE
MAINTENANCE'').
2. Remove radiator shroud.
3. Remove drive belts. Refer to MA section (``Checking Drive
Belts'').
4. Remove fan coupling with fan.
5. Remove water pump.

INSPECTION
1. Check for rusted or corroded body assembly and vane.
2. Check for excessive end play and rough operation.
INSTALLATION
+Remove liquid gasket from mating surface of pump housing
using a scraper.
Be sure liquid gasket in grooves is also removed.
+Remove liquid gasket from mating surface of cylinder block.
+Clean all traces of liquid gasket using white gasoline.
+Cut off tip of nozzle of liquid gasket tube at point shown in ®g-
ure.

+Apply a continuous bead of liquid gasket to mating surface of
pump housing as shown.
a. Be sure diameter of liquid gasket is within 2.0 to 3.0 mm
(0.079 to 0.118 in) dia. range.
b. Attach pump housing to cylinder block within ®ve minutes
of applying liquid gasket.
c. After installing pump housing, wait at least 30 minutes
before starting engine.
Thermostat
INSPECTION
1. Check valve seating condition at ordinary temperatures. It
should seat tightly.
2. Check valve opening temperature and maximum valve lift.
Valve opening temperature CÉ (ÉF) 82.0 (180)
Maximum valve lift mm/ÉC (in/ÉF) 10/90 (0.39/194)
3. Then check if valve closes at 5ÉC (9ÉF) below valve opening
temperature.
INSTALLATION
+Remove liquid gasket from mating surface of thermostat using
a scraper.
+Similarly, remove liquid gasket from mating surface of cylinder
block.
+Clean all traces of liquid gasket using white gasoline.

a. Be sure diameter of liquid gasket is within 2.0 to 3.0 mm (0.079
to 0.118 in).
b. Attach water inlet to cylinder block within ®ve minutes after
applying liquid gasket.
c. After installing water inlet, wait at least 30 minutes before re®ll-
ing coolant and starting engine.
