14. If any of fuel pressure measured in steps 10 to 13 is out of
specification, troubleshoot and repair according to the
table below.
SymptomProbable causeRemedy
DFuel pressure too low

15. Stop the engine and check change of fuel pressure gauge
reading. Normal if the reading does not drop within 2
minutes. If it does, observe the rate of drop and
troubleshoot and repair according to the table below.
SymptomProbable causeRemedy
Fuel pressure drops gradually after
engineisstopped
Leaky injectorReplace injector
engineisstopped
Leaky fuel regulator valve seatReplace fuel pressure regulator
Fuel pressure drops sharply
immediately after engine is stoppedCheck valve in fuel pump is held openReplace fuel pump
16. Release residual pressure from the fuel pipe line.
(Refer to P.13A-125.)
17. Remove the fuel pressure gauge and special tool from
the delivery pipe.
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
18. Replace the O-ring at the end of the fuel high pressure
hose with a new one. Furthermore, apply engine oil to
the new O-ring before replacement.
19. Fit the fuel high pressure hose over the delivery pipe
and tighten the bolt to specified torque.
Tightening torque: 5.0±1.0 N·m
20. Check for any fuel leaks by following the procedure in
step 7.
21. Disconnect the MUT-II.

Remove the delivery pipe (with the injectors attached to it).
Caution
Care must be taken, when removing the delivery pipe,
not to drop the injector.
INSTALLATION SERVICE POINT
"AAINJECTOR/FUEL PRESSURE REGULATOR
/HIGH-PRESSURE FUEL HOSE INSTALLATION
1. Apply a drop of new engine oil to the O-ring.
Caution
Be sure not to let engine oil enter the delivery pipe.
2. While turning the injector, high-pressure fuel hose and
fuel pressure regulator to the right and left, install the
delivery pipe, while being careful not to damage the O-ring.
After installing, check that the hose turns smoothly.
3. If it does not turn smoothly, the O-ring may be trapped,
remove the injector, high-pressure fuel hose or fuel
pressure regulator and then re-insert it into the delivery
pipe and check once again.
4. Tighten the high-pressure fuel hose and fuel pressure
regulator to the specified torque.

"AATHERMOSTAT INSTALLATION
Install the thermostat being careful not to fold over or scratch
the rubber ring.
Caution
Make absolutely sure that no oil is adhering to the rubber
ring of the thermostat. In addition, be careful not to fold
over or scratch the rubber ring when inserting. If the
rubber ring is damage, replace the thermostat.
"BARADIATOR UPPER HOSE CONNECTION
1. Insert each hose as far as the projection of the water
outlet fitting.
2. Align the mating marks on the radiator hose and hose
clamp, and then connect the radiator hose.
INSPECTION
THERMOSTAT CHECK
1. Immerse the thermostat in water, and heat the water while
stirring. Check the thermostat valve opening temperature.
Standard value:
Valve opening temperature: 80±1.5_C
2. Check that the amount of valve lift is at the standard value
when the water is at the full-opening temperature.
Standard value:
Full-opening temperature: 93_C
Amount of valve lift: 9.5 mm or more
NOTE
Measure the valve height when the thermostat is fully
closed, and use this measurement to calculate the valve
height when the thermostat is fully open.

PRESSURE CHECK
Caution
Two persons should be in the vehicle when the test is
conducted; the person in the passenger seat should read
the indications shown by the pressure meter.
1. Disconnect the hose (black) from the turbocharger waste
gate solenoid valve, and connect the pressure gauge
to the hose. Plug the nipple of the solenoid valve from
which the hose (black) has been disconnected.
2. Drive at full-throttle acceleration in second gear and then
measure the supercharging pressure when the engine
speed in about 3,000 r/min.
Standard value: 59 – 84 kPa
3. If the supercharging pressure deviates from the standard
value, check the following items for possible cause.
