INSTALLATION SERVICE POINTS
INJECTORS INSTALLATION
(1) Apply a small amount of clean engine oil to the O-ring.
Caution
Donot let the engine oil get into the fuel rail.
(2) While
injector to the left and right, install it
to the fuel rail.
(3) Check to be sure that the injector turns smooth ly.
If it does not turn smoothly, the O-ring may be tra pped,
remove the injector and then, re-insert it into the fuel rail
and check once again.
FUEL PRESSURE REGULATOR
(1) Apply a small amount of clean engine oil to a n ew
and insert it to the fuel rail carefully.
Do not let the engine oil get into rail.
(2) If the fuel pressure regulator does
the O-ring may be folded.Then, remove regulator
to check the O-ring for damage.
(3) Tighten the regulator to the specified
Tightening torque: 8.8 Nm ‘(6.5
HIGH-PRESSURE FUEL
When connecting the high-pressure fuel hose to the fuel rail,
apply a small amount of clean engine oil to the hose union,
and then insert, being careful not
damage ‘the O-ring.,
Do not let the engine into

If the sound of the float valve moving (knocking so und) can
be heard when the valve assembly is gently shaken u p and
down, then the valve is okay.

ON-VEHICLE SERVICE
ENGINE COOLANT LEAK CHECK
1. Confirm that the coolant level is. up to the filter
Install a radiator cap tester and apply 160 (23 psi)
pressure, and then check for leakage from
radiator
hose or connections.
Caution
1. After testing, clean up all coolant seepagefrom
areas of leakage.
2.When the tester is removed, be careful not to spill
any coolant.
3.During tester usage, do not deform the filler neck
of the radiator.
2. If leakage is present, repair or replace the app ropriate
part.
RADIATOR CAP VALVE OPENING
CHECK
1.Use ‘a cap adapter to attach the radiator cap to the tester.
2. Increase the pressure until the indicator of the gauge
stops moving..

3.Replace the radiator cap if the reading does not re main
at or above the limit.
NOTE
Be sure that the radiator cap is clean before testing,
since rust or other foreign material on the radiato r cap
seal may cause an improper reading.
