REMOVAL SERVICE POINTS

<<A>> SURGE TANK ASSEMBLY REMOVAL
If the clearance is too narrow when removing the surge tank, jack up the transmission assembly to secure a working space.

<<B>> FUEL HIGH-PRESSURE HOSE DISCONNECTION

1.
caution Be careful not to twist the fuel high-pressure hose because it is made of resin.
Insert the (-) driver or similar tool (width: 6 mm, thickness: 1 mm) to the retainer of the fuel high-pressure hose connector.

2.Turn the (-) driver inserted into the retainer by 90 degrees, push up the retainer, and then unlock the fuel high-pressure hose connector.
3.Disconnect the fuel high-pressure hose from the fuel delivery pipe.

<<C>> FUEL DELIVERY PIPE, FUEL HIGH-PRESSURE HOSE AND FUEL INJECTOR ASSEMBLY REMOVAL
caution Do not drop the fuel injector.
Remove the fuel delivery pipe and fuel high-pressure hose with the fuel injector assembly attached to it.

INSTALLATION SERVICE POINTS

>>A<< INLET MANIFOLD GASKET INSTALLATION

Install the inlet manifold gasket with the protrusions in the position illustrated.

>>B<< INLET MANIFOLD INSTALLATION

>>C<< FUEL HIGH-PRESSURE HOSE CONNECTION

1.Pull up the lock of fuel high-pressure hose to unlock before installing.

2.
caution After connecting the fuel high-pressure hose, slightly pull it in the pull-out direction to check that it is installed firmly. In addition, check that there is approximately 1 mm play.
Install the fuel high-pressure hose to the fuel delivery pipe securely and push the lock of fuel high-pressure hose downward and lock thoroughly.

>>D<< SURGE TANK GASKET/SURGE TANK ASSEMBLY INSTALLATION

1.Temporarily install the positioning bolt for the surge tank gasket (M8×1.25 mm, length 25 mm) to the position shown in the figure from under side.

2.Install the surge tank gasket with the protrusions in the position illustrated.
3.Install the surge tank assembly taking care not to let the surge tank gasket deviate from its position.
4.Remove the positioning bolt for surge tank gasket that was temporarily installed in step 1.

>>E<< EXHAUST MANIFOLD EGR PIPE GASKET INSTALLATION

Install the exhaust manifold EGR pipe gasket as its protrusion is in the direction shown.
