3. DISCONNECTION OF FUEL HIGH PRESSURE HOSE
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.
For information concerning the bleeding of the residual
pressure, refer to GROUP
13-On-Vehicle Inspection of
MFI
Components.
5. REMOVAL OF RADIATOR UPPER HOSE Make mating marks on the radiator hose and hose clamp,
and then disconnect the radiator hose.
28. REMOVAL OF ENGINE MOUNTING BRACKET
Jack up the vehicle after placing a wooden block between the jack and the engine’s oil pan.
Caution
Jack up carefully, so as not to apply an excessive
load to the various parts.
Remove the engine mount bracket.
32. REMOVAL OF CAMSHAFT SPROCKET
(1) Rotate the crankshaft and align the timing mark.
(2) Remove the camshaft sprocket (with the timing belt attached), and place on the timing belt front lower cover.
Caution
After removing the camshaft sprocket, be sure not
to rotate the crankshaft.

(2) Using the special tool, tighten the bolts in the order
shown in two or three steps.
5. INSTALLATION OF RADIATOR UPPER HOSE
Align the mating marks (of the radiator hose and hoseclamp), and then, while applying force in the direction of
the arrow in the illustration, seat the hose clamp to the
trace marks (on the hose) remaining from the prior connection.
Caution Be sure to install the hose clamp at the trace marks (on
the hose) remaining from the prior connection.
3. CONNECTION OF FUEL HIGH PRESSURE HOSE
When connecting the high-pressure fuel hose to the fuel rail, apply a coating of engine oil to the hose union, and in-
sert so that the O-ring is not damaged.

(3) Turn the crankshaft clockwise by two teeth of the
camshaft sprocket.
Caution
As the purpose of this procedure is to apply the
proper amount of tension on the timing belt, be sure
not to rotate the crankshaft counter-clockwise or
place pressure on the belt to check the amount of
tension.

(4) Apply force on tensioner toward turning direction, (inthe direction of the arrow) such that no portion of the
belt raises out in portion A, place the belt on the
camshaft sprocket such that the belt sprocket teeth
are fully engaged.
(5) Tighten the tensioner installation bolt and tensioner spacer in that order.
Caution
If the tensioner spacer is tightened first, the ten-
sioner will rotate with it and belt tension be thrown
out of adjustment. Always tighten the bolt first.

(6) Check to see that the clearance between the outside of the belt and the cover are within the standard value
by grasping the tension side (between the camshaft
sprocket and oil pump sprocket) of the centre part of
the timing belt between the thumb and index finger.
