NOTE:
At this time, be very careful not to exert force to where
heated oxygen sensor and its lead wire are connected.
4) Reinstall oil filter.
5) Start engine and warm it up to normal operating temperature.
6) After warming up, raise engine speed to 4,000 r / min and mea-
sure oil pressure.
Oil pressure specifications: 270 – 370 kPa
(2.7 – 3.7 kg / cm

38.4 – 52.6 psi) at
4,000 r / min (rpm)
7) After checking oil pressure, stop engine and remove oil filter
and oil pressure gauge.
8) Before reinstalling oil pressure switch (1), be sure to wrap its
screw threads with a sealing tape and tighten switch to speci-
fied torque.
NOTE:
If sealing tape edge is bulged out from screw threads of
switch, cut it off.

9) After oiling oil filter “O” ring (rubber gasket), screw oil filter on
oil filter stand by hand until filter “O” ring contacts mounting sur-
face.
CAUTION:
To tighten oil filter properly, it is important to accurately
identify the position where filter “O” ring first contacts
mounting surface.
10) Tighten filter (1) 3 / 4 (270) turn from the point of contact with
mounting surface using an oil filter wrench.

CAUTION:
To prevent oil leakage, make sure that oil filter is tight,
but do not overtighten it.
11) After installing oil filter, start engine and check oil filter for oil
leakage.

Direction of crankshaft
ENGINE MECHANICAL (G10, 1-CAM 6-VALVES ENGINE) 6A-13
3) Check that timing mark (3) on camshaft timing belt pulley (1) is
aligned with “V” mark (2) on cylinder head cover (4). If not, align
two marks by turning camshaft but be careful not to turn it more
than its allowable turning range which is described on previous
page.
4) Check that punch mark (2) on crank timing belt pulley (4) is
aligned with arrow mark (3) on oil pump case. If not, align two
marks by turning crankshaft but be careful not to turn it more
than its allowable turning range which is described on previous
page.
5) With two sets of marks aligned, install timing belt (1) on two pul-
leys in such a way that the drive side of belt is free of any slack,
and with tensioner plate pushed up by finger.
And then install tensioner spring and spring damper (2) as
shown in figure, and handtighten tensioner stud.
NOTE:

When installing timing belt, match arrow mark (
) on
timing belt with rotating direction of crankshaft.

In this state, No.1 piston is at top dead center of compres-
sion stroke.
6) To take up slack of timing belt, turn crankshaft two rotations
clockwise after installing it. After making sure that belt is free
from slack, tighten tensioner stud (1) first and then tensioner bolt
(2) to each specified torque.
Then confirm again that two sets of marks are aligned respec-
tively.
