2000 SUZUKI SWIFT engine oil

Don’t apply force
6A-16 ENGINE MECHANICAL (G10, 1-CAM 6-VALVES ENGINE)
6) Remove camshaft housings from cylinder head.
7) Remove camshaft from cylinder head.
8) Remove valve lash adjuster from cylinder head.
NOTE:

Never disassemble hydraulic valve lash adjuster.

Don’t apply force to body of adjuster, for oil in high pres-
sure chamber in adjuster will leak.

Immerse removed adjuster (2) in clean engine oil (1) and
keep it there till reinstalling it so as to prevent oil leakage.
If it is left in air, place it with its bucket body facing down.
Don’t place on its side or with bucket body facing up.

Indicates position from timing belt
side. Install in numerical order
starting from timing belt side.

Indicates direction of housing.
Install so that arrow is directed
toward timing belt side.

INSTALLATION
1) Before installing valve lash adjuster to cylinder head, fill oil pas-
sage of cylinder head (1) with engine oil according to the follow-
ing procedure.
Pour engine oil through camshaft journal oil holes (2) and check
that oil comes out from oil holes in sliding part of valve lash ad-
juster.
2) Install lash adjuster to cylinder head.
Apply engine oil around valve lash adjuster and then install it to
cylinder head.
3) Install camshaft to cylinder head.
After applying engine oil to camshaft journal and all around cam,
set camshaft to cylinder head so that camshaft timing belt pulley
pin hole (1) in camshaft is at lower position.
4) Install camshaft housing to camshaft and cylinder head.

Apply engine oil to sliding surface of each housing against
camshaft journal.

Apply sealant to mating surface of No.1 and No.3 housings
which will mate with cylinder head.
“A”: Sealant 99000-31110

Embossed marks are provided on each camshaft housing, in-
dicating position and direction for installation.
Install housing as indicated by these marks.

As camshaft housing No.1 (1) retains camshaft in proper
position as to thrust direction, make sure to first fit No.1 hous-
ing to No.1 journal of camshaft securely.

After applying engine oil to housing bolts, tighten them tem-
porarily first. Then tighten them by following sequence as
shown in figure.
Tighten a little at a time and evenly among bolts and repeat
tightening sequence three to four times before they are tight-
ened to specified torque.

.m (1.1 kg-m, 8.0 lb-ft)
5) Install camshaft oil seal.
After applying engine oil to oil seal lip, press-fit camshaft oil
seal till oil seal surface becomes flush with housing surface.
6) Install camshaft timing belt pulley (1) to camshaft (2) after
installing dwell pin to camshaft.
With locking camshaft as shown in figure, tighten pulley bolt to
specified torque.
Tightening Torque
(b): 60 N
.m (6.0 kg-m, 43.5 lb-ft)
7) Install cylinder head cover to cylinder head as previously out-
lined.
8) Install timing belt, timing belt outside cover, crankshaft pulley,
water pump pulley and water pump belt as previously outlined.
9) Install distributor case and distributor.
Refer to Section 6F for installation.
10) Install air cleaner assembly as previously outlined.
11) Connect negative cable at battery.
12) Adjust ignition timing.
Refer to Section 6F for adjustment.

6A-20 ENGINE MECHANICAL (G10, 1-CAM 6-VALVES ENGINE)
CAUTION:

Don’t turn camshaft or start engine (i.e., valves should not be operated) for about half an hour after
reinstalling hydraulic valve lash adjusters and camshaft. As it takes time for valves to settle in place,
operating engine within half an hour after their installation may cause interference to occur between
valves and piston.

If air is trapped in valve lash adjuster, valve may make tapping sound when engine is operated after
valve lash adjuster is installed. In such a case, run engine for about half an hour at about 2,000 – 3,000
r / min., and then air will be purged and tapping sound will cease. Should tapping should not cease,
it is possible that valve lash adjuster is defective. Replace it if defective.
If defective adjuster can’t be located by hearing among 6 of them, check as follows.
1) Stop engine and remove cylinder head cover.
2) Push adjuster downward by hand (with less than 15 kg or 33 lbs force) when cam crest is not on
adjuster to be checked and check if clearance exists between cam and adjuster. If it does, adjuster
is defective and needs replacement.
VALVE LASH ADJUSTER NOISE DIAGNOSIS
In case of the followings, valve lash adjuster noise may be caused by air trapped into valve lash adjusters.

Vehicle is left for 24 hours or more.

Engine oil is changed.

Hydraulic lash adjuster is replaced or reinstalled.

Engine is overhauled.
If noise from valve lash adjusters is suspected, perform the following checks.
1) Check engine oil for the followings.

Oil level in oil pan
If oil level is low, add oil up to Full level hole on oil level gauge.

Oil quality
If oil is discolored, or deteriorated, change it.
For particular oil to be used, refer to Section 0B.

Oil leaks
If leak is found, repair it.

Oil pressure (refer to Oil Pressure Check in this section)
If defective pressure is found, repair it.
2) Run engine for about half an hour at about 2,000 to 3,000 r / min., and then air will be purge and tapping sound
will cease.
3) Should tapping sound not cease, it is possible that hydraulic valve lash adjuster is defective.
Replace it if defective.
If defective adjuster can’t be located by hearing among 16 of them, check as follows.
a) Stop engine and remove cylinder head cover.
b) Push adjuster downward by hand (with less than 20 kg or 44 lbs. Force) when cam crest is not on adjuster
to be check if clearance exists between cam and adjuster.
If it does, adjuster is defective and needs replacement.

INSPECTION
Valve Guides
Using a micrometer and bore gauge, take diameter readings on
valve stems and guides to check stem-to-guide clearance.
Be sure to take reading at more than one place along the length of
each stem and guide.
If clearance exceeds limit, replace valve and valve guide.
