2000 SUZUKI SWIFT oil type

ENGINE MECHANICAL (M13 ENGINE) 6A1-3
ENGINE LUBRICATION
The oil pump is of a trochoid type, and mounted on the crankshaft. Oil is drawn up through the oil pump strainer
and passed through the pump to the oil filter.
The filtered oil flows into 2 paths in cylinder block.
In one path, oil reaches the crankshaft journal bearings. Oil from the crankshaft journal bearings is supplied to
the connecting rod bearings by means of intersecting passages drilled in the crankshaft, and then injected from
the big end of connecting rod to lubricate piston, rings, and cylinder wall.
In other path oil goes up to the cylinder head and lubricates valves and camshafts, etc., after passing through
the internal oilway of camshafts.
An oil relief valve is provided on the oil pump. This valve starts relieving oil pressure when the pressure exceeds
about 400 kPa (4.0 kg/cm
2, 56.9 psi).

ON-VEHICLE SERVICE
IGNITION SPARK TEST
1) Disconnect all injector couplers (1) from injectors.
2) Remove spark plug and check it for condition and type refer-
ring to “Spark Plugs” in this section.
3) If OK, connect ignition coil coupler to ignition coil assembly
and connect spark plug to ignition coil assembly or high-ten-
sion cord. Ground spark plug.
4) Crank engine and check if each spark plug sparks.
5) If no spark is emitted, inspect the related parts as described
under “Diagnosis” earlier in this section.
HIGH-TENSION CORDS
1) Remove air intake pipe and cylinder head upper cover.
2) Disconnect high-tension cords (2) from ignition coil assem-
blies (1) while gripping each cap.
3) Pull out high-tension cords from spark plugs while gripping
each cap.
4) Measure resistance of high-tension cord (1) by using ohm-
meter.
High-tension cord resistance
: 4 -10 k
Ω/m (1.2 - 3.0 kΩ/ft)
5) If resistance exceeds specification, replace high-tension
cord(s). WARNING:
Without disconnection of injector couplers, combustible
gas may come out from spark plug holes during this test
and may get ignited in engine room.
CAUTION:
Removal of high-tension cords together with clamps
will be recommended so as not to damage their inside
wire (resistive conductor).
For the same reason, pull out each connection by grip-
ping cap portion.

6F1-6 IGNITION SYSTEM (ELECTRONIC IGNITION SYSTEM)
6) Install high-tension cords (2) to spark plugs and ignition coil
assemblies (1) while gripping each cap.
SPARK PLUGS
1) Remove air intake pipe and cylinder head upper cover.
2) Pull out high-tension cords by gripping their caps and then
remove ignition coil assemblies referring to IGNITION COIL
ASSEMBLY in this section.
3) Remove spark plugs.
4) Inspect them for:
Electrode wear
Carbon deposits
Insulator damage
5) If any abnormality is found, adjust air gap, clean with spark
plug cleaner or replace them with specified new plugs.
For iridium/platinum spark plugs, replace them with new
plugs.
Spark plug air gap
“a” : 1.0 - 1.1 mm (0.040 - 0.043 in.)
Spark plug type
NGK : BKR6E-11, IFR5E11
DENSO : K20PR-U11 CAUTION:
Never attempt to use metal conductor high-tension
cords as replacing parts.
Insert each cap portion fully when installing high-ten-
sion cords.
NOTE:
NGK IFR5E11 is highly recommended for better engine
starting performance under -25°C(-13°F).
CAUTION:
When servicing the iridium/platinum spark plugs (slen-
der center electrode type plugs), do not touch the cen-
ter electrode to avoid damage to it. The electrode is not
strong enough against mechanical force as it is slen-
der and its material is not mechanically tough
Do not clean or adjust gap for the iridium/platinum
spark plugs.
