5) Rebore and hone cylinder to calculated dimension.
NOTE:
Before reboring, install all main bearing caps in place and
tighten to specification to avoid distortion of bearing bores.
6) Measure piston clearance after honing.
INSTALLATION
NOTE:

All parts to be installed must be perfectly clean.

Be sure to oil crankshaft journals, journal bearings, thrust
bearings, crankpins, connecting rod bearings, pistons, pis-
ton rings and cylinder bores.

Journal bearings, bearing caps, connecting rods, rod bear-
ings, rod bearing caps, pistons and piston rings are in com-
bination sets. Do not disturb such combination and make
sure that each part goes back to where it came from, when
installing.
1) Install main bearings to cylinder block.
One of two halves of main bearing (2), has an oil groove (3).
Install it to cylinder block (1), and the other half without oil groove
to bearing cap.
Make sure that two halves are painted in the same color.
2) Install thrust bearings (1) to cylinder block between No.2 and
No.3 cylinders. Face oil groove (2) sides to crank webs.

1. Short bolts
2. Long bolts

3) Install crankshaft to cylinder block.
4) Install bearing cap to cylinder block, making sure to point arrow
mark (on each cap) to crankshaft pulley side. Fit them sequen-
tially in ascending order, 1, 2, 3, 4 and 5, starting from pulley side.
After installing bearing cap stiffeners, tighten bearing cap bolts
in such order as shown in figure a little at a time and repeat it till
they are tightened to specified torque.

correct use.
After installing oil seal housing, gasket edges might bulge out;
if so, cut them off to make them flush with cylinder block and oil
seal housing.
6) Install oil pump.
Refer to item “Oil pump” for installation of oil pump.
7) Install flywheel (M / T model) or drive plate (A / T model).
Using special tool, lock flywheel or drive plate, and torque its
bolts to specification.

8) Install pistons and connecting rods as previously outlined.
9) Install oil pump strainer and oil pan as previously outlined.
10) Install cylinder head assembly to cylinder block as previously
outlined.
11) Install camshaft, crankshaft timing belt pulley, timing belt,
crankshaft pulley, water pump pulley, etc., as previously out-
lined.
12) Install clutch to flywheel (for M / T vehicle). For clutch installa-
tion, refer to “CLUTCH” section.
13) Install engine mountings and brackets.
Refer to tightening torque for INSTALLATION of “ENGINE AS-
SEMBLY” in this section.
14) Install engine with transmission to vehicle as previously out-
lined.

6B-2 ENGINE COOLING
GENERAL DESCRIPTION
COOLING SYSTEM CIRCULATION
During engine warm-up (thermostat closed), the water pump discharges coolant into the water jacket chamber
adjacent to No.1 cylinder. Coolant then flows through the cylinder block and the cylinder heat. Coolant then returns
to the water pump through intake manifold, heater inlet hose, heater unit, heater outlet hose, and water intake pipe.
During normal temperatures (thermostat open), coolant takes the same basic route but is now allowed to flow past
the thermostat, the inlet hose and the radiator, and then back to the water pump through the outlet hose and the
water intake pipe.

ENGINE COOLING 6B-9
WATER PUMP
1) Disconnect negative cable at battery.
2) Drain cooling system.
3) Remove timing belt and tensioner according to procedure de-
scribed in “TIMING BELT AND TENSIONER” of Section 6A or
6A1.
4) Remove water pump belt adjusting arm.
5) Remove water pump assembly (1).
INSPECTION
NOTE:
Do not disassemble water pump.
If any repair is required on pump, replace it as assembly.
Rotate water pump by hand to check for smooth operation.
If pump does not rotate smoothly or makes abnormal noise, replace
it.
INSTALLATION
1) Install new pump gasket to cylinder block.
2) Install water pump to cylinder block.
Tightening Torque
(a): 12 N
.m (1.2 kg-m, 9.0 lb-ft)
3) After installing water pump, install rubber seal (1) between water
pump and oil pump, and another between water pump and cylin-
der head.
4) Install timing belt tensioner, timing belt and timing belt outside
covers according to procedure described in “TIMING BELT AND
TENSIONER” of Section 6A or 6A1.
NOTE:
Special care must be used when installing belt tensioner
and timing belt.
Torque each bolt and nut to specification.
Before installing outside covers, check to make sure that
cover seal is fitted in groove of each cover properly.

1. Throttle body
2. Fuel feed hose
NOTE:
Before starting engine, place transmission gear shift lever in
“Neutral” (shift selector lever to “P” range for A/T model), and
set parking brake and block drive wheels.
1) Warm up engine to normal operating temperature.
2) Set tachometer.
3) Check idle speed with A/C OFF.
If idle speed is not within specified range, check idle speed con-
trol system and any other system and parts which might affect
idle speed. Refer to “Engine Diagnosis of Section 6” for inspec-
tion.
Engine idle speed: 850
50 r/min
NOTE:
Idle speed is not adjustable manually. If it is out of its speci-
fied range, there is a faulty condition somewhere. Check
each of related systems and parts.
AIR AND FUEL DELIVERY SYSTEM
FUEL PRESSURE
INSPECTION
1) Relieve fuel pressure, referring to Section 6.
2) Separate air cleaner assembly from throttle body and shift its
position.
3) Disconnect fuel feed hose from throttle body.
CAUTION:
A small amount of fuel may be released after fuel line is
disconnected.
In order to reduce chance of personal injury, cover fitting
to be disconnected with a shop cloth. Place that cloth in
an approved container when disconnection is com-
pleted.
4) Connect special tools and hose between throttle body and fuel
feed pipe as shown in figure, and clamp hoses securely to en-
sure no leaks occur during checking.

IDLE SPEED / IDLE AIR CONTROL (IAC) DUTY
INSPECTION
Before idle speed / IAC duty check, make sure of the following.

Lead wires and hoses of Electronic Fuel Injection and engine
emission control systems are connected securely.

Accelerator cable has some play, that is, it is not tight.

Valve lash is checked and adjusted according to maintenance
schedule.

Ignition timing is within specification.

All accessories (wipers, heater, lights, A / C, etc.) are out of ser-
vice.

Air cleaner has been properly installed and is in good condition.

No abnormal air inhaling from air intake system.
After above items are all confirmed, check idle speed and IAC duty
as follows.
NOTE:
Before starting engine, place transmission gear shift lever in
“Neutral” (shift selector lever to “P” range for A / T vehicle),
and set parking brake and block drive wheels.
1) Connect SUZUKI scan tool (1) to DLC with ignition switch OFF,
if it is available.
2) Warm up engine to normal operating temperature.
3) Check engine idle speed and “IAC duty” as follow:
Select “Data List” mode on scan tool to check “IAC duty” and en-
gine speed.
Special Tool
(A): 09931-76011 (SUZUKI scan tool)
(B): Mass storage cartridge
(C): 09931-76030 (16 / 14 pin DLC cable)
If duty and/or idle speed is out of specifications, inspect idle air
control system referring to Diagnostic Flow Table B-4 IDLE AIR
CONTROL SYSTEM CHECK in Section 6.

4) Check that 875 ± 50 r / min. idle speed is obtained with lighting
switch ON and heater blower switch in 2 – 4 position.
If not, check “Electric load (+)” circuit and “Heater blower switch
signal” circuit referring to “ELECTRONIC CONTROL SYSTEM”
in this section and idle air control system.
5) Check that specified engine idle speed is obtained with A / C ON
if vehicle is equipped with A / C.
