INSPECTION
1) Make sure that air bleed valve (1) of thermostat is clear.
Should this valve be clogged, engine would tend to overheat.
2) Check valve seat for some foreign matters being stuck which
prevent valve from seating tight.
3) Check thermostatic movement of wax pellet as follows:
a) Immerse thermostat (1) in water, and heat water gradually.
b) Check that valve starts to open at specification temp.
c) If valve starts to open at a temperature substantially below
or above, thermostat unit should be replaced with a new
one.
Such a unit, if re-used, will bring about overcooling or over-
heating tendency.
Thermostat functional specification
INSTALLATION
1) When positioning the thermostat (2) on the thermostat case
(1), be sure to align its air breather valve (3) with mark (4).
2) Install thermostat cap (5) to thermostat case with align air
bleed valve and mark.
Then, tighten mounting bolts to specified torque.
Tightening torque
Thermostat cap bolts
(a) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
Thermostat case bolts
(b) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
3) Install intake manifold by referring to “Throttle Body and
Intake Manifold” in Section 6A1.
4) Fill the cooling system.

For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
Whether following systems (parts) are used in the particular vehicle or not depends on specifications.
Be sure to bear this in mind when performing service work.
EGR valve
Heated oxygen sensor (s) or CO adjusting resistor
Three way catalytic converter (TWC) and warm up three-way catalytic converter (WU-TWC)
