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.

MAINTENANCE
COOLANT
The coolant recovery system is standard. The coolant in the radiator expands with heat, and the overflow is col-
lected in the reservoir tank.
When the system cools down, the coolant is drawn back into the radiator.
The cooling system has been filled at the factory with a quality coolant that is either 50 / 50 mixture of water and
GOLDEN CRUISER 1200 (ethylene glycol antifreeze.) or 30 / 70 mixture of water and GOLDEN CRUISER 1200.
The 50 / 50 mixture coolant solution provides freezing protection to – 36C (– 33F), the 30 / 70 mixture coolant solu-
tion provides freezing protection to – 16C (3F).
When changing the engine coolant, use mixture of 50% water and 50% GOLDEN CRUISER 1200 for the market
where ambient temperature falls lower than – 16C (3F) in winter and mixture of 70% water and 30% GOLDEN
CRUISER 1200 for the market where ambient temperature doesn’t fall lower than – 16C (3F).
NOTE:
Alcohol or methanol base coolant or plain water alone should not be used in cooling system at any time
as damage to cooling system could occur.
Even in a market where no freezing temperature is anticipated, mixture of 70% water and 30% ethylene
glycol antifreeze (Antifreeze / Anticorrosion coolant) should be used for the purpose of corrosion protec-
tion and lubrication.

4) Remove thermostat (1).
INSPECTION
1) Make sure that air bleed valve (1) of thermostat is clean.
Should this valve be clogged, engine would tend to overheat.
2) Check to make sure that valve seat is free from foreign matters
which would prevent valve from seating tight.
3) Check thermostatic movement of wax pellet as follows:
Immerse thermostat (1) in water, and heat water gradually.
Check that valve starts to open at specific temperature.
If valve starts to open at a temperature substantially below or
above specific temperature, thermostat unit should be re-
placed with a new one. Such a unit, if reused, will bring about
overcooling or overheating tendency.
INSTALLATION
1) When positioning thermostat on thermostat case, be sure to
position it so that air bleed valve comes uppermost and into the
recession of thermostat case.
2) Install thermostat cap to thermostat case. When installing cap,
align arrow marks on cap and case.
3) Fill cooling system.
4) Connect negative cable.
5) After installation, check each part for leakage.

WARNING:
For vehicles equipped with a Supplemental Inflatable Restraint Air Bag System:
Service on or around Air Bag System Components or Wiring must be performed only by an authorized
Suzuki dealer. Please observe all WARNINGS and SERVICE PRECAUTIONS in Section 9J under “On-
Vehicle Service” and the Air Bag System Component and Wiring Location view in Section 9J before
performing service on or around Air Bag System Components or Wiring. Failure to follow WARNINGS
could result in unintended air bag deployment or could render the air bag inoperative. Either of these
two conditions may result in severe injury.
SDM can maintain sufficient voltage to cause a deployment of air bags for up to 15 seconds after igni-
tion switch is turned to “LOCK” position, battery is disconnected or fuse powering SDM is removed.
Work must be started after 15 seconds from the time.
NOTE:
For the descriptions for vehicle without warm up three way catalytic converter (WU TWC), refer to the same
section of the Service Manual mentioned in the FOREWORD of this manual.
