Engine Cooling System
General Description
Cooling System DescriptionS7RS0B1601001
The cooling system consists of the radiator cap, radiator, coolant reservoir, hoses, water pump, cooling fan and 
thermostat. The radiator is of tube-and-fin type.
Coolant DescriptionS7RS0B1601002
WARNING! 
• Do not remove radiator cap to check engine coolant level; check coolant visually at the see-through  coolant reservoir. Coolant should be added only to reservoir as necessary.
• As long as there is pressure in the cooling system, the temperature can be considerably higher than  the boiling temperature of the solution in the radiator without causing the solution to boil. Removal 
of the radiator cap while engine is hot and pressure is high will cause the solution to boil 
instantaneously and possibly with explosive force,  spewing the solution over engine, fenders and 
person removing cap. If the solution contains flammable anti-freeze such as alcohol (not 
recommended for use at any time), there is also the possibility of causing a serious fire.
• Check to make sure that engine coolant temperature is cold before removing any part of cooling  system.
• Also be sure to disconnect negative cable from battery terminal before removing any part.
 
The coolant recovery system is standard. The coolant in the radiator expands with heat, and the coolant is overflowed 
to the reservoir.
When the system cools down, the coolant is drawn back into the radiator.
The cooling system has be en filled with a quality coolant that is a 50/50 mixture  of water and ethylene glycol 
antifreeze.
This 50/50 mixture coolant solution  provides freezing protection to –36 °C (–33  °F).
• Maintain cooling system freeze protection at –36  °C (–33  °F) to ensure protection against corrosion and loss of 
coolant from boiling. This should be done even  if freezing temperatures are not expected.
• Add ethylene glycol base coolant when coolant has to be added because of coolant loss or to provide added  protection against freezing at temperature lower than –36  °C (–33  °F).
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.
• Coolant must be mixed with deminerated water or distilled water.

Precautions
Precautions on Fuel System ServiceS7RS0B1700001
WARNING! 
Before attempting service of any type on fuel system, the following should be always observed in 
order to reduce the risk of fire and personal injury.
• Disconnect negative cable at battery.
• Do not smoke, and place no smoking signs near work area.
• Be sure to have CO
2 fire extinguisher handy.
• Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot  heater).
• Wear safety glasses.
• To relieve fuel vapor pressure in  fuel tank, remove fuel filler cap from fuel filler neck and then 
reinstall it.
• As fuel feed line is still under high fuel pr essure even after stopping engine, loosening or 
disconnecting fuel feed line directly may cause dangerous spout of fuel. Before loosening or 
disconnecting fuel feed line, make sure to relieve fuel pressure referring to “Fuel Pressure Relief 
Procedure”.
• A small amount of fuel may be released when the fuel line is disconnected. In order to reduce the  risk of personal injury, cover a shop cloth to the fitting to be disconnected. Be sure to put that cloth 
in an approved container after disconnecting.
• Never run engine with fuel pump relay disconnected when engine and exhaust system are hot.
• Note that fuel hose connection varies with each type of pipe. Be sure to connect and clamp each  hose correctly referring to “Fuel Hose Disconnecting and Reconnecting”.
After connecting, make sure that it has no twist or kink.
• When installing inje ctor or fuel feed pipe, lubr icate its O-ring with gasoline.
 
General Description
Fuel System DescriptionS7RS0B1701001
CAUTION! 
This engine requires the unleaded fuel only. 
The leaded and/or low lead fuel can result in 
engine damage and reduce the effectiveness 
of the emission control system.
 
The main components of the fuel system are fuel tank, 
fuel pump assembly (with fuel  filter, fuel level gauge, fuel 
pressure regulator, fuel feed line and fuel vapor line.
For the details of fuel flow, refer to “Fuel Delivery System 
Diagram”.
Fuel Delivery System DescriptionS7RS0B1701002
The fuel delivery system consists of the fuel tank, fuel 
pump assembly (with built-in f uel filter and fuel pressure 
regulator), delivery pipe, injectors and fuel feed line.
The fuel in the fuel tank is pumped up by the fuel pump, 
sent into delivery pipe and injected by the injectors.
As the fuel pump assembly  is equipped with built-in fuel 
filter and fuel pressure regulator, the fuel is filtered and 
its pressure is regulated before being sent to the feed 
pipe.
The excess fuel at fuel pressure regulation process is 
returned back into the fuel tank.
Also, fuel vapor generated in fuel tank is led through the 
fuel vapor line into the EVAP canister.
For system diagram, refer to “Fuel Delivery System 
Diagram”.

Charging System
General Description
Battery DescriptionS7RS0B1A01001
The battery has three major functions in the electrical 
system.
• It is a source of electrical energy for cranking the  engine.
• It acts as a voltage stabilizer for the electrical system.
• It can, for a limited time, provide energy when the  electrical load exceeds the output of the generator.
Carrier and Hold-Down
The battery carrier should be in good condition so that it 
will support the battery securely  and keep it level. Before 
installing the battery, the ba ttery carrier and hold-down 
clamp should be clean and free from corrosion and 
make certain there are no parts in carrier.
To prevent the battery from shaking in its carrier, the 
hold-down bolts should be tight enough but not over-
tightened.
Electrolyte Freezing
The freezing point of electrolyte depends on its specific 
gravity. Since freezing may ruin a battery, it should be 
protected against freezing by keeping it in a fully 
charged condition. If a battery is frozen accidentally, it 
should not be charged until it is warmed.
Sulfation
If the battery is allowed to stand for a long period in 
discharged condition, the lead sulfate becomes 
converted into a hard, cryst alline substance, which will 
not easily turn back to the active material again during 
the subsequent recharging. “Sulfation” means the result 
as well as the process of that reaction. Such a battery 
can be revived by very slow charging and may be 
restored to usable condition but its capacity is lower than 
before. Built-In Indicator (If Equipped)
The battery has a built-in temperature compensated 
indicator in the top of the battery. This indicator is to be 
used with the following diagnostic procedure. When 
checking the indicator, make sure that the battery has a 
clean top. A light may be needed in some poorly-lit 
areas.
Three types of indication available under normal 
operation are as follows.
•
Green dot
Battery is sufficiently charged for testing.
• Dark
Battery must be charged before testing. If there is a 
cranking complaint, battery should be tested as 
described in “Battery Inspection”. Charging and 
electrical systems should also  be checked at this time.
• Clear
This means that fluid level is below the bottom of 
hydrometer. Its possible  cause is excessive or 
prolonged charging, a broken case, excessive tipping 
or normal battery deteriorat ion. When the battery is 
found in such condition, it  is possible that high 
charging voltage is caused by the faulty charging 
system and therefore, charging and electrical systems 
need to be checked. If there is a trouble in cranking 
and its cause lies in the battery, it should be replaced.

Charging System Circuit
The generator features solid state regulator that it mounted inside the generator. All regulator components are 
enclosed into a solid mold, and this unit along with the brus h holder assembly is attached to the rear housing. The 
regulator voltage is being controlled by ECM under some cond itions while driving. Refer to “Generator Control System 
Description in Section 1A”.
The generator rotor bearings contain enough grease  to eliminate the need for periodic lubrication.
Two brushes carry current through the two slip rings to the  field coil mounted on the rotor, and under normal conditions 
will provide long period of  attention-free service.
The stator windings are assembled inside a laminate d core that forms part of the generator frame.
A rectifier bridge connected to the stator windings contains diodes, and electrically changes the stator AC. voltages to 
a D.C. voltage which appears at the generator output terminal.

General Description
Electronic Stability Program DescriptionS7RS0B4601006
Electronic Stability Program (ESP ®) is an auxiliary function  to enable the vehicle to av oid a danger safely while the 
vehicle is running, stopping or turning.
Electronic Stability Program (ESP ®) consists of following functions.
ESP ® is a registered trademark of Daimler Chrysler AG.
Antilock Brake System (ABS)
This system prevents tire locking which may occur when br ake is applied suddenly or on slippery roads. With this 
function, as the vehicle body is kept in the stable state an d tires unlocked, the driver can avoid any obstacle by turning 
the steering wheel.
Electronic Brake force Distribution (EBD)
This function distributes braking force of front and rear  wheels properly according to the vehicle load condition.
With this function, the braking force of the front and rear  wheels is controlled for the optimum effect to secure the 
maximum braking force regardless of the loadage.
Traction Control System (TCS)
This system controls the engine and brake to prevent the dr iving wheels from spinning at the time of starting and 
accelerating. Particularly, this fu nction is helpful for safe driving on muddy or icy roads. When ESP ® control module 
detects wheel spinning using information from the yaw rate  sensor and wheel speed sensor, it lower the engine torque 
by closing the electronic controlled thro ttle and controlling ignition. At the same time, brake is applied to the spinning 
tire.
Stability Control
This function controls the vehicle body  in the stable state by controlling the engine and braking so as to prevent the 
vehicle from over-steering or under-steering while turning.
When under-steering occurs, this function lowers the engine torque and applies brake to the inner rear wheel in the 
vehicle forward direction so as to pr event the vehicle from moving outward.
When over-steering occurs, this function applies brake to the  outer front wheel in the vehicle forward direction so as to 
prevent the vehicle from moving inward. Sensor Procedures required calibration
Steering angle sensor • Power is not su pplied to steering angle sensor. (battery, fuse and/or connector is 
removed.)
• Steering angle sensor is replaced.
• Power is not supplied to ESP ® control module. (battery,  fuse and/or connector is
