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.

Thermostat Removal and InstallationS7RS0B1606007
Removal1) Drain coolant referring to “Cooling System Draining”.
2) Remove intake manifold referring to “Intake Manifold Removal and Installa tion in Section 1D”.
3) Remove generator referring to “Generator Dismounting and Remounting in Section 1J”.
4) Disconnect water hose (1) and heater hose (2) from each pipe.
5) Remove thermostat case (3) with thermostat cap (4)
and water inlet pipe (5).
6) Remove water inlet pipe with thermostat cap from thermostat case.
7) Remove thermostat from thermostat case (3).
Installation
Reverse removal procedure for installation noting the
following points.
• Install thermostat cap (1) to thermostat case (2) by aligning match mark (3) of thermostat case with air
bleed valve (4) of the thermostat (5).
• Use new O-rings when installing.
• Adjust water pump belt tension referring to “Water Pump / Generator Drive Belt Tension Inspection and
Adjustment in Section 1J”.
• Adjust A/C compressor belt tension referring to “Compressor Drive Belt Inspection and Adjustment in
Section 7B” or “Compressor Drive Belt Inspection and
Adjustment in Section 7B”. • Refill cooling system referrin
g to Step 7) to 22) of
“Cooling System Flush and Refill”.
• Verify that there is no coolant leakage at each connection.
Thermostat InspectionS7RS0B1606008
• Make sure that air bleed valve (1) of thermostat is clean.
• Check to make sure that va lve seat (2) is free from
foreign matters which would prevent valve from
seating tight.
• Check thermostat seal (3) for breakage, deterioration or any other damage.
• 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 specific temperature.
Temperature at which valve begins to open
80 – 84 °C (176 – 183 °F)
Temperature at which valve become fully open
95 – 97 °C (203 °F)
Va l v e l i ft
More than 8 mm at 95 °C (203 ° F)
If valve starts to open at a temperature substantially
below or above specific temperature, thermostat unit
should be replaced with a new one. Such a unit, if
reused, will bring about ov ercooling or overheating
tendency.
