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.

Coolant Level CheckS7RS0B1606002
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if radiator
cap is taken off too soon.

To check level, lift hood and look at “see-through”
coolant reservoir.
It is not necessary to remove radiator cap to check
coolant level.
When engine is cool, check coolant level in reservoir (1).
A normal coolant level should be between FULL mark
(2) and LOW mark (3) on reservoir (1).
If coolant level is below LOW mark (3), remove reservoir
cap (4) and add proper coolant to reservoir to bring
coolant level up to FULL mark (2).
NOTE
If proper quality antifreeze is used, there is
no need to add extra inhibitors or additives
that claim to improve system. They may be
harmful to proper operation of system, and
are unnecessary expense.

Engine Cooling System Inspection and
Cleaning
S7RS0B1606003
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if cap is
taken off too soon.

1) Check cooling system for leakage or damage.
2) Wash radiator cap and fille r neck with clean water by
removing radiator cap when engine is cold.
3) Check coolant for proper level and freeze protection.
4) Using a pressure tester (1), check system and radiator cap (2) for proper pressure holding capacity.
If replacement of cap is required, use a proper cap
for this vehicle.
NOTE
After installing radiator cap to radiator, make
sure that the ear of cap lines is parallel to
radiator.

Cooling system and radiator cap holding
pressure (for inspection)
110 kPa (1.1 kg/cm2, 15.6 psi)
5) Tighten hose clamps and inspect all hoses. Replace hoses whenever cracked, swollen or otherwise
deteriorated.
6) Clean frontal area of radiator core.
Cooling System DrainingS7RS0B1606004
1) Remove radiator cap.
2) Drain coolant from radiator drain plug (1).
3) After draining coolant, be sure to tighten drain plug (1) securely.

Cooling System Flush and RefillS7RS0B1606005
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if cap is
taken off too soon.

NOTE
For detail of coolant specification, refer to
“Coolant Description”.

1) Remove radiator cap when engine is cool as follows.a) Turn cap counterclockwise slowly until it reaches a “stop” (Do not press down while turning it).
b) Wait until pressure is relieved (indicated by a hissing sound) then press down on cap and
continue to turn it counterclockwise.
2) With radiator cap removed, run engine until upper radiator hose is hot (this shows that thermostat is
open and coolant is flowing through system).
3) Stop engine and drain coolant from radiator drain plug (1).
4) Close radiator drain plug. Add water until system is filled and run engine until up per radiator hose is hot
again.
5) Repeat Steps 3) and 4) several times until drained liquid is nearly colorless.
6) Close radiator drain plug (1) tightly. 7) Remove reservoir (1) and remove cap (2) from
reservoir (1).
8) Pour out any fluid, scrub and clean inside of reservoir with soap and water.
Flush it well with clean water and drain, Reinstall
reservoir.
9) Fill reservoir with coolant up to “Full” level mark (3).
10) Install reservoir cap (2) on reservoir. 11) Fill radiator with coolant up to bottom of radiator filler neck and install radiator cap, making sure that the
ear of cap lines is parallel to radiator.
12) Run engine at idle speed.
13) Run engine until radiator fan motor is operated.
14) Stop engine and wait until engine comes cooled down to help avoid danger of being burned.
15) Add coolant to radiator up to bottom of radiator filler
neck, and install radiator ca p, making sure that the
ear of cap lines is parallel to radiator.
16) Repeat Step 12) through 15).
17) Confirm that reservoir cool ant level is “Full” level
mark (3). If coolant is insu fficient, repeat Step 9) and
10).
Cooling Water Pipes or Hoses Removal and
Installation
S7RS0B1606006
Removal
1) Drain coolant referring to “Cooling System Draining”.
2) To remove these pipes or hoses, loosen clamp on each hose and pull hose end off.
Installation
Install removed parts in reverse order of removal
procedure, noting the following.
• Tighten each clamp securely referring to “Cooling System Components”.
• Refill cooling system referrin g to Step 7) to 22) of
“Cooling System Flush and Refill”.
