Cooling System Description
The cooling system consists of a degassing tank, a
radiator, radiator cooling fan, hoses, pipes, a water
pump, an additional heater, a turbocharger electric water
pump and a thermostat assembly.
Coolant Description
WARNING
!
• Do not remove degassing tank cap to
check engine coolant level; check coolant
visually at the see-through degassing tank.
Coolant should be added only to
degassing tank 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
and degassing tank without causing the
solution to boil. Removal of the degassing
tank 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.
Engine Cooling System: For Diesel Engine Model 1F-14
General Description
The coolant recovery system is standard. The coolant in
S6JB0A1621001
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 been filled with a quality coolant
that is a 50/50 mixture of water and ethylene glycol
antifreeze.
S6JB0A1621002
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 deminelized
water or distilled water.
