Engine Cooling System

General Description

Cooling System Description

S5JB0B1601001

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

S5JB0B1601002

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.

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 been 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 deminelized

water or distilled water.
