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.
