Install the coolant expansion tank for the low-temperature coolant circuit (charge air cooler)

CAUTION: Materials harmful to health. 
Contact with fluids harmful to health! 

• Note and follow safety instructions on containers.
• Conduct all work in appropriate personal protective equipment only.

NOTE: TECHNICAL INFORMATION 
Immobilization period-long fill of coolant! 
Do not reuse used coolant.
When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be emptied and refilled.
In the case of other removal work involving the draining of part quantities of coolant, the coolant level must be topped up with new coolant.

NOTE: TECHNICAL INFORMATION 
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
