Installation instructions - Audi A8 PU from 2014 ▶
Edition 09.2013
The cooling system does not need to be upgraded if it is possi-
ble to guarantee that the engine is only exposed to moderate
stress, e.g.:
◆ The permissible gross combination weight is significantly un-
derrun
◆ No high ambient temperatures
◆ No long, steep inclines
◆ No high altitude journeys
In any case, the coolant temperature display must be carefully
monitored. If the needle in the display moves into the hot area,
the speed must be reduced immediately. A cool-down time must
also be allowed for if necessary. This involves the allowing the
engine to idle for approx. 2 minutes to prevent a build-up of
heat.
Note
◆ In vehicles with air-conditioning, the engine cooling system
can be relieved by switching off the air-conditioning. This al-
so improves the vehicle's start-up behaviour and makes it
safer to overtake.
◆ If, in exceptional cases, the cooling system does not need to
be upgraded, the seller must advise the buyer accordingly if
the vehicle is sold.
