WARNING: This page is about a different car, the 2015 Audi Q7, 2014 Audi Q7, and 2013 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:

Risk of scalding due to hot steam and hot coolant.

  • The coolant system is under pressure when the engine is warm.
  • Cover the coolant reservoir cap with a cloth and then open it slowly to release the pressure.
NOTE:

Arrows on coolant pipes and coolant hoses must line up across from each other.
