Removing engine

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2016 Porsche Panamera, 2015 Porsche Panamera, 2014 Porsche Panamera, 2013 Porsche Panamera, and 2012 Porsche Panamera. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Caustic fluids
  • Danger of chemical burns

→ Avoid contact with caustic fluid.

→ Wear personal protective gear.

→ Ensure that there is good ventilation.

→ If you do come into contact, wash off immediately with plenty of warm water and contact a doctor if necessary.

CAUTION: Hot components
  • Risk of burns

→ Let hot components cool down.

→ Wear personal protective gear.

IMPORTANT: For installation, it is a good idea to mark the installation position of the front-axle carrier diagonally at at least two places on the body. To do this, place the marks vertically with respect to the floor of the body using a felt-tip pen (e.g. mark along the front-axle carrier mount with the pen). This makes it easier to correctly position the front-axle carrier on the body during re-installation.
IMPORTANT: When lowering the engine, make sure that cables, hoses or lines are not trapped accidentally between the engine and body. To prevent this, a second person must make sure that the cables, hoses and lines do not get caught.
IMPORTANT: The pictures shown in this document may differ from the original.
