Procedure

NOTE:

With lock carrier installed, engine is removed downward with transmission and subframe.

During installation, all cable ties must be re-installed at the same location.

Collect escaping coolant in a clean container for disposal or reuse.

WARNING:

Risk of vehicle tipping over with engine removed.

Secure vehicle. Luggage compartment must be empty for this.

There is a risk of injury because the fuel is under very high pressure.

Before opening high pressure area of the fuel injection system, fuel pressure must be relieved to residual pressure.

-- Reduce fuel pressure in high pressure area. Refer to Before Opening High Pressure Fuel Injection System .

NOTE:

So that the front wheels can still be turned with the battery disconnected, the battery must only be disconnected with ignition key inserted.

CAUTION:

Risk of destroying electrical components when battery is disconnected.

Observe measures when disconnecting battery.

-- Turn off ignition and remove ignition key.

-- Disconnect the Ground (GND) cable -arrow- from the battery terminal. Refer to BATTERY, DISCONNECTING AND CONNECTING .

WARNING:

Risk of scalding due to hot steam and hot coolant.

When the engine is warm the cooling system is under pressure.
Reduce pressure by covering coolant reservoir cap with a cloth and carefully opening.

-- Open coolant reservoir cap.

CAUTION:

Risk of destroying due to reversed running direction on a used ribbed belt.

Before removing the ribbed belt, marking running direction with chalk or felt-tip pen for reinstallation later.

-- Pivot the tensioner clockwise -arrow- to release the tension on the ribbed belt.
