Vehicle without Particulate Filter:
-- Remove the connectors from bracket and disconnect:
- For the Oxygen Sensor 1 after Catalytic Converter -GX7-
- For the Oxygen Sensor 1 before Catalytic Converter -GX10-
-- Free up the wires to the heated oxygen sensors.
Continuation for All Vehicles:
- Use the Pry Lever :80-200 for removing the spiral clips in the following steps.
Risk of destroying due to electrostatic discharge.
- Do not touch the connector terminals by hand.

TIP:
The rear bolt in the cylinder block is accessible from the wheel housing side. To do so, loosen the wheel housing liner area and push it aside. Refer to OVERVIEW - FRONT WHEEL HOUSING LINER .
-- Remove the bolts -arrows- for the transmission mount -1-.
Risk of damaging the lines and hoses, as well as the engine compartment by lowering the engine/transmission assembly.
- Make sure all connections between the engine, transmission, subframe and body have been disconnected.
- Carefully lower and guide the engine/transmission assembly out of the engine compartment.
- Make certain that there is enough clearance for the A/C compressor.
- Pay attention to the heat shield for the center tunnel.
-- Move the transmission side of the engine/transmission assembly forward and then lower it.
