Install a hose on the nipple at the radiator.
Feed the hose down to a container.
Open the nipple. Drain off the engine coolant.

Removal

Remove:
- the tunnel compartment. See: Floor console Floor Console
- the glove compartment. See Glove compartment Glove Compartment.
Detach the central electrical unit from its bracket but allow it to hang from the wiring. See: Control module relay box passenger compartment Control Module Relay Box Passenger Compartment.





Remove:
- the brackets on both sides of the climate control unit and the screws, 3 per bracket
- the 8 x screws for the cover.
Pull the cover at angle downwards/backwards. See illustration.




Place some paper below the pipe couplings to collect any spilled coolant.
Remove the clips holding the pipes. See the illustration.

Note! Note how the clips are installed.


Press the pipes towards the cowl panel so that they protrude into the engine compartment.

Hint: Also pull the pipes in from the engine compartment. This will make it easier.

Plug the pipes for the heat exchanger so that the coolant cannot run out.
Angle the heat exchanger up at the rear edge and lift out towards the passenger side.

Note! Note how the seal is located on the heat exchanger.

Installation

Note! Install a new seal carefully using the removed evaporator as a template.

Install the heat exchanger.

Hint: To facilitate assembling the pipes, lubricate the ends with a little oil.

Note! Use new O-rings for the pipe ends.

Install the pipes at the connection to the heat exchanger pipes.





Note! Use the new clips when installing the pipes.

Install the clips so that they lock securely. A click must be heard.

Note! The clips only fit one way in the pipe connection.

Finishing

Checking the function and leak tracing
Tighten the drain nipple on the radiator.
