Heat Exchanger, R.H.D

Heat exchanger

Note! The illustrations in this service information are used for different model years and/or models. Some variation may occur. However, the essential information in the illustrations is always correct.

Preparatory work




Draining coolant and removing the engine splash guard.

Remove:
- the cover for the expansion tank and raise the vehicle
- the engine splash guard.
Attach a hose on the nipple at the radiator and lower the hose to a container.
Open the nipple and drain off the coolant.




Lower the vehicle.
Detach the radiator hoses from the engine compartment.
Turn the radiator hose connection counter-clockwise to the end position and then pull off the radiator hose.

Removal

Remove:
- the tunnel compartment. See: Floor console Floor Console
- the soundproofing panel on the driver's side. See: Instrument panel lower Instrument Panel Lower.





Note! The heat exchanger has pipes that are factory integrated. These pipes must be cut in order to remove the unit. The heat exchanger in the service kit has separate pipes, however.

Place some paper below the pipe couplings to collect any spilled coolant.
Cut or saw off the pipes.

Applies to vehicles with manual transmission
Remove the clutch pedal. Refer to: Clutch pedal, MMT6, R.H.D, M66, R.H.D, M56, R.H.D Clutch Pedal

Applies to all vehicles.




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

Hint: To facilitate, also route the pipes from the engine compartment.

Remove:
- the 2 x screws and the lead-in's right half, see image
- the section that holds the heat exchanger and evaporator pipes apart.
Pull the heat exchanger pipes through the seal.

Seal the pipes to the heat exchanger so that the remaining coolant cannot run out.





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




Angle the heat exchanger up at the rear edge. Lift out the heat exchanger towards the driver's side.

Installation

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

Install the heat exchanger and heat exchanger pipes through the seal.
The heat exchanger in the service kit has separate pipes.

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.




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

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





Install:
- the 8 x screws for the cover. Tighten
- the air duct
- the brackets on both sides of the climate control unit and the screws, 3 per bracket. Tighten

Applies to vehicles with manual transmission
Install the clutch pedal. Refer to: Clutch pedal, MMT6, R.H.D, M66, R.H.D, M56, R.H.D Clutch Pedal

Applies to all vehicles.
Install the center console. See: Floor console Floor Console.

Finishing

Checking the function and leak tracing
Install the radiator hoses in the connections by the firewall.
Tighten the drain nipple on the radiator.
Fill with coolant and warm up the engine until the thermostat opens. Top up if necessary.
Check that the pipe coupling does not leak.
Install the soundproofing panel on the driver's side in accordance with: Instrument panel lower Instrument Panel Lower.
