Installing
Installing
Installation is carried out in reverse order, noting the following:
–  To fit the heating, the help of a second mechanic is required.
  Note!
t  Check all seals at heater for damage prior to installation and replace damaged seals.
t  Check attachment of coolant pipes to heat exchanger.
   
–  Fit the seal -A- (from the passenger compartment) in the transverse panel -B-, ensuring to correctly position the seal -A-.
–  Seek the help of another person to fit the heating.

–  Guide the bracket for the coolant hoses to the heat exchanger -A- when fitting the heating (from the engine compartment) through the openings of the grommet -B-.
  Note!
t  On fitting the heater, pay attention to both coolant pipes to heat exchanger to ensure that they do not catch on the opening to the plenum chamber or on the sound proofing mat and are bent or damaged.
t  Pay attention to wiring harness. Pulling too firmly could damage individual wires.
–  Re-install components removed with the exception of the driver sides lower trim in reverse order.
  Note!
t  When installing the instrument panel, make sure the intermediate deicer element is properly positioned on heater and that deicer nozzle does not squash intermediate piece.
t  After installing instrument panel, check exit direction and distribution of air flow from deicer vent to windscreen.

–  Check the correct positioning of the grommet -B- in the transverse panel.
–  Seal the brackets for the coolant hoses to the heat exchanger -A- in the openings of the grommet -B-, for example using silicon sealing paste (so that it is water tight).
–  Refit the lower lining on the driver side as well as any other components that were removed.
–  Check the operation of the heating.
–  Check the direction of the air diffusion, depending on the control position (one rotation of the heating control rotates the flexible axle twice by the transmission gear) → Chapter.
