Skoda Workshop Service and Repair Manuals

Removing and installing air conditioning unit (Climatic and Climatronic) Special tools and workshop equipment required t  Hose clamp -MP7-602 (3094)- t  Hose clamp -T30096 (3093)- t  Pneumatic gun, commercially available Removing and installing   Note t  Repairs must only be carried out in specialist service centres which have suitably trained personnel and are fitted out for working on the refrigerant circuit. t  A second mechanic is required occasionally for removing and installing the air conditioning unit. t  On certain engines remove the engine cover, the intake hose to the exhaust turbocharger, the DPF cover and if necessary the intake hose to the air filter for an easier access to the expansion valve → Engine, corresponding repair group. –  Drain the refrigerant circuit with the aid of the A/C service station. –  Remove the dash panel → Body Work → Rep. gr.70. –  Remove rear ducts of footwell on the right and left → Chapter.   DANGER! The coolant temperature can be over 100 °C when the engine is warm. The cooling system is under pressure - risk of scalding! Before repairs, reduce pressure and temperature if necessary.

–  Pinch off coolant hose -1- with the hose clamp -MP7-602 (3094)-. –  Pinch off coolant hoses -2- and -3- with hose clamp -T30096 (3093)-.   Note If the heat exchanger is replaced, the coolant must be replaced. In this case let the coolant drain → Engine → Rep. gr.19, without pinching off the coolant hoses. –  Separate the quick couplings at the heat exchanger. –  Vehicles with cover plate in front of the expansion valve - remove cover plate for expansion valve → Chapter.

–  Place the hose -1- a little onto the upper connection. –  Hold a container -2- below the lower connection -3-. –  Carefuly blow with a pneumatic gun the remaining coolant out of the heat exchanger into the container -2-.

–  Release screws -1- of refrigerant lines -2-. –  Remove the refrigerant lines from the expansion valve -3-. –  Cover the floor covering in the vehicle interior with a liquid impermeable foil and absorbant paper.

q	Installing:

Installation is performed in the reverse order, pay attention to the following points:

–	First of all install the seal to the bulkhead from the passenger compartment and then guide the heat exchanger flange and the refrigerant connection through the seal → Fig..

–	Pay attention to the fitting position of the seal → Fig..

–	Attach the refrigerant lines to the expansion valve → Chapter.

–	Top up coolant → Engine → Rep. gr.19.

–	Fill the refrigerant circuit with the aid of the A/C service station.
