Warning! Follow the appropriate safety precautions when working on the climate control system, see Refrigerant, safety regulations Refrigerant, Safety Regulations.

Note! Read the instructions about slow and large leaks, see Oil in the air conditioning (A/C) system Oil In The Air Conditioning (A/C) System.

Note! Always use new O-rings lubricated with air conditioning (A/C) compressor oil.

Note! Always plug pipes and connectors when working on the climate control system.

Preparations
- Disconnect the battery lead
- Drain the refrigerant from the system, see Draining Draining.

Removal





Remove:
- The clamp holding the battery
- The cable between the drier and the condenser and between the receiver drier and evaporator
- Seal the openings
- The pressure switch connector
- Remove the two mounting nuts from the support
- Remove the drier and the support.

Transfer the support to the new drier
