• Compatible models: Subaru Impreza (2012–2016 H4 2.0L), Crosstrek (2013–2017 variants), Forester (2014–2018)
• Cross-reference numbers include CO29103C, 58492, 7512979 and OEM codes such as 73111FJ000/73111FJ040
• Compare your under-hood decal or service manual for refrigerant and oil specifications before installation

What performance and durability features does this compressor offer?

The compressor is designed to deliver stable pressure, low vibration and reduced noise compared with damaged or failing compressors. Its internal components and pulley system are balanced for smooth operation so the cabin cooling feels consistent.

• Engineered for sufficient operating pressure to restore cooling capacity
• Balanced design minimizes vibration and operating noise
• Complete assembly reduces need to transfer parts from old unit

What should I check before and after installing the compressor?

Replacing a compressor is often paired with inspection and maintenance of the whole A/C circuit. Dirty condensers or a faulty cooling fan can raise system temperatures and increase pressure, which may have caused the original failure.

• Inspect and clean or replace condenser and cooling fan if clogged or damaged
• Verify total refrigerant and oil charge using the vehicle’s under-hood decal or service manual
• Evacuate and vacuum the system, then recharge to correct specification to avoid premature wear

Can I install this myself or should a professional do it?

Installation can be performed by a competent DIYer with the right tools, but proper refrigerant handling and evacuation require certified equipment and knowledge. If you’re not comfortable with A/C recovery, vacuum and recharge procedures, seek a professional technician to ensure safety and compliance.

• DIY installable for experienced users with A/C tools and service knowledge
• Professional service recommended for refrigerant recovery and system recharge
• Follow torque specs and replace any worn seals or O-rings to prevent leaks
