Buick Regal AC Compressors: Check Year, Engine and Part Reference

This guide summarizes seller titles reviewed on 2026-10-18, from a catalogue snapshot dated 2026-09-19. It is historical buying evidence, not current stock or verified compatibility. Confirm the exact application, current price and availability with the seller.

Match the application before comparing prices

The supplied US title review contained older Regal compressor descriptions around 1996–2004/2005 and newer descriptions around 2011–2017. Sellers mentioned different engines and references. Do not assume two compressors interchange because both titles mention Regal.

The newer descriptions included 2.0L and 2.4L. The draft recorded one RYC listing labelled FG565 for 2011 and another labelled IG244 for a 2012 2.0L application. Those are seller-described references, not an independently verified parts catalogue.

Check the component and the package

The reviewed results also included a belt tensioner and a compressor naming other vehicles without Regal. Check that the listing is the component you intend to buy.

Some sellers named five-groove or six-groove pulleys. Ask the supplier to confirm the required specification against the old unit and vehicle details. Do not choose by a photograph alone.

The review recorded KT222 as a compressor kit and KTC222 as a compressor-and-condenser kit. Contents vary by listing. Read exactly what is supplied, whether the unit is new, used or remanufactured, and the seller's warranty and returns terms.

Before ordering

Have a qualified repairer diagnose the fault and identify the required compressor. A warm vent or noise alone does not identify a failed compressor. Ask the repairer about the correct refrigerant and replacement procedure; this guide provides no repair instructions.

FAQ

Will an older Regal compressor fit a newer Regal?

The title review does not establish that. Verify the exact part reference, year, engine and relevant specifications with a parts supplier.

Is a 2011 2.0L compressor the same as a 2012 2.0L unit?

The reviewed sellers used different references. Do not assume interchangeability; have the supplier check the exact application.

Should I buy a compressor kit?

Compare the written contents with what the repairer specifies. A kit name does not establish what your repair requires.
