The RYC Automotive FG275 AC Compressor is a remanufactured air conditioning unit designed to replace failed factory components in specific vehicle models. We selected this unit for our review because it serves as a common aftermarket replacement for a wide range of OEM cross-reference numbers, including 15-21198 and 4719005. This remanufactured compressor is pre-filled with oil and has been tested for durability, noise, and leaks to ensure it meets standard performance expectations upon installation.
The FG275 Compressor features a series of interchange part numbers such as CS10046, CS20028, and 22853678, which define its compatibility. Because a compressor is the heart of the vehicle’s cooling system, verifying the exact displacement and voltage rating is critical; a mismatch in these electrical specs can blow fuses or cause the unit to fail under load. This specific remanufactured unit comes pre-filled with oil, but you must confirm whether your system requires PAG or POE oil and the specific fill amount required before starting the replacement. While the FG275 is a remanufactured unit, it is important to verify if your specific sub-model requires a unique mounting bracket configuration, as even minor variations in engine bay layouts can prevent a standard fit.
What to Check Before Buying the FG275 Compressor
Confirming these technical details before ordering ensures the part functions correctly and avoids the need for secondary hardware purchases.
- Verify if the pulley and clutch plate assembly is included, as some listings provide a bare compressor that requires a separate purchase.
- Check if the internal seals and gaskets are included in the box or if you need to order a separate gasket kit.
- Cross-reference your vehicle’s OEM part number against the FG275 interchange list, including numbers like 15-21583 or 15893101.
- Consult the manufacturer’s support page to confirm the required oil type and volume for your specific vehicle’s cooling system.
Comparing the FG275 Compressor to Other Options
The FG275 Compressor is a remanufactured unit, which functions as a rebuilt mechanical pump that circulates refrigerant to cool your car’s interior. Buyers looking for a remanufactured option typically prioritize a lower price point over a brand-new, original equipment (OE) unit. If you require a compressor from a primary global manufacturer like Denso or Sanden, or if your vehicle requires a specialized high-pressure rating that exceeds standard aftermarket specs, you may want to look at new OE replacements instead. A remanufactured unit like this is ideal for standard replacements where the goal is to restore factory cooling functionality without the cost of a new assembly.
