BDFHYK A/C Compressor 78391

A clutch-equipped compressor supplied with PAG oil is designed to restore air conditioning in specified Toyota Corolla and Matrix models, with O-rings, gaskets, and a connector included. That bundled setup may simplify sourcing the main replacement parts, but it does not make the compressor universal or remove the need for a correct fitment check.

For installation, the listing recommends using a qualified technician. That matters with an A/C system, where choosing a part for the wrong engine or model year can turn a repair into a return or a second visit to the shop.

How to use it

This unit is listed for the Toyota Corolla and Toyota Matrix with a 1.8L L4 engine, covering the stated model years below. Before ordering, compare your vehicle’s year and engine with that application, and match the replacement part number where possible. The listing provides several cross-reference numbers, those can help distinguish this compressor from a similar-looking unit, but they are not a substitute for confirming the exact fit.

The compressor is intended for an R134a system and comes with PAG oil described as pre-charged for initial use. It also includes O-rings, gaskets, and a plug-and-play connector. The supplied details do not explain whether every vehicle-specific installation step or additional part is covered, so plan on having a technician assess the system rather than treating the included pieces as a complete repair kit. A practical example: if a shop has confirmed the compressor is the failed component, these included items may be useful when preparing for the replacement, they do not establish that the rest of the A/C system is ready to go.

Pros

• Includes the clutch with the compressor, rather than offering a clutch-only part.
• Listed for two Toyota models and a specific 1.8L L4 application, which gives buyers a clear starting point for fitment checks.
• Includes O-rings, gaskets, and an R134a connector, the compressor is also described as pre-charged with PAG oil.
• The manufacturer describes high-strength aluminum construction and wear-resistant components. It also claims a 4,500W cooling capacity at 140°F and operation below 70 dB, these are listing claims, not independent test results.

A limitation worth weighing: this is an application-specific repair part, not a general-purpose compressor. If only the clutch needs attention, replacing the compressor assembly may not be the same approach as sourcing a clutch alone. Worth considering if your vehicle matches the listed application and a technician has identified the compressor as the part to replace. It may not suit you if you need a confirmed fit for a different engine, vehicle, or A/C system.

Should you buy it?

This is a sensible candidate when the vehicle, engine, and replacement number line up, and you want a compressor assembly that includes the clutch and basic sealing components. The listing says each unit is tested for cooling performance, noise, durability, and leak resistance, but those statements are not a substitute for a verified fit or a diagnosis. If your application is uncertain, or you are expecting a simple DIY swap, pause: professional installation is strongly recommended, and the supplied information does not establish that the job requires no other system work. On the spec sheet, the included oil and connector are useful details, the decisive question is still whether this exact compressor matches your car.
