Do I need a new receiver-drier or expansion valve when I install this?

Condenser replacement alone doesn't require swapping those components. However, if your system has been open for extended time or you're recovering old refrigerant, follow your service manual's guidance on drier replacement for best results.

Does this come with O-rings or seals?

The assembly includes the condenser with factory ports—any O-rings or seals at connection points come pressed in. Bring your own hose seals and refrigerant oil if you're doing a full system service.

What's the return window if it doesn't fit?

Test-fit the mounting tabs and connection points against your vehicle before finalizing installation. Once refrigerant is charged or hoses are permanently soldered, the core is not returnable—verify fitment first.
