Will this condenser work with my factory AC lines and fittings?

Yes—this is designed as a direct OEM replacement, so factory line connections mate without adapters. No custom fabrication needed.

Do I need to flush the system before installing a new condenser?

You should flush the system to remove old oil and debris. Use a dedicated AC system flush and follow your vehicle service manual for the correct evacuation and recharge procedure afterward.

Is a new receiver-drier or expansion valve required with this condenser?

Replacing the receiver-drier is good practice when installing a new condenser to remove moisture and contaminants. Your service manual will specify whether a new expansion valve is necessary for your model year.
