Will this fit without removing the radiator?

Removal of the radiator is typically required for proper access and installation. Check your service manual for the exact procedure — it's standard work on this generation.

Do I need to flush or refill the refrigerant system?

Yes. Whenever you replace a condenser, the system must be evacuated and recharged by a certified tech with the proper equipment. This is not a DIY job — take it to an AC shop.

What should I inspect while the condenser is out?

Check the compressor, receiver-drier, and all hose connections for leaks or wear. If the old condenser failed, debris may be in the lines — have a pro flush the system before installing this unit.
