Do I need new hoses or fittings when I install this?

Your existing lines should reuse—check them for cracks or kinks before reinstalling. If either hose shows wear or damage, replace it at the same time to avoid a slow leak down the road.

Will this condenser work if my old one was leaking?

Yes, but flush the system before you install this one. Any residual moisture or debris from the old condenser can damage the compressor. A flush takes an hour and prevents a $500 problem later.

What do I do after installation to get the AC running again?

You'll need to pull a vacuum on the system for 20–30 minutes, then charge it with the correct refrigerant type and volume for your vehicle. A basic AC vacuum pump and scale are standard tools for this job—your service manual has exact specs.
