Will I need new refrigerant or oil when I swap this in?

Refer to your vehicle's service manual for refrigerant type and capacity. The system will need to be evacuated and recharged by someone with proper AC recovery equipment — don't skip this step or you'll lose cooling and damage the compressor.

Do the rubber seals and hose connections come with this unit?

The condenser ships as an assembly. Test-fit the connection points to your existing lines before final installation — sealing method depends on your system's original design and whether you're reusing existing hoses.

Can I install this myself, or do I need to go to a shop?

Removal and install are straightforward hand-tool work if you're comfortable under the hood. The real work is the AC system evacuation and recharge — that requires a certified tech with recovery equipment. Most shops handle the whole job end-to-end and guarantee the cooling performance afterward.
