Do I need to drain the cooling system before pulling the old radiator?

Yes — drain the system completely into a container. You'll need to disconnect the upper and lower hoses and remove the mounting brackets. Refer to your vehicle's service manual for the exact drain procedure and refill capacity.

Will this radiator work with my current hoses and connections?

This uses factory port sizes and locations, so your existing OEM hoses should mate without issue. Inspect hoses for cracks or soft spots while you have the system apart — if they're original, replacing them now saves a comeback later.

What coolant should I use when I refill?

Check your owner's manual for the correct coolant type — Hyundai and Kia models from this era often specify a specific color and formula. Using the wrong coolant can cause corrosion inside the new core.
