Do I need to drain the coolant system before installation?

Yes. You'll need to drain the existing coolant, disconnect hoses, and remove the mounting bolts. Refer to your vehicle's service manual for the correct drain procedure and refill capacity.

Will this work if I have a manual transmission instead of automatic?

This radiator is designed for both. A single OEM unit handles cooling for manual and automatic Sportages from this generation—no separate part needed.

What should I do about hoses and clamps?

Inspect existing hoses for cracks or soft spots while you have the radiator out. If they're original or more than five years old, replacement hoses and fresh clamps are a smart move. They're inexpensive insurance against leaks after you button everything back up.
