Will this bolt directly into my Compass without modifications?

Yes. This radiator mounts at factory attachment points — no drilling, brackets, or adapters needed. Standard bolt-in replacement.

Do I need to flush the system before installing this radiator?

Yes. Drain and flush your cooling system completely before install to remove old coolant and debris. Use fresh coolant per your vehicle's spec when refilling.

Are hose clamps and coolant hoses included?

The radiator assembly ships without clamps or hoses. Reuse your existing hoses if they're in good condition, or source replacements separately to ensure proper OEM sizing.
