Will this radiator work with the stock cooling fan and shroud?

This is an OEM replacement radiator with factory mounting points. Your existing fan and shroud are designed for it — no adapter or modification needed. Bolt it in and you're done.

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

Yes. Drain the old coolant completely and flush the system to remove debris before installing the new radiator. Any contaminants left behind can compromise cooling performance and flow rate.

Does this come with new hose clamps or connection fittings?

The radiator assembly ships with the core and tank. Hose clamps and fittings are not included — reuse your existing ones if they're in good shape, or pick up new clamps separately to be safe.
