Will this radiator fit without modification to my cooling system hoses?

Factory mounting and connection points are preserved. Existing hose routing should work without modification, but test-fit before final installation to confirm alignment with your specific vehicle configuration.

What condition is this radiator in, and does it come with any internal flush or prep?

This is a complete assembled unit ready for installation. Flush your cooling system before install to remove any debris from the old radiator, then fill with the coolant type specified in your vehicle manual.

Do I need to drain and refill coolant myself, or should I have a shop handle installation?

Radiator replacement is a straightforward DIY job with basic hand tools if you're comfortable working with coolant and disconnecting hoses. If you're unsure about coolant handling or hose routing, a shop can have this installed in under an hour.
