Will this bolt straight into my car without modifications?

Yes. This mounts at factory radiator support points with no drilling, cutting, or adapter work. Use your existing hose clamps and hose connections.

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

Flushing before install is smart practice. Old coolant can carry debris into a fresh radiator. Run a system flush, rinse with distilled water, then fill with fresh coolant after you bolt this in.

What condition is this radiator in?

Check the product listing for condition details — OEM radiators ship either new or remanufactured depending on inventory. Confirm the exact condition before checkout.
