Will this bolt directly into my vehicle without modifications?

Yes — this is a factory OEM radiator with original mounting geometry. Installation uses the existing factory mounting points with no drilling or fabrication needed.

What about the hoses and connections — do I reuse my old ones?

You can reuse your existing hoses if they're in good condition. The factory tank connections are original spec, so old hoses will fit. If hoses show cracks or leaks, replace them during install to avoid future failures.

Is flushing the cooling system necessary before I install this?

Flushing is not required to install the radiator, but running old coolant through a new core will compromise performance and longevity. Flush the system before filling with fresh coolant for best results.
