Will this bolt directly into my car without modifications?

Yes. This radiator uses factory mounting points — no drilling, no bracket fabrication. Install the same way the original came out.

Do I need to flush the cooling system before installation?

Recommended. Drain old coolant, rinse the block and hoses if the system has been sitting, then fill fresh. Clean coolant prolongs radiator life.

Are hose clamps and coolant included?

Radiator assembly only. You'll reuse your existing hoses and clamps if they're in good shape — inspect them first. Coolant is sold separately.
