Will this bolt directly to my truck without modifications?

Yes. This radiator mounts at factory points with no drilling or fabrication required. Bolt-in installation using existing hardware holes.

What prep or flushing is needed before installation?

Flush your coolant system thoroughly before swapping in a new radiator. Old coolant can carry debris that damages the new core. Use distilled water and a system flush product if your lines haven't been serviced recently.

Do I need new hoses or clamps when I install this?

Hoses and clamps are not included. Inspect your existing upper and lower hoses for cracks or soft spots — if they're original or over five years old, replace them while you have the radiator out. New clamps cost little and prevent leaks.
