Will this bolt up using my truck's existing radiator shroud mounting points?

Yes. This assembly mounts directly at the factory points — no drilling, welding, or bracket fabrication needed. Line up and bolt down.

Do I need to drain the radiator to install this?

Installation method specifics aren't detailed in the product data. Before you begin, consult your service manual to confirm whether coolant drain-down is necessary for your model year.

What if the fan arrives damaged or doesn't spin freely?

Inspect it immediately upon arrival. Test the blade by hand — it should rotate smoothly without resistance or grinding. Contact ModSupply support right away if you find defects; return process varies by order date and condition.
