Will this work with my aftermarket radiator or does it need the OE unit?

This fan mounts at factory radiator points, so fitment depends on your radiator's core thickness and tank height. If you've kept the OE radiator or installed an equivalent-sized unit, you're good. Swap to an oversized radiator and you'll want to verify clearance before final installation.

Do I need any wiring adapters or does it plug straight in?

Connector type and wiring requirements are not confirmed in the product specs. Have your factory wiring harness ready and test-fit the connector before removing the old fan — mismatched plugs mean a trip back or an adapter hunt.

What's your return window if the fan doesn't spin or is DOA?

Return policy details aren't included with this listing. Contact ModSupply directly with your order number — they'll walk you through inspection and replacement options if you get a bad unit.
