Will this bolt straight to my truck without adapters?

Yes. This mounts at factory points — no drilling, fabrication, or adapter brackets needed. Bolt it in place and connect your existing hoses to the driver-side outlet.

Do I need to flush my cooling system before installing this?

Flushing beforehand is smart practice. Old coolant can clog a new radiator. Run fresh coolant through your entire system after installation to avoid premature blockage.

What if the outlet size doesn't match my hoses?

Verify your hose diameter against the driver-side outlet opening before ordering. If you need an adapter or step-down fitting, those are available separately — confirm the connection size with your service manual or current hose specs.
