Will this bolt directly into my truck without any modifications?

Yes. This radiator mounts at the factory points — no drilling, fabrication, or adapter brackets needed. Bolt it in and reconnect your hoses.

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

Flushing your system before installation is smart practice to remove debris and old coolant that could clog a new radiator. Use a coolant flush kit and rinse thoroughly with distilled water.

Are the hose connections the same size as my original radiator?

This radiator is built to OEM specifications, so connection points match the factory original. Verify your existing hoses fit snugly — if they're cracked or brittle, replace them while you're doing the swap.
