Will this bolt directly into my truck without modifications?

Yes. This radiator uses factory mounting points and tank connections — no drilling, welding, or bracket fabrication needed. Install it the same way the original came out.

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

Flush your system and refill with fresh coolant. Old coolant can damage the new core and shorten radiator life, especially on high-mileage trucks that see heavy use.

What if the radiator leaks after I install it?

Contact ModSupply support with photos of the leak and your order number. We'll walk you through warranty coverage based on your purchase date and installation method.
