Will this mount directly using factory attachment points?

Yes. This radiator uses your vehicle's original mounting locations — no drilling or custom brackets needed. Bolt it in place the same way the OEM unit came out.

Do I need to flush the cooling system before installation?

Flush your existing coolant and hoses before mounting the new radiator. Old coolant can degrade performance and reduce the life of the new core.

What's the return window if the radiator doesn't fit?

Test-fit the radiator in your engine bay before final torquing. Once installed and pressurized, it's a permanent part of your system — verify all hose connections and mounting tabs align before tightening everything down.
