Does this come with hoses and clamps?

The radiator assembly ships alone. You'll reuse your existing hose kit and clamps during installation—no additional hardware needed unless yours are cracked or deteriorated.

Will this radiator work if I've already upgraded my engine displacement?

This core is rated for 2.4L through 4.2L. If your displacement falls within that range, you're covered. Beyond 4.2L, cooling capacity may not keep pace—verify your engine specs against the rating before ordering.

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

Yes. Drain the old coolant, flush the block and lines with distilled water, then refill with fresh coolant. Old sediment or rust particles will clog the new 3-row core quickly and defeat the upgrade.
