Will this bolt directly into my cooling system without modifications?

Yes. This radiator uses factory mounting points and connects to OEM hose locations. No adapters, brackets, or modifications needed.

Does this come with a thermostat, hoses, or clamps?

The radiator assembly is included. Verify your existing hoses and clamps for reuse before installation — replacement of those components depends on their condition.

Can I flush and reuse my existing coolant, or should I start fresh?

You can flush the system and reuse compatible coolant if it's still clean. If your coolant is discolored or hasn't been changed in over two years, this is a good time to replace it with fresh OEM-spec fluid.
