Will this bolt straight in, or do I need adapters?

Direct replacement using factory mounting points and OEM hose connections. No adapters or modifications needed—swap the old core out and bolt the new one in place.

Does this come with hoses and clamps?

Radiator assembly only. Reuse your existing hoses and clamps unless they're cracked or hardened, then source replacements separately.

Which engine size do I actually need — 2.0 or 2.5?

This single radiator works with both. The core supports both displacement engines, so one part covers both platforms.
