Will I need new hoses and clamps when I install this?

Your existing hoses will fit—this is a direct OEM replacement. Inspect your current upper and lower hoses before installation; if they're brittle or cracked, replace them at the same time to avoid future leaks.

Does this radiator come with a new cap and overflow tank?

The radiator assembly is the core and tank only. You'll reuse your existing radiator cap and overflow bottle from your Odyssey—they're not included here.

Can I reuse my old transmission cooler lines if they fit?

Yes, if your lines connect to the same ports as the original radiator, they'll work with this unit. Check that fittings align before final assembly to avoid cross-threading.
