Do I need any hoses or clamps to install this?

Your existing hoses will reconnect to the new radiator—most buyers reuse them. Check condition before install; if they're cracked or soft, replace them at the same time. Clamps typically transfer over from the old unit.

Will this fit if I have the manual transmission version?

Yes. This radiator is engineered to work with both automatic and manual transmissions in this model year range, so transmission type doesn't affect fitment.

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

Radiators are subject to standard modsupply.com return policy—confirm your specific year and engine size before purchase to avoid fitment issues, since core design varies by powertrain.
