Will this work if I have a manual transmission instead of automatic?

Yes. This radiator is built to cool both transmission types — the cooling circuit is the same across auto and manual models for this generation Rogue. No modifications needed.

Do I need a new thermostat or water pump when I install this?

Not required. This is a radiator-only replacement. If your thermostat or pump are worn, address those separately — but this radiator will bolt in without them.

Will I need new hoses or clamps?

Factory hose connections are standard Nissan sizes. Reuse your existing hoses and clamps if they're in good condition. If they're cracked or brittle, swap them out before installation.
