Do I need new hoses or clamps when I install this?

Your existing hoses and clamps will reuse — this is a direct swap. Inspect them during install for cracks or hardening; if they look compromised, replace them while you're in there.

Will this work with my manual transmission Civic?

This radiator is engineered specifically for automatic models. Manual transmission Civics use a different cooler routing and core capacity — confirm your transmission type before ordering.

What do I need to flush or refill after installation?

You'll need fresh coolant to refill the system after swap-out. Use Honda-spec coolant or equivalent; refer to your owner's manual for capacity and mixture ratio. Bleed the system to remove air pockets.
