Will this fit the standard gasoline Accord, or is it hybrid-only?

This is engineered specifically for the hybrid model. The cooling system demands differ between the hybrid and gas engines, so use the hybrid radiator for hybrid vehicles only.

Do I need to flush the system before installing this?

Yes. Drain the old coolant and flush the system to remove debris, then refill with fresh hybrid-compatible coolant. Clean passages ensure the new radiator performs at full capacity.

What hardware comes with this—does it include the fan shroud or hoses?

The radiator core assembly ships alone. Reuse your existing mounting brackets, shroud, and hoses unless they're damaged. Test the fan shroud fit before finalizing installation.
