Do I need to flush the cooling system before installing this radiator?

Yes. Drain and flush the existing coolant and hose passages before mounting the new radiator. Old debris will reduce cooling efficiency and void performance claims.

Will this radiator work if I've upgraded to a larger water pump or electric fans?

This radiator is sized for stock cooling systems. If you've upgraded the pump or added electric fans, test-fit and monitor coolant temps during break-in to confirm adequate flow and capacity.

What mounting hardware do I need?

Factory isolation mounts and fasteners are not included with the radiator assembly. Reuse your existing brackets and hardware from the original unit, or source OEM replacements if damaged.
