Do I need to flush the cooling system before installation?

Yes. Drain and flush the existing coolant completely, then refill with fresh coolant and distilled water per your service manual. Old coolant can cause corrosion in a new radiator.

Will this radiator work if I've upgraded to a turbo engine later?

No. This radiator is sized for the naturally aspirated 2.5L only. A turbo conversion requires a heavy-duty or larger-capacity radiator to handle increased heat output.

What hose connections does this radiator use?

Factory inlet and outlet sizes—your existing upper and lower hoses will connect directly. Verify hose condition before install; cracked or deteriorated hoses should be replaced at the same time.
