Do I need to flush the cooling system before installation?

Yes — drain the old coolant completely and flush the system with distilled water before dropping in the new radiator. This removes sediment and old debris that could clog the new core.

Are the transmission cooler lines already connected, or do I need to plumb them myself?

The cooler lines come pre-attached to the radiator. Connect them directly to your transmission cooler ports using the factory hose routing — no custom fabrication needed.

What hose sizes and clamps will I need?

Use OEM-style radiator hoses and clamps that match your original setup. Compare your old radiator inlet/outlet diameters to confirm fitment before ordering hoses separately.
