Do I need to drain the entire cooling system before swapping this in?

Yes. Disconnect the lower radiator hose, drain into a pan, then remove the upper hose and mounting bolts. Have a catch container ready—coolant spills fast. Refer to your vehicle's service manual for specific drain procedures and refill capacity.

Will this bolt straight to my engine bay without any adapter brackets?

This radiator mounts at factory points—no brackets or modifications needed. Bolt holes align with your original mounting locations.

Can I reuse my old hoses, or do they need replacement?

Inspect both radiator hoses for cracks, splits, or soft spots before reinstalling. If they're original equipment and over five years old, replacing them now prevents a cooling failure down the road. New hoses aren't included—source them separately if needed.
