Do I need to drain the cooling system before installation?

Yes. Your vehicle's cooling system must be completely drained and flushed before radiator removal and replacement. Refer to your owner's manual or service guide for proper drain procedures and refill capacity.

What coolant should I use after installation?

Use Toyota/Lexus factory long-life coolant as specified in your owner's manual. Using the correct coolant type is critical for corrosion protection and thermal performance.

Does this come with hoses and clamps?

This is the radiator core assembly only. You'll need to reuse your existing hoses and clamps if they're in good condition, or source replacements if any are damaged during removal.
