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

Yes. Drain the old coolant, rinse the system to remove sediment, then refill with fresh coolant. Clean lines mean better heat transfer and longer radiator life.

Will this work if my car is an automatic transmission model?

This radiator is built specifically for AT models. Manual transmission Miatas use a different radiator design, so confirm your transmission type before ordering.

What hoses and clamps are included?

Radiator assembly only — you'll need to reuse your existing hoses and clamps or source replacements if they're cracked or leaking. Check condition during installation.
