Will this radiator work if I switch from automatic to manual transmission later?

This unit is engineered for both. You're covered either way without needing a different radiator down the road.

Do I need to flush the cooling system before installing the new radiator?

Flushing out old coolant and sediment before swapping in a fresh radiator is smart practice—it ensures your new unit runs clean and extends its lifespan. Check your service manual for flush procedure specifics.

What comes with the radiator—hoses, clamps, or mounting hardware?

The radiator assembly ships solo. You'll reuse your existing hoses, clamps, and mounting brackets from the old unit unless they show wear.
