Will this radiator work with my 2015 Sonata if it has the turbo engine instead of the 2.4L?

No—this is engineered specifically for the naturally aspirated 2.4L. Turbo models use a different cooling system. Verify your engine displacement before ordering.

Do I need to drain and refill coolant myself, or does this come pre-filled?

It ships dry. You'll need to drain the old system, flush the block and hoses if needed, then refill with fresh coolant per your owner's manual specs.

What if the radiator arrives damaged or fails shortly after install?

Contact ModSupply with photos and your order number. We'll evaluate the issue and handle a replacement or return based on what we find.
