Do I need to drain my coolant system before swapping this in?

Yes. Drain your existing coolant completely before removing the old radiator. Once the new unit is mounted and all hoses are reconnected, refill with fresh coolant and bleed air from the system per your owner's manual.

Will this radiator work with my transmission cooler lines if I have an automatic?

This radiator is built for both manual and automatic models. If your van uses transmission cooler lines integrated into the radiator, they're included in this assembly—no separate brackets or adapters needed.

What hoses do I need to order separately?

Hose compatibility depends on your specific cooling setup. Check your service manual or the old radiator hose diameters before ordering—this radiator assembly connects with factory hose points, but the hoses themselves are your responsibility if replacement is needed.
