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

Yes. Flush the system thoroughly to remove sediment and old coolant before hanging the new radiator. Debris in the old lines will compromise the new core right away.

Will this radiator work with my factory hose connections?

This radiator is built to OEM spec, so your factory hoses and clamps will bolt straight on. No adapter fittings needed.

What about the transmission cooler and heater hose ports?

This assembly includes all factory ports and fittings for transmission oil cooler and heater circuits. Connect exactly as your original radiator was plumbed.
