Factory Lumina radiator engineered for 3.1L, 3.4L, and 3.8L engines — direct replacement with proven cooling capacity. Built to OEM specification, this core handles daily driving and moderate performance without compromise. Drop-in fitment means no modification or fabrication required.
Will this radiator work with my existing hoses and fittings?
Yes — OEM design means your current upper and lower hoses connect without modification. Check hose condition before install; if they're original from the mid-90s, replacing them at the same time is smart preventive maintenance.
Do I need to flush the cooling system before installing this?
Flush the system thoroughly to clear old coolant and sediment. Clean passages give your new radiator the best chance to cool efficiently and extend its life.
What if the radiator leaks within the first few weeks?
Each radiator passes in-house quality inspection before shipping. If you experience a defect, contact support with photos and order details for resolution options.
