CSF 10-12 Ford Flex 3.5L OEM Plastic Radiator

This is the CSF 3511 radiator, a direct replacement for your 2010-2012 Ford Flex with the 3.5L engine. It's built to match the original equipment specifications, meaning it will fit right in and perform as expected to keep your engine cool.

CSF uses a plastic tank construction for this radiator, similar to the factory unit. This design helps keep the weight down and is a common approach for many modern vehicles. The core is designed for efficient heat transfer, which is crucial for preventing your engine from overheating, especially during demanding driving conditions or in hot weather.

When you're replacing your radiator, it's a good idea to also consider replacing your coolant and checking your hoses. This CSF radiator is a solid option if you're looking to get your Flex cooling system back to proper working order.
