• Downflow radiator design with one-row core
• Transmission oil cooler included; engine oil cooler not included
• Die-cut gasket design for leak resistance
• Individually pressure tested during production
• Factory-style fitment for straightforward replacement
• Core dimensions: 19 15/16 in. height, 27 3/16 in. width, 1-1/4 in. thickness
• 1 3/4 in. inlet and outlet diameters

Detailed Description

This radiator is built to match original equipment dimensions and cooling layout for Ford Expedition and Lincoln Navigator applications. The core uses premium aluminum with cadmium-plated tubes inside and out to help resist premature failure, while the plastic tank design follows the OE-style configuration used on these vehicles. Part Number 2609 also includes a plated transmission oil cooler and is engineered to maintain proper cooling performance in high-mileage service.

OSC designs this radiator with fitted and torqued components to factory specifications, and each unit is tested multiple times during production. The result is a direct replacement radiator for 2003 Ford Expedition, 2004 Ford Expedition, and 2003-2004 Lincoln Navigator cooling system service where OE-style fit and function are required. This part cross-references Spectra Premium CU2609 and APDI 8012609 for the same application.

Common Problems This Radiator Helps Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or weakened radiator flow
• Transmission fluid temperature issues tied to a failing cooler
• Reduced cooling efficiency from worn core fins or internal corrosion
• Fitment problems after replacing a damaged OE radiator

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and cooler line spacing before installation. Confirm vehicle build date on 2004 Ford Expedition applications, since this part applies to units built before 12/4/03. Flush the cooling system, inspect hoses and clamps, and check the transmission cooler lines for contamination before installing Part Number 2609.

Quality Assurance

OSC Premium radiators are individually pressure tested and produced with OE-style engineering standards. The design includes enhancements aimed at improving durability and cooling performance over the original layout, including upgraded fin density and a larger transmission cooler where applicable.
