Detailed Description

OSC Part Number 2186 is a replacement radiator designed around original equipment dimensions and cooling layout for Dodge Dakota and Dodge Durango models with auxiliary transmission oil cooler equipment. The radiator uses a crossflow configuration, plastic tanks, and a PA core, with a concentric transmission cooler integrated into the assembly. OSC also uses premium-grade tubes, fins, headers, tanks, and related components, along with a die-cut gasket to help maintain a leak-resistant seal. Each unit is pressure tested during production, and the design includes engineering updates aimed at improving cooling performance and service life in higher-mileage vehicles. This part cross-references APDI 8012186 for the same application.

Common Cooling Issues It Can Address

• Coolant leaks from a worn or damaged radiator tank or core
• Transmission temperature concerns tied to a failing integrated cooler
• Overheating caused by restricted flow or reduced heat transfer
• Fitment problems from a radiator that no longer matches factory dimensions
• Cooling system service needs on 1997-1999 Dodge Dakota and 1998-1999 Dodge Durango models

Installation Notes and Tips

Verify that your vehicle is equipped with auxiliary transmission oil cooler plumbing before ordering. Confirm inlet and outlet sizes, cooler line routing, and overall core dimensions against the original radiator. Part Number 2186 is engineered for drop-in style replacement, but final installation should always follow factory service procedures and include a full cooling system inspection after installation.

Quality Assurance

OSC tests the radiator core before assembly, then tests the completed unit again after assembly. The transmission and engine oil cooler circuits are also tested prior to installation into the tank. This production process is used to verify sealing, cooler integrity, and overall radiator performance before the part is released for service.
