Product Description
MOPAR 5179086AA RIGHT SIDE COOLANT TUBE CONNECTOR ELBOW FOR 03-07 DODGE WITH 5.9L CUMMINS ENGINE
Maintain proper cooling system performance and restore OEM reliability with the genuine Mopar 5179086AA Right Side Coolant Tube Connector Elbow for 2003-2007 Dodge Ram trucks equipped with the legendary 5.9L Cummins diesel engine. Engineered to factory specifications, this OEM coolant tube elbow plays a critical role in the engine oil cooler and coolant circulation system, ensuring dependable cooling performance under towing, hauling, and heavy-duty operating conditions.
The Mopar 5179086AA connector elbow, also referenced as an oil cooler hose coupler elbow, is designed to provide a secure coolant passage connection while withstanding extreme engine temperatures and pressure cycles common in Cummins-powered diesel trucks. Over time, factory coolant elbows and rubber components can become brittle, crack, or deteriorate due to prolonged heat exposure and age, potentially causing coolant leaks, cooling inefficiency, or contamination within the system.
Manufactured using OEM-grade materials for durability and direct-fit installation, this genuine Mopar replacement elbow ensures proper fitment, leak-free sealing, and long-lasting reliability. Unlike low-quality aftermarket alternatives, genuine Mopar cooling components maintain factory performance standards and proper coolant flow characteristics.
This coolant tube connector elbow replaces Mopar part numbers 5086942AA and 5086942AB while preserving OEM compatibility with select Dodge Ram 2500 and 3500 diesel applications equipped with the 48RE automatic transmission.
