Detailed Description

Gates 52441 is a molded radiator coolant hose engineered for upper coolant routing in Mack MD6 and Mack MD7 trucks. The EPDM material is commonly used in cooling systems for its resistance to heat and coolant exposure, while the molded profile supports the correct path between connection points. This part number is also referenced as 52441, and it cross-references 23694685 for the same application.

As part of the Gates Molded Coolant Hose line, this hose is part of a broad replacement range covering multiple coolant system layouts. That makes it a practical choice when replacing a formed hose on a Mack MD6 or Mack MD7 and the original routing must be preserved. Part number 52441 is specified for upper positions, including an upper engine-to-pipe application on select MD7 models.

What It Is Used For

• Replacing a cracked or softened upper radiator hose.
• Restoring coolant flow after hose swelling or collapse.
• Correcting leaks at formed hose connection points.
• Maintaining the original hose routing in the cooling system.
• Addressing fitment issues on Mack MD6 and Mack MD7 coolant service.

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Confirm whether the vehicle uses an upper or upper engine-to-pipe configuration, since fitment varies by application. Inspect adjoining clamps, pipes, and sealing surfaces for wear before installing the new hose.

Quality Assurance

Gates manufactures molded coolant hoses to OEM-quality specifications for replacement use. The 52441 part number is built to match application-specific coolant hose requirements for Mack MD6 and Mack MD7 fitments.
