Overview

This Gates radiator coolant hose is a molded silicone replacement for select Mack CXU applications. Built for upper cooling-system routing, it follows the OE-style shape needed for a clean, direct hose path and reliable coolant transfer. Part number 28375 is a fitment-specific solution for Mack CXU trucks with the listed upper hose configurations.

Key Features

Detailed Description

Gates 28375 is a molded coolant hose designed for upper radiator hose routing on select Mack CXU trucks. The silicone material supports demanding cooling-system conditions, while the formed profile helps maintain the correct path between the radiator and pipe connections. For buyers searching for a Mack CXU upper radiator hose or a molded silicone coolant hose, this part number 28375 provides a direct-fit replacement option for the listed applications. This part cross-references Monroe Shocks & Struts (e.g., 11MF4723M, H19775) for the same application.

What It Helps Address

  • Cracked or deteriorated coolant hose material.
  • Incorrect hose shape that does not follow the factory routing.
  • Improper sealing at the hose ends.
  • Cooling-system service needs on upper hose connections.

Installation Notes

Verify the hose end diameters and centerline length against the removed part before installation. Confirm whether your Mack CXU uses the upper pipe-to-radiator or upper radiator-to-pipe configuration shown in the fitment data. Inspect adjoining clamps, pipes, and sealing surfaces for wear before installing the new hose.

Quality Assurance

Gates states that this silicone molded coolant hose is built to exceed OE hose performance expectations.
