Dorman 626-749 Engine Coolant Overflow Hose
Engine Coolant Overflow Hose for Super Duty
Dorman 626-749 is an engine coolant overflow hose assembly for select Ford Super Duty trucks. It replaces the original coolant overflow hose design with an upgraded aluminum T-connector to address a common failure point in the factory part.
- OE FIX replacement for the coolant overflow hose assembly
- Upgraded aluminum T-connector helps reduce repeat cracking issues
- Molded hose assembly for a direct-style routing layout
- Black hose construction with metal, rubber, and plastic materials used in the assembly
- 46 in. overall length with 0.35 in. inside diameter and 100 PSI maximum working pressure
- Heat shield included
- Standard replacement grade
Fitment Details
Compatible with 2017-2019 Ford F-250 Super Duty, to left coolant reservoir, and 2017-2019 Ford F-350 Super Duty, to left coolant reservoir. This Dorman 626-749 coolant overflow hose is built for the Ford F-250 Super Duty and Ford F-350 Super Duty applications listed above, with fitment matched to the left coolant reservoir routing.
This part cross-references Ford OE numbers HC3Z8075D and HC3Z8075K for the same application.
What It Helps Fix
- Cracked or split coolant overflow hose sections
- Failure at the plastic T-connector on the original assembly
- Coolant seepage around the overflow hose routing
- Loss of proper coolant reservoir connection
- Heat-related deterioration in the hose assembly
Installation Notes
Verify routing to the left coolant reservoir before installation. This molded assembly uses hose-style end connections and does not include clamps. Confirm the vehicle’s existing hose path, connector orientation, and diameter match before replacement. Dorman 626-749 is a direct-fit style service part for the listed Ford Super Duty applications.
Quality Assurance
Dorman engineered this OE FIX replacement to improve on the original design by using an aluminum T-connector instead of the factory plastic version. That material change targets a known failure area in the coolant overflow hose assembly for long-term serviceability.
