Product Details
This Dorman radiator coolant hose O-ring is built from EPDM, a material commonly used in cooling system service because it handles coolant exposure and temperature cycling. The round profile and multiple OE-style dimensions support a precise seal at the hose connection point. If the hose itself is still serviceable, replacing the O-ring can be a practical repair instead of changing the full assembly. Part number 926-159 is also referenced by BC3Z8590A for the same application.
What It Helps Fix
- Coolant seepage at the radiator hose connection
- Sealing issues caused by a worn or flattened O-ring
- Loss of coolant from a damaged hose-end seal
- Service calls where the hose assembly is still usable
- Cooling system maintenance on Ford F-250 Super Duty and Ford F-350 Super Duty trucks
Installation Notes and Tips
Inspect the hose end, sealing surface, and mating components before installation. Clean the groove and contact area thoroughly, then compare the replacement O-ring dimensions to the original seal before assembly. Use proper coolant service procedures and verify there are no leaks after the system is reassembled. Confirm fitment for your specific 2011-2018 Ford F-250 Super Duty or 2011-2018 Ford F-350 Super Duty application before ordering.
Quality Assurance
Dorman supplies aftermarket replacement parts focused on restoring original function with application-specific fitment. Part number 926-159 is built as a service replacement for select Ford Super Duty cooling system applications.
