Heater hose assemblies are exposed to harsh conditions, often causing inferior plastic materials to become brittle and crack. Especially in more complex, multipiece assemblies, you need more durable replacements to ensure a reliable repair. That's where Dorman expertise makes all the difference.
Focusing on complex heater hose assemblies, we rigorously engineer our solutions to endure even the most unforgiving underhood conditions. Many of our Dorman heater hose assemblies feature upgraded metal connectors to help prevent future failures—and it's all backed by our limited lifetime warranty.

Although they perform a vital function, many of the more complicated OE heater hose assemblies fail to stand the test of time. Our OE FIX parts resolve these issues with smart design choices and upgraded materials, ensuring years of reliable service—and far fewer comebacks for you.
This OE version of this part has a brittle hose connection that we know to be prone to cracking and leaking, especially when subjected to extreme underhood conditions.
Our OE FIX solution features a redesigned mating connector to eliminate the brittle hose connection and provides a more secure connection to the water outlet for a longer service life.
