Mishimoto 2011+ Dodge Durango Heater Supply and Return Hose CNC Fitting Set

The stock quick-disconnect heater hose fittings on the 2011+ Dodge Durango are a common failure point. Made from brittle plastic, they crack under heat and pressure*dumping coolant and leaving you stranded. This direct-fit CNC-machined aluminum fitting set replaces those weak connections without replacing the entire heater hose assembly or going through the firewall. It*s a simple, permanent fix that installs easily with basic tools.

Failure typically happens when the engine is heat-soaked from extended idling and then sees a spike in pressure during hard acceleration. These aluminum fittings are built to handle that stress without cracking, unlike the brittle factory plastic. Installation is simple and straightforward and doesn*t require going through the firewall. This heater hose fitting is backed by the Mishimoto Lifetime Warranty.
