Mishimoto 2011+ Dodge Durango Heater Supply and Return Hose CNC Fitting Set
SKU: M00C MMFT-HH-5858-90
Description
Part #: MMFT-HH-5858-90
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 pressuredumping 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.
