Mishimoto Heater Hose CNC Fitting Set 2011 Dodge Durango

Mishimoto Heater Hose CNC Fitting Set for the 2011 Dodge Durango replaces brittle factory quick-disconnect heater hose fittings to eliminate coolant leaks and restore dependable coolant containment under heat and pressure.

This direct-fit fitting set replaces the stock plastic quick-disconnects on 2011+ Dodge Durango models, addressing a known failure point where brittle components crack and allow coolant loss. The design focuses on durability and serviceability to reduce roadside failures and maintenance downtime.

• CNC-machined aluminum construction — provides a uniform, precisely-toleranced mating surface that resists cracking and deformation compared with factory plastic fittings, helping maintain a leak-free seal under thermal cycling.
• Direct-fit replacement — installs in the factory locations without modification, simplifying replacement and preserving original routing and connections for a straightforward service procedure.
• Replaces brittle quick-disconnects — eliminates the common plastic failure mode that leads to sudden coolant loss, improving long-term reliability and reducing the risk of being stranded due to a coolant leak.
• Designed for thermal and pressure resilience — the material choice and machining standard help the fittings withstand the heat and system pressure experienced in heater hose circuits, maintaining coolant system integrity.

Mishimoto’s reputation for motorsports-grade cooling components informs the design intent: focused on functional durability, precise fitment, and consistent performance in demanding conditions.

What this kit solves: replaces weak, heat-sensitive factory fittings that commonly fail on the 2011+ Durango, restoring a robust connection in the heater hose circuit to prevent coolant loss and associated engine overheating or vehicle downtime.
