Mishimoto Aluminum Heater Supply and Return Hose CNC Fitting Set for 2011-2025 Dodge Durango & Jeep Grand Cherokee

Fits 2011-2025 Dodge Durango and Jeep Grand Cherokee models.

The factory quick-disconnect heater hose fittings on 2011-2025 Dodge and Jeep SUVs are a notorious failure point. Manufactured from brittle plastic, the OE components frequently crack under constant heat cycles and cooling system pressure, leading to sudden coolant loss and potential engine overheating. The Mishimoto MMFT-HH-5858-90 fitting set provides a permanent solution by replacing these weak connections with high-strength, CNC-machined aluminum.

This direct-fit upgrade installs efficiently without requiring the replacement of the entire heater hose assembly or difficult access behind the firewall. These fittings are engineered to withstand pressure spikes during hard acceleration and the intense heat soak associated with extended idling. Each set includes both the supply and return fittings to fully reinforce the vehicle's cooling system reliability.
