Show original supplier description
The stock quick-disconnect heater hose fittings on the 2011+ Dodge Durango and Jeep Grand Cherokee are a known failure point due to their brittle plastic construction, which can crack under heat and pressure, leading to coolant loss and breakdowns. Mishimoto's Heater Supply & Return Hose Fitting Set offers a direct-fit replacement, utilizing CNC-machined aluminum for superior durability and resistance to repeated heat cycles. The use of double FKM O-rings guarantees a leak-free seal under high pressure, providing a permanent solution to a common failure point. Key benefits include enhanced durability over stock plastic fittings, a leak-free seal provided by FKM O-rings, and a straightforward installation process. This kit is compatible with 2011-2025 Dodge Durango models and 2011-2023 Jeep Grand Cherokee models. The Mishimoto Heater Supply & Return Hose Fitting Set is backed by the Mishimoto Lifetime Warranty.
