Silicone Coolant Hose Kit Blue 2010 6.7L Dodge Cummins

Silicone Coolant Hose Kit for the 2010–2012 6.7L Dodge Cummins improves cooling-system reliability by replacing factory rubber lines with a 100‑percent silicone solution built for long-term heat and age resistance.

This Mishimoto kit is engineered specifically for the 2010–2012 6.7L Cummins platform and replaces the factory upper and lower radiator hoses to restore coolant flow integrity and reduce the risk of swell, cracking, or premature failure encountered with OEM rubber hoses.

• Vehicle-specific fit — Direct replacement for the 2010–2012 6.7L Dodge Cummins radiator hose routing to simplify installation and ensure correct hose lengths and bends.
• 100% silicone construction — Silicone composition provides improved resistance to heat and coolant degradation compared with standard rubber, maintaining flexibility and sealing performance over time.
• Upper and lower hose replacement — Replaces both factory upper and lower radiator hoses to provide a coordinated update to the cooling circuit and eliminate mixed-material connections.
• Mishimoto engineering — Designed by Mishimoto to meet the cooling needs of stock and modified Cummins engines with attention to fitment and durability.

Why this matters

Replacing OEM rubber hoses with a silicone kit reduces the likelihood of coolant loss from hose failure, helps preserve consistent coolant flow under thermal cycling, and lowers maintenance frequency. A vehicle-specific kit avoids trimming or trial fitting, saving installation time and reducing the chance of improper routing.

Installation notes

The kit is intended as a direct-fit upgrade for the stated model years and replaces the factory upper and lower radiator hoses. Use factory-style clamps or equivalent quality hardware for secure, leak-free connections.
