11XX Series Humvee Electric Heater Core Valve — Direct, Better‑Than‑OEM 24V Replacement (Factory Plug, Plug‑and‑Play)

Restore proper HVAC function in your 11XX series Humvee with this upgraded electric heater core valve. The OEM oil‑actuated valve is prone to slow or incomplete closing and becomes very hot during operation, often causing uneven cabin temperatures (cold in the rear, hot in the front). Our Black Dog electric valve replaces that design with a 24V solenoid that closes instantly and remains cool, delivering consistent, reliable flow control. Designed as a direct, better‑than‑OEM swap, the valve uses the factory electrical plug for a true plug‑and‑play install — no cutting, splicing, or modifications required. Built with durable materials to withstand military and heavy‑duty use, this valve improves responsiveness and longevity of your Humvee’s heater core system. What’s included 1x 11XX Series Electric Heater Core Valve (24V) with factory plug Installation instructions Fitment & note Intended for 11XX series Humvees. Confirm your vehicle series and connector type before ordering. Replaces OEM oil‑actuated heater core valve; recommended when rear cabin blows cold while front remains hot.
