(MCC) 26-0650 Heater Control Valve (12V) | 5/8" Hose Barb | Fits Carrier/Sutrak Bus HVAC Systems | Replaces T4055 & 260650

Restore Heat to the Driver's Seat.The Mobile Climate Control 26-0650 is the OEM replacement heater valve for thousands of transit and coach buses on the road today. Originally designed for Carrier / Sutrak systems, this valve controls the flow of hot engine coolant to your heater cores.Common Symptoms of Failure: No Heat: The valve is stuck closed, leaving the driver freezing. Weak A/C: The valve is stuck open, allowing hot water to circulate when the A/C is on (overpowering the cooling). Leaking: Coolant dripping from the valve body.Why Buy Genuine MCC? Aftermarket valves often struggle with the vibration and voltage spikes found in heavy-duty buses. This unit is built to MCC's transit-grade standards for longevity in stop-and-go city fleets.Technical Specs: Voltage: 12 Volts Ports: 5/8" Hose Barb Application: Coolant / Water

• FIXES "NO HEAT" & DEFROSTER ISSUES: Genuine MCC Part # 26-0650. The primary electronic water valve used to control coolant flow to the driver's defroster core and passenger heater coils in Transit Buses and Motorcoaches.
• THE "CARRIER" REPLACEMENT: Mobile Climate Control (MCC) is the OEM manufacturer for legacy Carrier Transicold and Sutrak bus AC systems. This valve is the direct replacement for the older Carrier-branded 5/8" heater valves found on MCI, Prevost, and Gillig buses.
• 12-VOLT ELECTRONIC ACTUATOR: Features a high-torque 12V DC motor for reliable "Open/Close" actuation. Unlike vacuum valves that leak, this motorized unit ensures positive shut-off to prevent hot coolant from entering the AC system during summer (fighting the A/C).
• HEAVY-DUTY 5/8" BARB CONNECTIONS: Standard 5/8" inlet and outlet ports designed for standard heater hose. The glass-filled nylon body resists corrosion from old coolant and road salts.
• FLEET COMPATIBILITY: Direct fit for various systems using the T4055 style actuator. Common on Nova Bus, New Flyer, and shuttle buses utilizing rear auxiliary heater loops.
