GPD 1713562 Octovalve Assembly EV Thermal Management Coolant Control Valve

The GPD 1713562 Octovalve Assembly is a direct-fit replacement thermal management coolant control valve designed for electric vehicles equipped with the OEM Octovalve heat pump system. This precision-engineered assembly restores proper coolant routing and thermal regulation to the vehicle's integrated heat pump circuit.

The Octovalve is a rotary valve featuring eight ports that directs glycol-based coolant flow through multiple operating loops to manage heating and cooling demands across the vehicle's powertrain, battery pack, power electronics, and cabin HVAC system. A built-in electric stepper motor actuator adjusts valve position in response to real-time thermal demands, enabling the system to operate in multiple distinct coolant circuit configurations.

Key Features:

• Eight-port rotary valve design controls coolant flow across multiple thermal loops
• Integrated electric stepper motor actuator for precise, electronically controlled positioning
• Manages coolant distribution to motors, battery pack, power electronics, and cabin systems
• Replaces the OEM Octovalve unit in the vehicle's Supermanifold thermal assembly
• Engineered to meet or exceed original equipment fit, form, and function specifications
• Supports heat pump operation including simultaneous heating and cooling functions

The Octovalve mounts directly to the vehicle's Supermanifold and connects via a low-voltage electrical harness. Proper installation requires ensuring the alignment dowels engage the Supermanifold fully before fastener installation. After replacement, a coolant valve function test and coolant air purge procedure should be performed using the vehicle's service mode or diagnostic software to verify correct operation.
