For Nissan Armada 04-15 5.6L Infiniti QX56 06-10 Heater Inlet Hose Control Valve

Heater Inlet Hose Control Valve for Nissan Armada and Infiniti QX56

This heater inlet hose control valve regulates coolant flow into the heater core, letting the cabin heat respond the way it should on your 5.6L powered SUV.

Overview

This heater inlet hose control valve is the inline coolant shutoff that manages flow to the heater core on 5.6L equipped SUVs. A failed heater inlet hose control valve can leave you with no cabin heat or a leak at the hose junction, so replacing it restores normal climate control function. It is aimed at DIYers and shops servicing older full size SUVs that need a direct fit replacement.

Good To Know

Q: What happens if the heater inlet hose control valve fails? A: A failed valve commonly causes no cabin heat or a coolant leak at the hose connection. Replacing it restores normal coolant flow to the heater core.

Q: Do I need to drain the cooling system to replace it? A: Yes, the coolant level must be lowered below the valve before removal to avoid spillage. Refill and bleed the system afterward.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
