⚙️ Key Features

  • Controls bypass or overflow flow
  • Calibrated opening characteristics
  • OEM thread and sealing geometry
  • Also supersedes Volvo part number 3812314

🔌 Function

The valve regulates coolant overflow or bypass flow as system pressure and temperature change.

⚠️ Common Signs of Failure

  • Coolant loss
  • Overheating or slow warm-up
  • Excessive system pressure
  • Valve stuck open or closed

🛠️ Service Notes

  • Treat it as a sealed, non-adjustable unit — renew it rather than attempting to clean, shim or adjust the internals
  • Work clean: cap the openings, wipe the area down before opening the fuel system, and do not let dirt or fibres into the fuel side while the valve is off
  • Renew the sealing washers, O-rings or gasket that come with the valve, and never reuse a crushed copper or aluminium washer
  • Tighten to the figure in the workshop manual for your engine; these valves screw into fuel housings and heads that strip readily
  • Bleed and prime the fuel system as the manual for your engine describes, then run the engine and check the joint for weeping under working pressure
