⚙️ Key Features

  • Six plugs used in the applicable six-cylinder assembly
  • Designed for engine oil/coolant pressure and temperature
  • Individual service plug
  • Seal or thread compound is separate where specified
  • Engine type: Volvo Penta 12.8-litre inline six-cylinder diesel
  • Quantity varies by assembly, most commonly six

🔌 Function

Closes the machined engine gallery so the internal oil or coolant circuit remains sealed and clean.

⚠️ Common Signs of Failure

  • Fluid seepage around the plug
  • Damaged or crossed threads
  • Plug loosening after heat cycling
  • Missing sealing compound or washer
  • Cracked gallery boss from overtightening

🛠️ Service Notes

  • Clean the threads and the seating face before fitting, and make sure the opening itself is clear of old sealant, swarf and corrosion
  • Renew the sealing washer or O-ring where one is fitted rather than reusing a flattened one, and only use thread sealant where the workshop manual for your engine calls for it
  • Tighten to the figure given in the workshop manual for your engine — plugs in aluminium and other soft castings strip easily, and a plug pulled up hard to cure a leak usually distorts the seat and makes it worse
  • Where the plug closes an oil, fuel or coolant passage, run the engine up to temperature afterwards and check the joint under pressure before signing the job off
  • Keep removed plugs paired with the holes they came out of during a strip-down — plugs of very similar appearance often differ in thread, reach or sealing type
