🔧 Product Description

Genuine Volvo Penta threaded plug used in the lubricating-oil cooler housing on the TAD1240GE. It closes a machined gallery or service opening in the cooler assembly and retains engine-oil pressure.

🚤 Compatibility

  • Engine Family: TAD, D, TWD

Full model list at the end of this description.

⚙️ Key Features

  • Threaded service plug for the oil-cooler housing
  • Confirmed in the TAD1240GE lubrication arrangement
  • Closes an internal oil gallery or machining port
  • Requires the specified sealing component or thread seal
  • Housing threads and plug sealing face must be inspected during service
  • Engine type: Volvo Penta 12-litre industrial diesel
  • Quantity varies by assembly, most commonly one

🔌 Function

Closes and seals an oil-gallery opening in the cooler housing.

⚠️ Common Signs of Failure

  • Engine-oil seepage around the plug
  • Low oil pressure from a leaking gallery
  • Damaged plug or housing threads
  • Rounded or corroded plug head
  • Failed sealing ring or thread seal

🛠️ 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
