1542512 Plug | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta threaded plug used to close a machined passage in the cylinder-block lubricating and oil system of selected TAD10 and TWD10 engines. The plug seals the unused end of an oil or service gallery in the cylinder block. Correct thread engagement and sealing prevent pressurised engine oil from escaping and keep contamination out of the internal passage.

🔌 Function

The plug seals a threaded or machined opening in an engine circuit so that fluid, oil or pressure cannot escape. It allows the opening to be reopened for service or inspection and then closed again securely.

⚠️ Common Signs of Failure

• Weeping or dripping fluid around the plug seat
• Loss of system pressure in the circuit it seals
• Corrosion, pitting or scale build-up on the plug body
• Damaged, rounded or seized drive recess preventing removal
• Plug working loose or failing to seat correctly after refitting

🛠️ 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
