🔌 Function

Seals the 45 mm casting aperture in the cylinder block or cooling jacket. Clean and inspect the bore, apply the specified sealant and drive the plug squarely to the correct depth.

⚠️ Common Signs of Failure

• Coolant seepage or rust staining around the plug
• Perforation from internal or external corrosion
• Plug movement or partial release from the bore
• Coolant loss and engine overheating
• Repeat leakage caused by a pitted or oversized block aperture

🛠️ Service Notes

• Clean the bore out to bare, sound metal and check it for corrosion, pitting or a raised lip — a plug will not seal in a wasted or scored bore, and that bore may need attention first
• Fit the plug square to the bore and drive it evenly with a tool or socket that bears on the correct part of the plug, to the depth the manual specifies; driven in cocked or too deep it will leak
• Seal it with a sealant of the type specified for that joint, not with a silicone or rubbery compound, which is slippery and lets a plug creep out under pressure
• With an expanding rubber type, seat it fully, then tighten the centre nut to expand it against the bore and check it again after the first heat cycle
• Fill, pressure-test or run the system and check the plug for weeping before closing up access, since many of these sit where you cannot see them once the engine is back together
