## 🔌 Function

The plug seals a threaded or machined opening in an engine housing, passage or component so that oil, coolant, fuel or pressure cannot escape. It also provides a removable access point for draining, filling or servicing that passage.

## ⚠️ Common Signs of Failure

-   Seepage, weeping or dripping around the plug seat
-   Damaged, corroded or pitted sealing face that will no longer seal
-   Stripped, cross-threaded or rounded threads preventing correct torque
-   Plug loosening in service and causing pressure or fluid loss
-   Corrosion or seizing that makes removal during servicing difficult

## 🛠️ 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
