⚙️ Key Features

• Plug from the Cooling System group
• Listed for four D series engine applications

🔌 Function

Blanks off a coolant drilling or port so the coolant is held in the intended path and nothing escapes from the unused opening.

⚠️ Common Signs of Failure

• Coolant weep or crusty deposits around the plug
• Coolant level dropping with no obvious external leak
• Plug seat corroded or the sealing face pitted
• Threads found damaged or the plug loose on removal
• Air drawn into the circuit, showing as an unstable temperature reading

🛠️ 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
