⚙️ Key Features

🔌 Function

Spreads the clamping load of a terminal or fastener and helps hold the electrical joint tight.

⚠️ Common Signs of Failure

• Terminal or fastener working loose in service
• Corrosion or green deposit around the joint
• Washer distorted, dished or cracked
• Heat discolouration around the connection
• Intermittent supply on the circuit the joint serves

🛠️ Service Notes

• Check you are fitting the same type of washer that came out — plain, hardened, sealing and locking washers are not interchangeable, and the wrong one either fails to seal or fails to hold
• Treat sealing washers on fuel, oil and coolant unions as single-use; they seal by deforming onto the faces, so a used one will not seal reliably a second time
• Clean the seating faces and make sure the washer sits flat and square, fully under the head or nut, before tightening — a washer trapped on a chamfer or edge will crush unevenly
• Tighten the fastener to the figure given in the workshop manual for your engine, and account for every washer on reassembly so none is left loose inside a housing or the engine bay
