🔌 Function

The washer distributes clamping load from a bolt or nut across the mating surface and helps maintain correct joint tension. It also protects the component face from scoring and localised stress as the fastener is torqued.

⚠️ Common Signs of Failure

• Visible flattening, distortion or loss of spring tension
• Corrosion, pitting or scaling on the washer faces
• Cracking or splitting around the bore or outer edge
• Fasteners repeatedly working loose or failing to hold torque
• Scoring, galling or fretting marks on the adjacent mounting surface

🛠️ 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
