🔌 Function

The washer sits under a fastener or between mating cooling-system components to distribute clamping force evenly and protect the contact face. This helps keep the joint tight and leak-free through the engine's heating and cooling cycles.

⚠️ Common Signs of Failure

• Coolant or raw water seepage around the fastener or joint face
• Visible corrosion, pitting or scaling on the washer surface
• Deformed, dished or cracked washer that no longer seats flat
• Fastener repeatedly losing torque or working loose in service
• Scoring or damage to the mating surface where the washer bears

🛠️ 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
