🔌 Function

Seals a joint in the water pump so coolant cannot escape past the mating faces.

⚠️ Common Signs of Failure

• Coolant weeping from the water pump joint
• Dried coolant trail or crust below the pump
• Ring flattened or hardened when the pump is opened
• Coolant level falling slowly with no other leak found
• Pump housing faces stained where coolant has tracked out

🛠️ Service Notes

• Repair kit 276814 carries this ring along with the pump's other seals, and is usually the better buy when the pump is already apart
• O-ring 925262 is the other ring listed for the same kit and pump, at 0.005 kg, so check which one you are short of before ordering
