📋 Kit Contents

🔌 Function

Seals a joint or shaft in the cooling circuit so coolant stays in and air stays out.

⚠️ Common Signs of Failure

• Coolant weeping or crusting at the joint
• Ring hardened, flattened or set to the shape of its groove
• Ring split, nicked or extruded out of the groove
• Coolant level falling with no visible external leak at first
• Repeat leak shortly after a previous repair

🛠️ Service Notes

• This ring is part of the gasket kit, so check whether the kit already covers what you need before ordering it separately
• Coolant pipe 831908 also supersedes 850413, so an old listing for that number can point at either part, confirm which you are replacing
• Never refit a used ring, and clean the groove thoroughly before assembly
