🔌 Function

Dampens vibration and resonance in the rigid coolant-pipe assembly.

⚠️ Common Signs of Failure

• Coolant pipe vibrating or droning
• Repeated pipe or hose-joint fatigue
• Balance weight loose or missing
• Bracket or pipe cracking
• Coolant leak caused by excessive movement

🛠️ Service Notes

• If the coolant pipe assembly is renewed, transfer or refit this balance weight in its original position between the two pipes, since removing it reintroduces the resonance it is fitted to control
• Renew the cable ties (948211) securing the pipework at the same time as this weight, since ties lose their grip once cut or removed
• Check the nearby hose clamps (20405755, 943480) for tightness while the pipework is disturbed
