• Header tank level dropping with no external puddle until pressure is applied

🛠️ Service Notes

• Coolant pipe 3843049 carries the same 9 D series applications at 1.481 kg, so check the routing as well as the number
• Renew the O-rings, seals and clamps at each joint when the pipe is fitted
• Support a run of this size in its original clips so the joints are not carrying its weight
