⚙️ Key Features

• Cooling system filler cap
• 0.116 kg
• Listed for 75 applications across D and MD series engines

🔌 Function

Seals the coolant filler and holds the system at its working pressure, raising the boiling point and letting coolant flow back from the expansion side as the engine cools.

⚠️ Common Signs of Failure

• Coolant disappearing with no pool or drip to find
• Steam or coolant escaping around the filler neck
• Running hot under load, then settling once the cap is loosened
• Rubber seal on the underside swollen, perished or set hard
• Pressure valve stuck or its spring weak when the cap is tested

🛠️ Service Notes

• Pressure-test the cap before condemning the expansion tank or the exchanger - a tired cap gives the same symptoms as a leak
• O-rings 23265130 and 23265133 share this cap's 75-application fitment, so check the assembly for which seals are wanted alongside it
• Never open a hot system

📦 Condition
