⚙️ Key Features

• Rated 30 kPa
• 0.043 kg
• 96 applications across the D, TD, MD, TMD, AD and AQAD series
• Cooling System group

🔌 Function

Seals the cooling system filler neck and holds the coolant under pressure to raise its boiling point, venting through the built-in valve once the rated pressure is exceeded.

⚠️ Common Signs of Failure

• Coolant lost steadily with no leak you can find
• Coolant boiling or pushing out into the expansion tank
• Sealing rubber perished, swollen or flattened
• Cap will not hold its rated pressure on a tester
• Steam or a sweet smell around the filler neck when hot

🛠️ Service Notes

• Match the rating: a cap rated above 30 kPa overstresses hoses and the heat exchanger, one below it vents early and the engine runs hot
• Never release a cap on a hot engine — let the system cool first, as escaping coolant will scald
• Renew the cap whenever the system is drained, and check the filler neck seat for scale or corrosion

📦 Condition
