⚠️ Common Signs of Failure

• Coolant weeping or salt crusting at the joint face
• Corrosion or pitting on the sealing face
• Casting cracked, or studs and threads corroded
• Internal face scaled or eaten away on the raw water side
• Fixings seized so the cap cannot be drawn off squarely

🛠️ Service Notes

• At 9.026 kg this is a large casting rather than a small screw cap, so plan to support it during fitting
• Renew the gasket and any sacrificial anode behind it, and clean both faces back to bare metal
• The lighter Cooling System caps 3828249 at 4.97 kg and 3828601 at 1.835 kg are separate parts, so check the fitment before ordering
