⚙️ Key Features

• 5.466 kg
• Supersedes 3854103
• Engine group
• No published applications
• Also supersedes Volvo part number 857203

🔌 Function

Holds the oil charge below the crankcase, lets it settle and cool, and forms the drain point and the reservoir the pump draws from.

⚠️ Common Signs of Failure

• Oil weeping from the sump flange or drain plug
• Pan dented or gouged by a grounding or a careless lift
• Flange distorted by overtightening, so it will not seal on a new gasket
• Drain plug thread pulled or its boss cracked
• External corrosion pitting

🛠️ Service Notes

• The other sump in this round is 3857778 at 3.651 kg with a metric drain and 242 published applications, so this heavier one is a distinctly different pan — check drawing before ordering
• The number it replaces, 3854103, is also listed against hollow screw 3857674, so that old number on its own is not enough to identify what you need
• Fit a new gasket or the specified sealant, tighten in sequence to the published figures, and check the drain plug seal
