3804418 Coolant Pump Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a Volvo Penta coolant pump, from the Cooling System group. It is an accounting line rather than a fittable part: the refundable charge raised against the old coolant pump when a replacement is supplied on exchange, credited back once that worn unit is returned. Ordering it supplies nothing in itself. It is raised against unit 3801418. Core numbers in this series run three thousand above the unit they belong to, so the deposit and the unit are read as a pair.

⚙️ Key Features

• Refundable core deposit on a coolant pump, not a fittable part
• Credited back on return of the old coolant pump
• Pairs with unit 3801418, three thousand below this core number

🔌 Function

Holds the refundable deposit raised against the old coolant pump when a replacement is bought on exchange, and releases it as a credit when that unit is returned. It does no mechanical work. The coolant pump itself drives coolant round the block, the cylinder head and the heat exchanger so the engine sheds its heat.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the coolant pump being exchanged
• Coolant weeping or dripping from the telltale hole under the pump
• Temperature climbing under load, or coolant disappearing with no leak you can find
• Rumbling, growling or squealing from the pump bearing
• Play or roughness felt at the pulley when the belt is off

🛠️ Service Notes

• The deposit is refunded when the old coolant pump is sent back, so return it complete and as it came off - the credit depends on the core being fit to rebuild, and a stripped or broken-up unit can lose it
• Ordering this line on its own supplies no part. It has to go on the order alongside unit 3801418, which is the item that actually ships
• 3804404 and 3804418 are both coolant pump cores with nothing on either line to separate them - order by part number

📦 Condition

• Refundable core deposit - not a physical part
