3804900 Coolant Pump Core | Genuine Volvo Penta Part

🔧 Product Description

A core deposit is an accounting line rather than a fittable part: it is the refundable charge raised against the old coolant pump when an exchange coolant pump is bought, and ordering it sends nothing out. Volvo Penta numbers a core deposit 3000 above the unit it belongs to, which puts this one against 3801900. We do not list 3801900 ourselves, so order it through the supplier of the exchange coolant pump. Near-identical coolant pump deposits sit alongside it, among them 3804893, 3804909 and 3804872, and nothing in our records separates one from another, so order by the number of the coolant pump being exchanged. Until the old coolant pump is returned the deposit stays on the account.

⚙️ Key Features

• Refundable core charge, not a part that ships
• Sits against unit 3801900, which we do not list
• Raised against the old coolant pump on an exchange purchase
• Near-identical siblings include 3804893 and 3804909
• Credited when the old coolant pump is returned

🔌 Function

Carries the refundable core charge on a coolant pump exchange. It ships nothing itself; the pump it stands against circulates coolant through the block, head and 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 pump's telltale hole
• Temperature climbing under load, or full overheating
• Rumbling or grinding from the pump, and play felt at the pulley or shaft
• Eroded, corroded or loose impeller blades found on strip-down

🛠️ Service Notes

• Ordering this line on its own supplies no coolant pump. It is the deposit that rides alongside the exchange unit, so the coolant pump itself has to be ordered as a separate line.
• The charge is refunded when the old coolant pump comes back to us complete and rebuildable; a unit that has been stripped for parts, broken up or damaged in transit is normally refused for credit.
• Renew the pump gasket or O-rings and check the drive belt, tensioner and thermostat at the same time, as a seized pump often takes the belt with it.

📦 Condition

• Refundable core deposit - not a physical part
