3806391 Coolant Pump Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a coolant pump, from the Cooling System group. It is the refundable charge raised against the old coolant pump when the exchange unit is bought, and it comes back once the worn coolant pump is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3803391, which is the number to quote for the component itself and the number to check availability against. It carries a published weight of 13.94 kg, which is the mass of the coolant pump itself and is what to plan the return leg around, since nothing goes out against the deposit. All five coolant pump cores in this listing carry a published weight, and at 13.94 kg this is the largest of the five, so it is the biggest pump of the group going back.

⚙️ Key Features

• Core deposit line, not a coolant pump you can fit
• Belongs with the exchange unit, part number 3803391
• Refunded when the old coolant pump is returned
• Published weight 13.94 kg

🔌 Function

As a line item it carries the refundable core charge on the exchange; the pump itself drives coolant round the block, head and heat exchanger so the heat of combustion is carried away.

⚠️ 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
• Temperature climbing under load, or the engine running hot whenever it is worked hard
• Coolant weeping or dripping from the pump's telltale hole
• A rumble, growl or squeal from the pump that rises and falls with engine speed
• Play felt at the pulley or shaft, or an impeller found eroded and corroded on strip-down

🛠️ Service Notes

• The charge is refunded when the worn coolant pump is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3803391
• Check the belt, tensioner and thermostat before condemning the pump, and renew the pump gasket or seal ring and the coolant when the exchange unit goes on

📦 Condition

• Refundable core deposit - not a physical part
