3804791 Coolant Pump Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a coolant pump, in 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 3801791. That number is not one we list ourselves, so ask for it to be sourced when the exchange is ordered. The other coolant pump cores here are 3804812 and 3804814, and nothing published against them separates one from another, so order the number that matches the coolant pump actually coming off.

⚙️ Key Features

• Core deposit line, not a coolant pump you can fit
• Paired exchange unit is part number 3801791, which we do not list ourselves
• Refunded when the old coolant pump is returned
• Not separable from the other coolant pump cores here, so order by part number
• Cooling System group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the coolant pump itself circulates coolant through the block, the heads 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 pump's telltale hole, with crust and staining round the housing
• Engine running hot or the temperature alarm sounding, worst at sustained high load
• Rumble, growl or squeal from the front of the engine that follows engine speed
• On strip-down, notchy bearings, play at the shaft, and an impeller eroded or loose on its seat

🛠️ 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 3801791
• Renew the gasket or O-ring and the drive belt when the exchange pump goes on, and check the thermostat, the heat exchanger and the raw water side before the pump is blamed for a hot engine

📦 Condition

• Refundable core deposit - not a physical part
