# 3804576 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 3801576, which is the number to quote for the component itself. It is one of 8 coolant pump cores running through this block, and nothing published against them separates one from another, so order the number that matches the coolant pump actually coming off rather than working from the description.

## ⚙️ Key Features

-   Core deposit line, not a coolant pump you can fit
-   Belongs with the exchange unit, part number 3801576
-   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 pump itself circulates coolant through the block, head and heat exchanger so combustion heat 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
-   Coolant weeping or dripping from the tell-tale hole under the pump body
-   Temperature climbing under load with the header tank going down and no other leak found
-   Rumble, squeal or grinding from the pump that rises and falls with engine speed
-   On removal, play or roughness at the shaft, a corroded or eroded impeller and coolant tracking behind the seal

## 🛠️ 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 3801576
-   Renew the drive belt, thermostat and hoses while the front of the engine is open, and flush the system before the exchange pump goes on
