# 3806516 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 3803516, which is the number to quote for the component itself. The other coolant pump core here is 3806537; only one of the two carries a published weight, so there is nothing to choose between them on paper - order the number that matches the coolant pump actually coming off.

## ⚙️ Key Features

-   Core deposit line, not a coolant pump you can fit
-   Belongs with the exchange unit, part number 3803516
-   Refunded when the old coolant pump is returned
-   Not separable from coolant pump core 3806537, 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 drives coolant round the block, head and heat exchanger so the engine sheds its heat at a steady temperature.

## ⚠️ 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
-   Engine temperature climbing under load, or an overheat alarm at the helm
-   Coolant dripping from the pump's tell-tale drain hole
-   A rumble or growl from the pump, with play felt at the pulley or shaft
-   Coolant loss traced to the pump seal, or the impeller found corroded and eroded

## 🛠️ 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 3803516
-   Prove the thermostat, heat exchanger and belt tension before condemning the pump, and renew the gaskets and belt at the same time

## 📦 Condition
