# 3806210 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 3803210, which is not a number we carry ourselves, so ask us to look the exchange unit up before you order against it. It is published at 10.886 kg, and the nearest published figure among the coolant pump cores here is 3806202 at 9.071 kg, 1.815 kg away. Not all ten carry a published weight, so the set cannot be ranked by mass.

## ⚙️ Key Features

-   Core deposit line, not a coolant pump you can fit
-   Belongs with the exchange unit, part number 3803210
-   Refunded when the old coolant pump is returned
-   Published at 10.886 kg
-   Nearest published figure here is 3806202 at 9.071 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 engine holds its working temperature under load.

## ⚠️ 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
-   A rusty stain or dried salt trail below the pump housing
-   The engine running hot when it is worked, and slow to come back down afterwards
-   Bearing noise from the front of the engine that changes with speed rather than with load
-   On strip-down, an impeller found corroded or eroded with the vanes eaten away

## 🛠️ 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 is the deposit that rides beside the exchange unit, part number 3803210, which we do not list ourselves, so ask us to look it up before ordering
-   Renew the gasket or sealing ring and check the belt, tensioner and drive pulley while the pump is off, and flush the system through if the old pump has been shedding corrosion
