# 3830046 Water Pump | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta water pump from the Cooling System group, weighing 6.718 kg and listed for 4 applications across TWD and TAD series engines. It supersedes part number 11030791, which was catalogued earlier as a pump housing, so the change from housing to complete pump matters when comparing prices or checking what is in the box.

## 🚤 Compatibility

-   Volvo Penta TWD1240VE
-   Volvo Penta TAD1241VE
-   Volvo Penta TAD1242VE
-   Volvo Penta TAD1241-42VE

-   **Engine Family:** TWD, TAD

## ⚙️ Key Features

-   Supersedes 11030791, previously listed as a pump housing
-   6.718 kg
-   4 applications across TWD and TAD engines
-   Complete pump assembly

## 🔌 Function

Circulates coolant through the engine and its heat exchange components whenever the engine is running, maintaining flow at all speeds.

## ⚠️ Common Signs of Failure

-   Coolant dripping from the pump's weep hole or shaft area
-   A rumble, growl or whine from the pump that changes with engine speed
-   Overheating with a full system and a sound thermostat
-   Play felt at the pulley when the belt is off
-   Crusted coolant trails down the front of the engine

## 🛠️ Service Notes

-   Because the superseded number was listed as a housing rather than a pump, confirm the supplied part is the full assembly before stripping the engine down
-   Renew the drive belt and check pulley alignment while the pump is off
-   Flush the system and fit fresh coolant; debris from a failed pump circulates through the whole circuit
