3806844 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 3803844, which is the number to quote for the component itself. The other two coolant pump cores here are 3806869 at 4.536 kg, only about 450 grams away and no safe way to choose between the two, and 3806839 at 8.165 kg; order the number that matches the pump actually coming off. The 4.082 kg published against the line is the figure to plan the return carriage of the old coolant pump around, since the deposit itself ships nothing.

⚙️ Key Features

• Core deposit line, not a coolant pump you can fit
• Belongs with the exchange unit, part number 3803844
• Refunded when the old coolant pump is returned
• 4.082 kg published, about 450 grams from coolant pump core 3806869
• Cooling System group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the pump itself drives coolant round the engine, holding the flow up through the block, the head and the heat exchanger so the heat goes overboard instead of into the castings.

⚠️ 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
• Temperature climbing under load, or the header tank losing coolant with no leak to be found
• Whine, rumble or grinding from the pump end of the engine
• Play or wobble felt at the pulley or the impeller shaft

🛠️ 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 3803844
• Renew the drive belt, the thermostat and the coolant while the front of the engine is open, and establish where the old pump's coolant was going before the exchange unit goes on

📦 Condition

• Refundable core deposit - not a physical part
