3806915 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 3803915, which is the number to quote for the component itself. We list that number as a coolant pump, reman. The three coolant pump cores here are well separated by mass - this one at 5.443 kg, 3806930 at 3.742 kg and 3806970 at 1.134 kg - so they are plainly three different pumps rather than alternatives, and this is the largest of the three. The published figure is twelve pounds to the gram, and the exchange pump 3803915 is listed at 5.647 kg, so the two sides agree.

🔌 Function

As a line item it carries the refundable core charge on the exchange; the coolant pump itself drives coolant round the engine's internal circuit, through the block and head and out to the heat exchanger.

⚠️ 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 from the pump's telltale drain, with a crusty trail down the front of the engine
• A rumble or grumble from the pump that changes with engine speed
• Temperature climbing under load, with the top hose hot and the bottom hose barely warm
• Play at the pulley when the shaft is rocked, or an impeller found corroded away on strip-down

🛠️ 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 3803915
• Renew the coolant and the thermostat while the system is drained, and check the drive belt and its tensioner, since a slipping belt makes a sound pump look tired

📦 Condition

• Refundable core deposit - not a physical part
