3806251 Injector Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an injector, from the Fuel System group. It is the refundable charge raised against the old injector when the exchange unit is bought, and it comes back once the worn injector 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 3803251, which is the number to quote for the component itself and the number to check availability against. It carries a published weight of 0.181 kg, which is the mass of the injector itself and is what to plan the return leg around, since nothing goes out against the deposit. No other injector core in this listing of 36 shares its published weight, but the lines are otherwise identical in name and group, so the paired unit number stays the reliable identifier.

⚙️ Key Features

• Core deposit line, not an injector you can fit
• Belongs with the exchange unit, part number 3803251
• Refunded when the old injector is returned
• Published weight 0.181 kg
• Only injector core here at this published weight

🔌 Function

As a line item it carries the refundable core charge on the exchange; the injector itself meters the fuel charge and sprays it into the combustion chamber at the pressure and timing the engine is asking for.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the injector being exchanged
• Rough idle or a misfire on one cylinder that clears when that injector is cut out
• Black or white smoke at the exhaust and fuel consumption climbing
• Hard starting, and the engine hunting or knocking until it warms through
• Fuel found in the engine oil, or leak-off well above the figure the test calls for

🛠️ Service Notes

• The charge is refunded when the worn injector 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 3803251
• Prove the fuel supply, filters and leak-off before condemning an injector, and renew the seat washer and any single-use clamp fixings when the exchange unit goes in

📦 Condition

• Refundable core deposit - not a physical part
