3804162 Injector Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an exchange injector, listed under the Fuel System group. It is the refundable charge held against the worn injector you send back, raised as a line on the order rather than as a shipped component. Under Volvo Penta's core numbering it pairs with part 3801162. No weight is published against this line, and none should be assumed from the other injector cores in this group.

⚙️ Key Features

• Refundable core deposit, not a fitted part
• Pairs with part 3801162
• Fuel System group

🔌 Function

Carries the refundable core charge on an exchange injector; the injector it covers atomises metered fuel into the combustion chamber at the correct pressure and spray pattern.

⚠️ 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
• Lumpy idle with a knock or rattle from one cylinder
• Black smoke under load and fuel use rising
• Hard cold starting with white smoke that lingers
• Excess back-leakage on test, or a nozzle dribbling rather than atomising

🛠️ Service Notes

• The deposit is refunded when the old injector is returned; ordering this line on its own supplies no part
• Return the injector with the nozzle capped and protected, since a bent or damaged tip can reduce or void the refund
• Renew the copper seat washer and sealing rings, and check the injector bore for soot and carbon before fitting the exchange unit

📦 Condition

• Refundable core deposit - not a physical part
