3804118 Turbocharger Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an exchange turbocharger, listed under the Inlet and Exhaust System group. It is the refundable charge held against the worn turbocharger you return rather than a component in its own right. Under Volvo Penta's core numbering it pairs with part 3801118.

⚙️ Key Features

• Refundable core deposit, not a fitted part
• Pairs with part 3801118
• Inlet and Exhaust System group

🔌 Function

Carries the refundable core charge on an exchange turbocharger; the turbocharger it covers uses exhaust energy to drive a compressor, raising the density of the air going into the cylinders.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the turbocharger being exchanged
• Blue smoke and rising oil use with no leak on the outside of the engine
• A rising whine or a metallic rattle as boost comes in
• Poor pull under load with black smoke and low boost
• Play at the shaft, or compressor blades clipped and the housing scored

🛠️ Service Notes

• The deposit is refunded when the old turbocharger is returned; ordering this line on its own supplies no part
• Return the turbocharger with its wheels and housings intact and the ports blanked, since a damaged or dismantled core can reduce or void the refund
• Change the oil and filter and check the feed and drain lines before running the exchange unit, or debris from the old failure will carry straight into it

📦 Condition

• Refundable core deposit - not a physical part
