3804248 Longblock Engine Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an exchange longblock, listed under the Engine group at 682 kg. The line carries the refundable charge on the worn longblock returned at the end of the exchange and ships nothing itself. Under Volvo Penta's core numbering it pairs with part 3801248. Core 3804247 is listed at 690 kg, 8 kg away, so the published weights do not separate the pair and the exchange longblock number must decide.

⚙️ Key Features

• Refundable core deposit, not a fitted part
• Pairs with part 3801248
• 682 kg
• Only 8 kg from core 3804247, so order by number

🔌 Function

Carries the refundable core charge on an exchange longblock; the longblock it covers is the block, crank, pistons, heads and valve gear that make up the running engine less its ancillaries.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the longblock being exchanged
• Smoke that will not clear once warm, with oil use climbing
• Coolant disappearing with no external leak, or bubbles in the header tank
• Low oil pressure hot and a rumble that follows the load
• Poor compression across several cylinders and worn bores at strip

🛠️ Service Notes

• The deposit is refunded when the old longblock is returned; ordering this line on its own supplies no part
• Return the longblock drained and complete, with heads and valve gear in place, since a stripped core can reduce or void the refund
• Confirm the line against 3804247 before ordering, since the two are 8 kg apart on paper

📦 Condition

• Refundable core deposit - not a physical part
