3801942 Longblock | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta longblock from the Engine group, weighing 272.16 kg and listed for 12 applications in the V series, marked ECM REPROGRAMMING REQUIRED with the Volvo Penta longblock guidelines to be followed. Longblock 3801901 is within a kilo of this one on published weight and covers the same series, so the application list and the part number are the only reliable guide. This unit is supplied on an exchange basis: core deposit 3804942 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

• Bottom-end knock or heavy blow-by
• Bearing material in the oil filter or sump
• Rising oil or coolant consumption with no external leak
• Damage found after an overheat or loss of oil pressure

🛠️ Service Notes

• Budget for the control module reprogramming - the engine will not run correctly without it
• Longblocks 3801901 and 3801943 sit within a few kilos of this one; order by engine application, not by weight
• Renew or clean the oil cooler, filters and pipework so debris from the old failure cannot reach the new bearings
• Core deposit 3804942 is charged with this unit and refunded when the old one is returned - order both together
