# 3801740 Cylinder Head Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head from the Engine group, weighing 85.28 kg and listed for 8 applications across the D series. It has been replaced by 3801903 and is a use-up item for Rating 5 only, so it should be ordered only where that rating applies and existing stock is being used through. This unit is supplied on an exchange basis: core deposit 3804740 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
