# 3801803 Cylinder Head | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured cylinder head from the Engine group, weighing 265.81 kg and listed for 2 applications across the TAD and TWD series, in both cases as the without-VCB head. Volvo Penta supply a reman cylinder head ready for installation with valves and springs fitted, and with the camshaft-bearing housings included where the engine has them. It supersedes part number 3801605, which was also catalogued as a cylinder head. Reman head 3801805 shares the identical published weight, so the supersession, the fitment and the part number are what separate them. In the D16 industrial tables it appears with long block 3801515, injector 3801396 and turbocharger 3801421, and again on the TWD1683VE build with injector 3801907 and turbocharger 3801910. It is supplied on an exchange basis: core deposit 3804803 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

-   3801804 is the sister head at 270.79 kg and supersedes 3801606 instead, so check which old number your engine carries
-   3801805 is listed at exactly the same 265.81 kg with a much wider fitment, so weight cannot be used to choose - order by number
