21132385 Belt | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta multi-rib serpentine accessory drive belt weighing 0.247 kg and listed for 29 applications, every one of them an 8.1-litre engine. The accessories catalogue prints it as the drive belt for the 8.1Gi-J and JF, the 8.1GXi-J and JF and the 8.1OSi-J and JF; the earlier 8.1Gi-H and HF, 8.1GXi-G and GF and 8.1OSi-D and DF take belt 21132390 instead, so the letter suffix on the engine plate is what decides. It is the current replacement for 3848939.
