857051 Hose | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta hose of the late type, from the Cooling System group, weighing 0.406 kg and listed for 26 applications across the BB, DP, SP, MS and SHIELD groups. It supersedes 856268, which was catalogued earlier as a coolant pipe - so the change from a rigid pipe to a hose is the practical point, and the routing may not be identical. Cooling hose 856262 carries the same 26 applications at 0.46 kg.

🚤 Compatibility

• Engine Family: BB, DP, SP, MS, S
