## ⚙️ Key Features

-   Genuine Volvo Penta OEM hose assembly
-   OEM part number 20551139
-   Technical distinction: Pre-formed hose assembly with matched end connections for the specified engine circuit

## 🔌 Function

Routes the specified fluid or pressure signal between matched components without leakage, restriction, vibration damage or incorrect connection geometry. Install without twist or preload, renew the specified seals/clamps, preserve the original routing and pressure- or leak-test the circuit after assembly.

## ⚠️ Common Signs of Failure

-   Visible fluid leakage, dampness or staining along the line or connection
-   Cracking, chafing, corrosion or impact damage
-   Restricted flow caused by deposits, deformation or internal collapse
-   Vibration fretting or failed support at clamps and mounting points

## 🛠️ Service Notes

-   Fit the assembly along its original run so the moulded bends and fixed ends sit naturally; forcing a hose to twist or bend tightly to reach it kinks the wall and shortens its life
-   Push each end fully home over the stub so the clip lands behind the bead or in its groove, and fit new clips rather than reusing tired or distorted ones
-   Tighten clips evenly and only enough to seal — over-tightening cuts into the hose wall and starts the next leak
-   Support the assembly with its original clips and stand-offs, clear of the exhaust, belts and sharp edges, and check nothing rubs when the engine moves on its mounts
-   Bring the engine up to temperature, then recheck the joints and clip tightness once the hose has been hot and pressurised
