Full model list at the end of this description.

## ⚙️ Key Features

-   Genuine Volvo Penta moulded turbocharger cooling hose
-   Designed for the D13B and D13C cooling layout
-   Carries engine coolant to or from the turbocharger circuit
-   Correct bends prevent kinking and contact with hot exhaust components
-   Engine type: Volvo Penta 12.8-litre inline six-cylinder marine diesel

## 🔌 Function

Circulates coolant through the turbocharger cooling connection to control bearing-housing and shutdown temperatures.

## ⚠️ Common Signs of Failure

-   Coolant seepage around the hose or clamps
-   Softening, swelling or surface cracking
-   Coolant odour or unexplained coolant loss
-   Localized overheating around the turbocharger
-   Hose chafing or heat damage near exhaust components

## 🛠️ Service Notes

-   Fit the hose dry onto clean, smooth stubs and push it fully onto the spigot so the clip lands behind the bead; do not use grease or sealant to help it on
-   Keep the original routing and bend radius and use the correct clips, tightened evenly — a hose that is kinked, stretched or pulled to fit will fail early
-   Check the stubs for corrosion, pitting and burrs while the hose is off, and clear any scale or debris out of the system
-   Keep the hose away from hot surfaces and anything that can chafe it, and support long runs as they were originally clipped
-   Refill, vent and run the engine to temperature, then re-check every joint and re-tighten the clips once the hose has bedded in
