## ⚙️ Key Features

-   Heat exchanger for D6-400 to D6-480 engines
-   Coolant to raw-water construction
-   38.56 kg
-   Listed for 18 D series applications
-   Supersedes part number 22437234
-   The engine range is the selection detail

## 🔌 Function

Transfers heat from the engine coolant into the raw seawater flowing through its core, so the coolant returns to the engine at working temperature and the heat goes overboard.

## ⚠️ Common Signs of Failure

-   Engine temperature climbing under load and settling again at low power
-   Coolant loss with no external leak, or oil traces showing in the coolant
-   Salt crust or weeping at the end covers
-   Seawater side blocked with weed, scale or impeller debris
-   Tube stack found furred, split or corroded through when drawn

## 🛠️ Service Notes

-   At nearly 39 kg this needs proper support and lifting arranged before removal
-   Check the seawater pump impeller, strainer and anodes before condemning the exchanger for a running-hot complaint, as restricted seawater flow looks identical
-   Renew the end cover seals and o-rings whenever the core is disturbed
