## 🔌 Function

Cools the compressed air leaving the turbocharger before it enters the cylinders, raising charge density and lowering combustion temperature.

## ⚠️ Common Signs of Failure

-   Power falling away and exhaust smoke increasing under load
-   Boost lost through a cracked core or a weeping end tank
-   Oil found standing in the cooler or its pipework
-   Fins choked, bent or corroded so air cannot pass
-   Split tube or seam revealed on a pressure test

## 🛠️ Service Notes

-   At over 20 kg support the cooler during removal and fitting rather than taking its weight on the pipework
-   Coolers 24078945 and 24078946 also cover D series engines at lower weights, so order by part number
-   Trace the source of any oil in the cooler before the replacement goes on
