🔌 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
