🔌 Function

Cools the compressed charge air leaving the turbocharger before it enters the engine, raising its density and lowering combustion temperatures.

⚠️ Common Signs of Failure

• Loss of power and black smoke as charge air flow falls
• Charge air temperature running high
• Water or coolant in the charge air pipework or the inlet
• External corrosion, weeping or salt trails on the cooler body
• Oil pooling in the cooler from a turbocharger passing oil

🛠️ Service Notes

• Pressure test the cooler before fitting anything else, and clear the charge air pipework of oil or water carried over from the old one
• Renew all the joint gaskets and O-rings disturbed on removal, and check the sacrificial anode
• At 34 kg this is a two-person lift and needs freight rather than normal parcel carriage
