In addition to the cooling provided by the engine lubrication system, the turbocharger also requires a supply from the engine coolant system to assist with the cooling due to the high loads on the turbocharger. A pipe connection from the engine routes engine coolant through the body of the turbocharger bearing housing. Once the coolant has passed through the bearing housing it is returned to the cooling system.
