Description of Change: A drain hose in the turbocharger oil lines group has been improved. Formerly, the hot oil flowing through the drain hose could cause the hose to become hard. This could result in an oil leak. The new drain hose is made from material that resists deterioration caused by high temperatures. The new drain hose will provide increased service life. New heavy duty clamps are required with the new drain hose.
