OEM installation check with CAD models for ISL/QSL CC option for coolant lines for D phase release – CC9323 Date- 13th Feb 2017

Project Scope Change Summary: Implementation Strategy and Date: The CPR coolant lines on L series engines are being converted from rigid tubes to nylon tubes. The diameter of the supply & return tubes was modified from existing 10.92mm to 14mm to meet the flow requirements of air compressor The basic routing of the lines is same.
