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

2. 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. Supply from the block & return to cylinder head.
The new design has swivel connector at one end and quick disconnects on the other.PA12 hose would be used which will attach to both the connector ends
Implementation Strategy and Date:
Take a new option & obsolete the existing options
Implement by: End of this year: 31-Dec-2017

3. Feedback Requested – CC9323
Existing CC 9323 (Highlighted in Yellow)
Are there any issues with the proposed plumbing design?
