- Summary
- 46310 - Service Update Bulletin. The incorrect upper radiator hose may have been installed during assembly between vehicles equipped with LGX Engines and LGW Engines. Both of these engines have unique upper radiator hoses, and interchanging them may create hose interference with the Air Box, eventually resulting in a coolant leak.
