SummaryThe coolant vent lines of the low-temperature circuit are designed to remove air bubbles from the system toensure optimal cooling performance. Internal quality inspections have revealed that leaks may occur due tolocalized material aging on the vent lines.

A coolant leak may result and cause a yellow check control message and reduced engine performance.
