Bulletin Summary

Instances of coolant leakage have been observed from the EGR bypass hose during maintenance. These issues are typically caused by improper assembly rather than defects in the parts themselves. The pipe includes a brazed R-section (see photo on bottom right). If the hose is installed by pressing it against this R-section, the clamp can shift upward, reducing clamping force and potentially leading to a coolant leak. This Service Alert outlines the correct procedure for assembling the EGR bypass hose and the inspection steps to follow when a coolant leak is detected.

About Technical Service Bulletins

A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
