Bulletin Summary
Improper operating coolant surge tank filler cap. We received a number of complaints regarding frequent coolant loss at the overflow line of the coolant surge tank filler cap. Tests have shown that this is due to the installation of a batch of improper operating filler caps. On these filler caps, the pressure relief valve does not close firmly on the filler neck seat, causing unnecessary coolant loss through the overflow line of the filler cap.
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.
