Service bulletins for the 2001 Mazda B-Series

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SA-011-242024-03-06. Service bulletin. STEERING; SERVICE BRAKES, HYDRAULIC; WHEELS; TIRES; ENGINE AND ENGINE COOLING; POWER TRAIN. Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems. Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle-specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers.
01-010-222022-10-06. Service bulletin. POWER TRAIN. Some customers may experience a squeaking noise may be heard from the exhaust manifold when the idle speed drops from fast idle to normal idle speed during cold start. This is caused by a variable valve being stuck in the closed position. When returning from fast idle to normal, the stuck valve suddenly opens due to thermal change around it which causes abnormal noise. To eliminate this concern, the internal design of the exhaust manifold has been modified.

Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems.

05-002-21-38542022-01-06. Service bulletin. POWER TRAIN. Automatic Transmission/Transaxle Cooler and Lines Flushing Procedure: Automatic Transaxle/Transmission (A/T) oil cooler and lines must be power flushed completely before an overhauled or replacement A/T is installed (except SKYACTIV-DRIVE). The most common cause of repeat A/T failures is lack of lubrication to the front and rear planetary gears. This is usually caused by an accumulation of metal particles and debris (from a previous A/T failure) on the internal mesh type baffle of the oil cooler. Power flushing will remove the restriction by back flushing, followed by forward flushing to dislodge a restriction, then back flushing again. This will in turn ensure full ATF flow for the transmission when it is operating.
