Important Notes
- Some external components such as the C-clip, pressure switch, harness, and spring have been discontinued and are NOT included.
- This power steering pump uses a housing-supported structure instead of a bearing.
If seizure occurs between the shaft and the housing, both the shaft and the housing would need to be replaced.
However, the housing is supplied as a single unit with the case, and this part has been discontinued.
- Pre-coated bolts (MEK-processed type)
On the Subaru Impreza, the power steering pump bracket is secured using pre-coated bolts (MEK-processed type) due to the high vibration and load in this area.
These bolts feature a special treatment in which adhesive components are micro-encapsulated on the threads. When the bolt is tightened, the microcapsules break, releasing the adhesive, which then begins to cure. This ensures a secure fastening, helping to prevent loosening caused by vibration.
While reused bolts can be cleaned and secured with a thread-locking compound, using genuine pre-coated bolts, when available, is generally preferred for long-term reliability.
What Is Not Included
- Hard parts such as vanes and cam rings are not included, as they are normally replaced only when damaged.
- If you do not plan to replace the reservoir hose at the same time, please consider the Impreza GC8 Power Steering Pump Repair Kit for 34411FA220.
