When working on power steering systems, knowing the correct line wrench sizes is crucial for effectively removing and replacing hoses. This information is particularly valuable for DIY mechanics and automotive enthusiasts looking to maintain or repair their vehicles.

Understanding Power Steering Hose Connections

Power steering hoses typically connect the power steering pump to the steering gear or rack. The fittings on these hoses can vary in size depending on the vehicle make and model.

Common Sizes:
  • 18mm: Frequently used for the connection at the steering rack or gearbox.
  • 16mm: Often required for the connection at the power steering pump.
  • 5/8 inch: Sometimes used as an alternative size, particularly in older models or specific brands.

These sizes indicate that having a set of metric line wrenches is essential for effective maintenance.

Choosing the Right Wrench

Using the correct type of wrench is vital to avoid damaging the fittings. A flare nut wrench is recommended because it provides a better grip and minimizes the risk of rounding off the nut corners.

Recommended Tools

  • Flare Nut Wrench: Ideal for both 16mm and 18mm fittings.
  • Crowfoot Wrench: Useful if space is limited; however, these are less common in specific sizes like 16mm.
  • Standard Wrenches: Can be used, but they may not fit as securely as flare nut wrenches.
