Detailed Description

This Gates Return Line Assembly is engineered for Hyundai steering systems that route fluid from the steering gear to the cooler. Fits 2002-2005 Hyundai XG350, Gear To Cooler, and fits 2001 Hyundai XG300, Gear To Cooler. The 72.5-inch hose length, 16 mm male O-ring end, and 0.375-inch beaded tube end help match the original routing and connection style used on these vehicles. Gates 366387 is a practical replacement choice when servicing a leaking, cracked, or worn power steering return hose on the Hyundai XG350 or Hyundai XG300.

What It Is Used For

  • Replacing a leaking power steering return hose
  • Restoring fluid transfer from the steering gear to the cooler
  • Addressing cracked, hardened, or swollen hose material
  • Correcting seepage at the O-ring or tube connection points
  • Servicing steering noise or fluid loss caused by return-line wear

Installation Notes and Tips

Verify the vehicle year, model, and gear-to-cooler routing before installation. Match the 16 mm male O-ring end and the 0.375-inch beaded tube end to the original connections, and inspect adjacent steering components, clamps, and cooler lines for wear or contamination. Proper routing is important to avoid kinks, abrasion, and premature hose failure.
