Installation Notes and Tips
Confirm the vehicle is a 1986-1989 Toyota Celica with the to-gear hose routing before ordering. Match the 16 mm female inverted flare and 16 mm male inverted flare ends to the original connection points, and inspect adjacent seals, brackets, and line routing for wear during service. Properly bleed the power steering system after installation to remove trapped air and verify smooth steering operation.
