Installation Notes and Tips

Verify vehicle configuration before ordering: this hose fits 2009-2012 Chevrolet Colorado and 2009-2012 GMC Canyon models with Z85 or ZQ8 suspension. Confirm the 12 mm and 16 mm male O-ring ends match the original line, and inspect adjacent seals, brackets, and routing points during service. Proper bleeding of the power steering system after installation helps restore normal steering feel.
