Installation Notes and Tips

Verify the vehicle year, make, and model before installation. This assembly uses various end fitting types and a 165-inch hose length, so matching the original routing and bracket locations is important for proper fit. Inspect surrounding steering components, grommets, bushings, heat shields, and protective sleeves during service and replace worn items as needed to restore the system to original condition.
