Installation Notes and Tips

Verify vehicle configuration before ordering: this assembly fits the 2001-2003 Toyota Highlander, w/o Oil Cooler. Compare the original hose routing, bracket locations, and fitting styles to confirm a direct match. Inspect surrounding steering components and replace any damaged seals or mounting points during service to help prevent repeat leaks. Part number 3401191 should be matched to the OE-style application before installation.

Quality Assurance

Each pressure hose is high-pressure tested at the factory before shipment. The assembly is engineered to meet or exceed original equipment performance targets for pressure, burst resistance, and tensile strength, supporting reliable operation after installation.
