- Noise or stiffness related to restricted fluid flow
- Corrosion-related hose deterioration from road salt and moisture
- Fitment issues from an incorrect or poorly matched replacement hose
Installation Notes and Tips
Verify the end fittings before installation: 18 mm male captive O-ring on one end and 16 mm male inverted flare on the other. Confirm the 59.8 in. hose length and PS switch port location match the original routing on your Acura TL. Inspect adjacent steering components, seals, and mounting points before installing the new hose to help ensure a clean repair.
Quality Assurance
Each Sunsong pressure hose is pressure tested at the factory before shipment to confirm proper operation and installation readiness. The construction is intended to deliver durable service in demanding steering system conditions.
