Installation Notes and Tips
Verify the vehicle application before installation, especially for 1997 Oldsmobile Cutlass Supreme models with w/o Variable Assist. Confirm the end fitting sizes and routing match the original hose before removal. Inspect mating seals, hard lines, and nearby components for wear or contamination so the replacement can be installed cleanly and sealed correctly.
Quality Assurance
Each Sunsong pressure hose is pressure tested at the factory before release. The assembly is engineered to exceed original equipment performance standards for pressure, burst strength, and tensile durability.
