This part cross-references Gates 361190 for the same application.
Common Problems This Part Can Address
- Power steering fluid leaks at the pressure line
- Hard steering caused by restricted fluid transfer
- Damaged or corroded steering hose tubing
- Incorrect fitment from worn or mismatched steering line components
- Loss of steering assist from a failing pressure hose assembly
Installation Notes and Tips
Verify the end fittings, hose length, and control valve end routing before installation. On 1960-1964 Chevrolet Bel Air and 1960-1964 Chevrolet Impala applications, as well as 1960-1964 Pontiac Laurentian and 1960-1964 Pontiac Parisienne applications, confirm the steering line path matches the original layout and inspect related seals, clamps, and mounting points for wear. Clean the connection points before assembly to help prevent contamination in the power steering system.
