Detailed Description

Built for hydraulic steering systems, this Gates pressure line assembly is intended for the high-pressure side between the pump and the rack or gear box. The hose assembly uses 16 mm end diameters at both connections, with a Swivel O-Ring Type III fitting on one end and a long swivel O-ring on the other to match the specified steering layout. The hose construction exceeds SAE J188 specifications, while the steel tube uses zinc single wall steel and the crimped sleeve uses anti-corrosion steel for added durability in underhood and chassis environments. Gates 365870 is a practical replacement choice for Ford Windstar steering service where the original pressure line has leaked, cracked, or lost hydraulic integrity.

This part cross-references Four Seasons 70033 for the same application.

What It Helps Fix

• Power steering fluid leaks from a damaged pressure hose
• Steering assist loss caused by pressure line failure
• Noise or stiffness from restricted hydraulic flow
• Corrosion or wear at the hose and tube assembly
• Fitment issues when replacing the original Ford Windstar pressure line

Installation Notes and Tips

Confirm the hose routing before removal and compare the end styles, length, and diameter to the original assembly. This pressure line is for the pump-to-rack/gear box position and does not include mounting brackets, bracket bushings, copper washers, rubber mounts, or a switch port. Heat sleeves are included, so verify clearance around exhaust and other hot components during installation. After installation, refill the system with the correct power steering fluid and inspect for leaks with the engine running and the steering cycled lock-to-lock.
