Ranger (GM) Ranger B (II)

Power steering fluid capacity & service interval

Ranger (GM) Ranger B (II) uses power steering fluid with a capacity range of 0,3 to 1 liter. Service intervals consist of checks every 10000 km or 6 months. The data covers 9 configurations.

Additional Notes

  • Across the GM Ranger B (II) lineup from 1972-1978, the power steering system is divided into two separate fluid-holding components: the power steering pump/reservoir and the steering box. Each carries its own distinct fluid capacity and, in the case of the steering box, a dedicated service interval.
  • The steering box capacity of 0.3 liter applies uniformly to all variants listed, covering the 1700, 1700S, 1900, 2500, 2500 GTS, and 2800 GTS from 1972-1978. A 0.3-liter figure is characteristic of a recirculating-ball or worm-and-sector steering box, which holds a small, largely static volume of fluid rather than a pressurized circulating supply.
  • The power steering reservoir capacity of 1 liter is specified for the 2500 (1972-1978), 2500 GTS (1972-1974), and 2800 GTS (1974-1978). A 1-liter reservoir capacity is typical of a hydraulic assist system where fluid is actively circulated by a belt-driven pump, requiring a larger working volume than a passive steering box.
  • The 1700, 1700S, and 1900 variants carry only a steering box entry with no separate power steering reservoir specification, while the 2500, 2500 GTS, and 2800 GTS each carry both a steering box entry and a power steering reservoir entry. This reflects a difference in the steering system architecture between the smaller-displacement and larger-displacement variants.
  • The steering box check interval is set at 10,000 km or 6 months under normal use conditions, whichever comes first. The dual-trigger format, combining a distance threshold with a time threshold, accounts for vehicles that accumulate low mileage over a given period, ensuring fluid condition is still evaluated on a calendar basis.
  • No check interval is listed for the 1-liter power steering reservoir on the 2500, 2500 GTS, or 2800 GTS. The steering box and the power steering reservoir therefore operate on different service schedules within the same vehicle.
  • The 2500 GTS was produced from 1972-1974, while the 2800 GTS covered 1974-1978. Both share identical fluid capacities for both the steering box (0.3 liter) and the power steering reservoir (1 liter), despite the engine displacement difference between the two variants.
