ERF EC6

Power steering fluid capacity & service interval

ERF EC6 power steering fluid capacity is 4,7 liters. Service intervals require a check every 16000 km. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
EC 6.22 (4x2/6x2) (1996-2002)
  • Use: Normal
  • Capacity 4,7 liter
  • Check 16000 km
EC 6.23 (4x2/6x2) (1996-2002)
  • Use: Normal
  • Capacity 4,7 liter
  • Check 16000 km

Additional Notes

  • The ERF EC6 power steering system holds 4.7 liters across both the EC 6.22 and EC 6.23 variants, covering 4x2 and 6x2 axle configurations alike.
  • A 4.7-liter capacity in a heavy commercial power steering circuit is consistent with a full hydraulic reservoir and line volume, rather than a simple top-up quantity.
  • The EC 6.22 (4x2/6x2) carries a normal-use check interval of 16,000 km for the power steering fluid.
  • The EC 6.23 (4x2/6x2) shares the same 16,000 km normal-use check interval, placing both variants on an identical service schedule.
  • A check interval, as opposed to a change interval, means the fluid level and condition are inspected at 16,000 km rather than drained and replaced on that cycle.
  • Both the EC 6.22 and EC 6.23 specifications apply to the 1996-2002 production period, with no variation in capacity or interval recorded across those model years.
