PAZ 4234

Power steering fluid capacity & service interval

PAZ 4234 requires power steering fluid with a capacity of 4,45 liters. Service intervals occur every 200000 km or 36 months. The data covers 3 configurations.

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

Additional Notes

  • Across all three configurations of the PAZ 4234, the power steering system holds 4.45 liters, a figure that represents the service fill volume for the steering circuit.
  • The 4234-04, 423402-04, and 42303-04 variants fitted with the YAMZ 5342 engine under Euro 4 standards and introduced in 2013-2014 share an identical fluid capacity and change interval with the same body of variants carrying a 2015 start date.
  • The 4234-05, 423402-05, and 42303-05 configurations introduced from 2014 onward also carry the same 4.45-liter capacity, placing all listed variants on a uniform fill specification regardless of sub-model designation.
  • The fluid change interval across all listed configurations is set at 200,000 km or 36 months under normal use conditions, whichever comes first, meaning both a distance threshold and a time limit govern the replacement schedule simultaneously.
  • A 36-month interval tied to 200,000 km reflects a relatively long service cycle, consistent with the demands of a commercial bus platform where steering system reliability over extended mileage is a primary consideration.
