Peugeot Boxer

Power steering fluid capacity & service interval

Peugeot Boxer uses power steering fluid with a capacity of 1,5 liters. Service intervals include normal use. The data covers 6 configurations.

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

All six Peugeot Boxer configurations listed across the 2011-2024 period share a uniform power steering fluid capacity of 1.5 liters, applying to both the older HDi and the newer BlueHDi engine families.
A 1.5-liter capacity is typical for a hydraulic power steering reservoir fill on a light commercial vehicle of the Boxer's class, representing the total system volume including the reservoir, pump, and steering rack lines.
The three BlueHDi variants — the 120 (4HA), 140 (4HB), and 165 (4HH) — cover the 2019-2024 model years and all carry the same 1.5-liter specification, indicating no capacity difference between the lower and higher output versions of the BlueHDi engine range.
The older HDi lineup includes the 110 (4HG), 130 (4HH), and 150 (4HJ) engine codes, spanning 2011-2020 and 2011-2017 respectively, and each also specifies 1.5 liters, showing continuity in power steering system design across the generation transition from HDi to BlueHDi.
The 4HH engine code appears in both the HDi 130 (2011-2017) and the BlueHDi 165 (2019-2024) designations, yet both share the same 1.5-liter power steering fluid capacity despite representing different engine generations under the same internal code.
All capacity figures are listed under normal use conditions, meaning the 1.5-liter value applies to standard operating environments rather than severe-duty cycles such as frequent towing, extreme temperatures, or high-load commercial operation.
