Parts for your 2018 Nissan Serena-Power steering fluid

2018 Nissan Serena power-steering fluid: not used on the C27

Power-steering fluid isn’t relevant to the 2018 Nissan Serena (C27). This model uses Electric Power Steering (EPS), so there’s no hydraulic pump, no hoses, and no fluid reservoir to top up or flush. Technical references backing this up include the Nissan Serena C27 Service Manual (Steering System – ST), which outlines a column-assist EPS unit and control module rather than a hydraulic circuit, as well as the C27 Owner’s Manual maintenance schedule, which lists no power-steering fluid item. Brochures and specifications for C27 models (including S-HYBRID and e-POWER variants) also state electric power steering.

Why no fluid? EPS replaces the traditional belt-driven hydraulic pump with an electric motor and an ECU that assists steering based on vehicle speed and driver input. That design removes hydraulic components entirely, so there’s nothing to fill, bleed, or replace. It also reduces parasitic engine load and improves fuel efficiency—handy for a family people mover doing plenty of city kilometres.

• No fluid to maintain: no reservoir, no leaks, no flush intervals.
• Fewer wear points: no pump, pressure lines, or steering fluid seals.
• Efficiency and smoothness: assistance tuned by software for a lighter feel at low speed and firmer feel on the motorway.

Even without fluid, a Serena still benefits from sensible steering-related care during regular servicing. Technicians typically:

• Check for EPS warnings on the dash and scan for control unit fault codes.
• Inspect tie-rod ends, rack boots, and column joints for play or damage.
• Confirm wheel alignment and tyre pressures to keep steering light and even.
• Verify 12V battery health, a weak battery can trigger EPS faults or heavy steering on start-up.
• Apply software updates if Nissan releases EPS calibration improvements.

If the steering ever feels unusually heavy or the EPS light comes on, it’s worth checking the battery first and having the system scanned. And if anyone suggests topping up “power-steering fluid” on a C27 Serena, that’s a red flag—the vehicle simply doesn’t use it.

Popular questions about 2018 Nissan Serena power-steering fluid

Does the 2018 Nissan Serena use power-steering fluid?
No. The C27 Serena is fitted with Electric Power Steering (EPS), so there’s no hydraulic fluid involved. Nissan’s C27 Service Manual (Steering – ST) details a column-assist motor and control unit, and the maintenance schedule in the Owner’s Manual doesn’t list any power-steering fluid service item.

What steering maintenance is needed if there’s no fluid to change?
Focus on the basics: keep the 12V battery healthy, maintain correct tyre pressures, and get wheel alignment checked if the vehicle pulls or the tyres wear unevenly. At service time, have the technician inspect steering joints and boots, scan the EPS for fault codes, and apply any software updates.

What if a workshop says it needs a power-steering fluid top-up?
On a 2018 Serena that’s incorrect—there’s no reservoir to top up. Adding any fluid to the wrong place can cause damage. If advised to add fluid, ask the workshop to point out the reservoir, on a C27 Serena there isn’t one. Seek a second opinion from a Nissan-experienced technician.
