Parts for your 2013 Mazda Axela-Power steering fluid

2013 Mazda Axela power-steering fluid – does it apply?

Whether power‑steering fluid is relevant on a 2013 Mazda Axela depends on which series it is. Early 2013 Axela (BL series) uses Electro‑Hydraulic Power Assist Steering (EHPAS), which does require power‑steering fluid. Late‑2013 changeover to the BM series introduced full Electric Power Steering (EPS), which has no hydraulic circuit and therefore uses no fluid.

Technical references: Mazda3 (BL) Workshop Manual – Steering/EHPAS and “Power Steering Fluid Inspection/Replacement” procedures specify use of ATF‑type fluid in the hydraulic system. Mazda3 (BM) Workshop Manual – Electric Power Steering (EPS) section details a motor‑driven rack with no hydraulic pump, lines or reservoir, and no fluid service. Mazda Owner’s Manuals for BL list checks for power‑steering fluid, BM manuals omit any fluid maintenance because EPS is fitted.

• BL‑series (to mid‑2013 build): EHPAS with a fluid reservoir – fluid required.
• BM‑series (from late‑2013 build): EPS – no power‑steering fluid used.

Why some 2013 Axelas don’t use fluid: the BM’s EPS replaces the hydraulic pump and hoses with an electric motor on the steering rack, trimming weight and parasitic losses while removing fluid, leaks and flushes from servicing. That’s why there’s no reservoir to top up on BM cars.

For BL‑series 2013 Axela models with EHPAS (fluid‑equipped): Power‑steering fluid does the heavy lifting in the EHPAS system. It transmits the assist force from the electric pump to the steering rack, cushions components, and carries away heat. Fresh, correct‑spec fluid helps keep the pump quiet, the steering feel consistent, and the rack seals happy over the long haul.

Servicing is straightforward and worth folding into regular maintenance. At each service (roughly every 10,000–15,000 km), have the fluid level and condition checked. The reservoir is typically marked with HOT and COLD levels, level should sit between the marks and the fluid should be clean and translucent red. If it’s gone dark, smells burnt, or there’s foam, it’s time to act. Mazda’s BL workshop literature calls for ATF‑type fluid (Mazda Genuine ATF M‑III or equivalent Dexron III), always match what’s printed on your reservoir cap.

There’s usually no fixed replacement interval in the owner’s schedule, but many techs recommend a full exchange every 80,000–100,000 km or 5–7 years in Aussie and Kiwi conditions, sooner if the car tows, sees lots of city heat, or the pump’s been noisy. Top‑ups alone won’t refresh old fluid, a proper exchange purges the rack and lines. After any fluid work, the system should be bled by turning the wheel lock‑to‑lock with the front wheels off the ground and the engine idling, watching for bubbles and stabilising the level.

Keep an eye out for damp hoses, seeping rack boots, or a red puddle under the nose – they signal leaks that can quickly take out a pump. Catching that early, using the right fluid, and keeping it clean will keep the BL’s steering light, quiet and confidence‑inspiring.

FAQs

How can someone tell which steering system their 2013 Axela has?
Pop the bonnet and look near the left front inner guard for a small plastic reservoir labelled power steering/ATF. If it’s there, it’s the BL with EHPAS (uses fluid). If there’s no reservoir and the owner’s manual doesn’t list power‑steering fluid checks, it’s the BM with EPS (no fluid). Build plate dates around late 2013 often mark the changeover.

What fluid type should be used in a BL‑series Axela?
Mazda specifies an ATF‑type power‑steering fluid for BL EHPAS systems: Mazda Genuine ATF M‑III or an equivalent Dexron III. Always confirm the exact spec on the reservoir cap or in the BL owner’s manual/workshop manual before buying. Don’t mix fluids, if unsure, have a shop perform a full exchange.

Is there a set interval to replace power‑steering fluid?
There’s typically no fixed interval in the BL maintenance schedule, but checking every service is smart. In local conditions, a preventative full exchange every 80,000–100,000 km (or 5–7 years) helps keep the pump and rack happy, especially if the car sees heavy urban use. The BM EPS system doesn’t use fluid and needs no fluid service.
