Parts for your 2020 Toyota Hilux-Power steering fluid

2020 Toyota Hilux Power Steering Fluid

Power-steering fluid is fitted and relevant to the 2020 Toyota Hilux. Toyota’s service literature for the AN120/AN130 Hilux generation (2015–2020) and the 2020 Owner’s Manual specify a hydraulic rack-and-pinion system driven by a belt‑driven pump and a fluid reservoir, along with routine checks of power‑steering fluid level and condition. That confirms the ute uses hydraulic assistance rather than electric power steering, so it needs the correct fluid and periodic attention.

On a 2020 Hilux, power‑steering fluid does the heavy lifting. It transmits hydraulic pressure from the pump to the steering rack, making low‑speed manoeuvres easy, protecting internal seals, and lubricating and cooling the pump and valves. Fresh, correct-spec fluid helps the steering feel consistent, quiet and predictable, especially with larger tyres or a load on the tray.

Neglected or incorrect fluid can cause groaning noises, shudder at low speeds, heavier steering, or foamy fluid in the reservoir. Over time, heat and shear can darken the fluid and increase varnish, which isn’t great for the pump or rack seals. Catching that early is cheaper than a new rack.

Use the fluid grade specified in the Hilux Owner’s Manual or on the reservoir cap, many models in this generation specify a Dexron III–type ATF for the power‑steering system. Check the level with the engine off on level ground, using the COLD or HOT marks as directed in the manual. The fluid should be clean and red to light amber, if it’s brown/black, smells burnt, or shows metallic sparkle, plan a change.

• Inspect level and colour at each service (typically every 10,000–15,000 km or 6–12 months in Aus/NZ conditions).
• Top up only with the correct spec, avoid mixing different types. Use a clean funnel and keep dust out.
• Look for leaks at hose crimps, the pump, and rack ends (wetness at the rack boots is a giveaway).
• If fluid is dark or aerated—or steering is noisy—book a fluid exchange. Many workshops recommend 60,000–100,000 km or 4–6 years as a practical interval, unless Toyota specifies otherwise.
• After any steering work, bleed the system properly: wheels off the ground, turn lock‑to‑lock slowly, then run the engine and repeat. Don’t hold it on the stops.
• Check the drive belt that spins the pump, cracks or glazing can cause squeal and poor assist.

A return‑line fluid exchange is usually preferred over harsh “power flushing.” If the steering feels odd after topping up, or the fluid keeps dropping, get a technician to pressure‑test the system—small leaks can become big ones off‑road.

FAQs

Does the 2020 Hilux use power‑steering fluid or electric power steering?
It uses a hydraulic power‑assisted rack with a belt‑driven pump, so yes—power‑steering fluid is required. Toyota’s owner and workshop information for the 2015–2020 AN120/AN130 Hilux outline fluid level checks and a reservoir, confirming it’s not electric assist.

What fluid should go in a 2020 Hilux power steering system?
Use the fluid grade listed in the Owner’s Manual or on the reservoir cap. Many 2020 Hilux models specify a Dexron III–type ATF for the power‑steering system. Stick with Toyota Genuine or a high‑quality equivalent, and don’t mix different fluid types.

How often should the power‑steering fluid be changed?
Toyota often doesn’t set a fixed interval, instead, inspect at every service. In Australian and New Zealand conditions, many workshops recommend a preventative exchange every 60,000–100,000 km or 4–6 years, or sooner if the fluid is dark, burnt, or foamy, or if the steering is noisy.
