Parts for your 2013 Toyota Hilux-Power steering pump

2013 Toyota Hilux Power Steering Pump

Yes, the 2013 Toyota Hilux runs a hydraulic power-steering pump. Technical sources back this up: the Toyota Hilux N70 Repair Manual (2005–2015) describes a hydraulic system with a belt-driven, vane-type pump, and the Toyota Electronic Parts Catalogue for 2013 KUN26R/GGN25 lists a “Pump Assy, Power Steering (Vane)” (e.g., 44310-0K020), confirming it’s a fitted component rather than an electric unit.

On this Hilux, the power-steering pump’s job is simple but vital: it pressurises fluid and feeds the steering gear so the wheel stays light and predictable, whether it’s edging a trailer down the driveway or crawling over ruts out the back of beyond. The pump is driven by the accessory belt under the bonnet and circulates ATF-based power-steering fluid through the system to assist steering effort and keep things smooth and quiet.

While the pump itself isn’t a scheduled replacement item, it does appreciate a bit of love at service time. A quick check for leaks around the pump body, high-pressure hose and the shaft seal, plus a look at the pulley and belt condition, goes a long way. Fluid should be at the correct mark and clean, dark, burnt-smelling or glittery fluid points to wear or contamination. Most N70 Hilux models specify ATF Dexron III in the power-steering system, though the cap and owner’s manual are the final word.

If the ute starts to whine on full lock, the steering feels heavy or notchy, or there’s foam in the reservoir, the pump may be starving for fluid, drawing air, or wearing out. Addressing small leaks, replacing a tired belt, and bleeding the system properly often restores quiet operation.

• When replacing the pump, use new O-rings/seals, flush the lines and reservoir, and refill with the correct ATF.
• Bleed by turning the front wheels off the ground from lock to lock with the engine off, then repeat with the engine running, topping up as bubbles clear.
• Inspect the belt for glazing or cracks and set the correct tension after refit.

Many Aussie and Kiwi workshops recommend refreshing the fluid every 60,000–100,000 km in hard-working Hiluxes, especially those that tow, see corrugations, or run bigger tyres. Keeping the pump clean, quiet and leak-free helps the steering box last and preserves that easy, confident feel at the wheel.

Popular questions about 2013 Toyota Hilux power-steering pumps

What fluid does the 2013 Hilux power steering use?
Most N70-series Hilux models use ATF Dexron III in the hydraulic power-steering system. Always double-check the reservoir cap and the owner’s manual for the exact spec, as regional variants can differ slightly. Using the correct fluid helps prevent noise, seal swell and premature pump wear.

How can someone tell if the pump is failing?
Common signs include a whining or groaning noise that rises with engine speed, heavier-than-usual steering, aerated (foamy) fluid, metal flakes in the reservoir, or fluid leaks around the pump or hoses. A slipping or cracked belt can mimic pump failure, so that should be checked first.

Does the power-steering fluid need regular replacement?
Toyota typically calls for inspection rather than a fixed-change interval. However, many local workshops recommend a fluid refresh every 60,000–100,000 km, or sooner if the fluid is dark or smells burnt. Fresh fluid keeps the pump and steering gear happier, especially on utes that tow or work off-road.
