Parts for your 2007 Nissan Maxima-Power steering pump

2007 Nissan Maxima power-steering-pump

Technical references confirm the 2007 Nissan Maxima (A34, VQ35DE) uses a conventional, belt-driven hydraulic power steering pump. This is documented in the Nissan Factory Service Manual (2007 Maxima, Steering “ST” section: Power Steering Oil Pump) and supported by OEM parts catalogues listing a pump assembly (e.g., 49110-7Y000/49110-ZK30A) and associated hoses. Aftermarket drive-belt diagrams for the VQ35DE also show a power-steering pump pulley in the accessory system. So, a power-steering pump is definitely relevant to this model.

On the 2007 Maxima, the power-steering pump’s job is to generate hydraulic pressure that helps turn the wheels with minimal effort, especially at low speeds and when parking. It’s driven by the accessory belt on the VQ35DE, sending pressurised fluid to the steering rack to deliver smooth, predictable assist. When the pump is healthy and the fluid is clean, steering feel stays consistent and quiet.

As part of regular servicing, it’s smart to keep an eye on the fluid level and condition in the reservoir. Fluid that’s dark, smells burnt, or shows metal or rubber debris is a sign it’s time for a change. Many workshops in Australia and New Zealand recommend refreshing power-steering fluid roughly every 60,000–100,000 kilometres, or sooner if it’s contaminated. Use Genuine Nissan Power Steering Fluid or a compatible equivalent specified in the owner’s manual, mixing fluids or using unsuitable ATF can cause noise, seal swell, or premature pump wear.

• Common symptoms of a tired pump include a whining or groaning noise that rises with engine speed, heavy steering effort, shudder at low speeds, or visible leaks from the pump, hoses, or reservoir.
• Check the accessory belt for cracks, glazing, or slack. A slipping or worn belt can mimic pump failure.

If replacement is needed, a quality new or remanufactured pump paired with fresh fluid is the go. The job typically involves draining the system, removing the belt, swapping the pump and any suspect hoses, then bleeding the system to clear air. For bleeding, raise the front wheels, turn lock-to-lock slowly with the engine off, top up fluid, then repeat with the engine running—avoiding holding full lock. After a short drive, recheck for leaks and fluid level. Attending to minor seepage early and keeping the right fluid in the system will help the Maxima’s steering stay light, quiet, and reliable for the long haul.

Does the 2007 Nissan Maxima actually have a power-steering pump?

Yes. The 2007 Maxima uses a hydraulic steering system with a belt-driven pump. This is identified in the Nissan Factory Service Manual (Steering “ST” section) and by OEM parts listings for the pump assembly and associated hoses/pulleys.

What fluid should go in the Maxima’s power steering system?

Use Genuine Nissan Power Steering Fluid or a manufacturer-approved equivalent as specified in the owner’s manual. Avoid mixing fluid types, using the wrong fluid can cause noise, leaks, and premature wear.

When should the power-steering pump be replaced?

Consider replacement if there’s persistent whining, heavy steering, metal-contaminated fluid, or confirmed leakage from the pump shaft or housing. Many pumps last well beyond 150,000 kilometres, but fluid quality, belt condition, and driving environment all play a part.
