Power steering (power steering) on Nissan Almera Classic - a node that requires attention over time. The first signs of a malfunction: heavy rotation of the steering wheel, extraneous noise, fluid leaks or jerking when turning. If you ignore these symptoms, you may experience a complete system failure, which will make driving not only uncomfortable, but also dangerous.
In this article we will look at how to replace Power steering on Almera Classic (models B10 And N16) with your own hands, without resorting to expensive car service services. You will learn what tools and spare parts you will need, how to properly drain the old fluid, dismantle the pump and install a new one, and also how to bleed the system to avoid air locks. We will pay special attention to typical mistakes that beginners make and give recommendations on choosing high-quality analogues of original parts.
Symptoms of power steering failure Nissan Almera Classic
Before proceeding with the replacement, it is important to make sure that the problem is in the power steering. Here are the key symptoms that indicate problems:
- 🔧 Heavy steering, especially at low speeds or when parking. If the steering wheel rotates easily when the engine is turned off, but after starting it becomes “stiff,” this is a sign of problems with the power steering pump.
- 💧 Fluid leaks under the hood (red or brown liquid near the pump or rack). Often accompanied by a drop in the level in the tank.
- 🔊 Extraneous sounds: A humming, whistling or grinding noise when turning the steering wheel. This may indicate worn pump bearings or low fluid levels.
- ⚠️ Jerks or dips when the steering wheel rotates, this is a sign of air in the system or wear of the rack.
If you observe any of these signs, it is recommended to get your condition checked power steering fluid (it should be transparent, free of particles and burning smell) and inspect the pump for leaks. In 80% of cases, replacing the pump or rack solves the problem, but sometimes flushing the system and replacing the fluid is sufficient.
⚠️ Attention: If the steering feels heavier after changing the power steering fluid, air may have entered the system. In this case, pumping, rather than replacing the pump, is required.

- Original (not changed yet)
- There was already an analogue (which one?)
- I don't know, haven't checked
- I'm planning to replace it for the first time
Preparing the car for power steering replacement
Before starting work, complete the following steps:
- Install the car onto a level surface and secure the rear wheels with chocks. Raise the front end with a jack (if access to the rack is required).
- Remove the negative terminal from the battery to avoid short circuit.
- Drain the power steering fluid:
- Suck out the liquid from the tank with a syringe.
- Loosen the clamps on the tank hoses and remove them, draining the remainder into a prepared container.
- Turn the steering wheel left and right (with the engine off) to expel fluid from the system.
If you plan to replace only the pump, there is no need to touch the rack. However, if the rack is leaking or jerking is felt, it is recommended to inspect its condition. To do this, you will need to remove the crankcase protection and disconnect the steering rods.
⚠️ Attention: Do not dump power steering fluid on the ground - it is toxic to the environment. Use a tray or container for disposal.
☑️ Preparation for replacing power steering
Step-by-step instructions for replacing the power steering pump
Algorithm for replacing the pump with Nissan Almera Classic:
- Removing the old pump:
- Disconnect the high and low pressure hoses from the pump (you may need to remove the power steering reservoir for convenience).
- Unscrew the 3 bolts securing the pump to the engine block (12 mm wrench).
- Remove the pump, rocking it carefully so as not to damage the splines on the shaft.
- Installing a new pump:
- Transfer the mounting bracket from the old pump to the new one (if it is not included in the kit).
- Reinstall the pump, aligning the shaft splines with the drive. Tighten the fastening bolts to a torque of 20–25 Nm.
- Connect the hoses after lubricating the rubber seals with power steering fluid.
- Belt tension:
- Install the belt onto the pump pulley and tension roller.
- Adjust the tension: the belt deflection between the pulleys should be 8–10 mm when pressed with a force of 10 kg.
If the pump pulley rotates or has play, it is also recommended to replace it. To remove the pulley, use a special puller or carefully knock it down with a hammer through a wooden spacer.
How to check the functionality of the pump after installation?
Start the engine and check:
1. No leaks at hose connections.
2. Are there any extraneous noises during pump operation?
3. Ease of rotation of the steering wheel at idle speed.
If the steering wheel is “stiff”, perhaps air has entered the system - bleeding is required.
Bleeding the power steering system after replacement
After installing a new pump or rack, be sure to bleed the system to remove air. Pumping algorithm:
- Fill the reservoir with fresh power steering fluid to the mark
MAX. - Raise the front of the car with a jack (the wheels should be hanging in the air).
- Turn the steering wheel from lock to lock 10–15 times with the engine off.
- Start the engine and repeat turning the steering wheel, adding fluid to the reservoir (it will drain as the system fills).
- Check for bubbles in the tank. If they are, repeat the procedure.
If the steering wheel remains heavy after bleeding, the following reasons are possible:
- 🔄 Insufficient pumping - repeat the procedure.
- 🔧 Faulty rack - Diagnosis or replacement is required.
- 🛠️ Air leakage through cracks in hoses - Inspect them for damage.
Use only recommended power steering fluid! Mixing different types (eg. Dexron And PSF) can lead to foaming and pump failure.
Typical mistakes when replacing power steering and how to avoid them
Even experienced car owners make mistakes that lead to repeated breakdowns. Here are the most common:
- 🚫 Ignoring the condition of the hoses. Old rubber hoses can crack under pressure, causing fluid to leak. Always inspect them for microcracks.
- 🚫 Incorrect pumping. If you do not remove air from the system, the pump will work under increased load and quickly fail.
- 🚫 Re-tightening of fastening bolts. This may deform the pump housing. Use a torque wrench (tightening torque: 20–25 Nm).
- 🚫 Saving on power steering fluid. Cheap analogues quickly lose their properties, which leads to corrosion of pump parts.
Another common problem is incompatibility of spare parts. For example, a pump from Nissan Primera P12 looks similar to Ulmer's, but has different performance. Always check the article numbers!
If after replacing the power steering pump the steering wheel becomes “lighter” than usual, this is not always good. Too easy rotation may indicate rack wear or low system pressure.
Cost of replacing power steering: comparison of self-repair and service station
Price for replacing power steering Almera Classic varies depending on region and type of spare parts:
| Service/Spare part | On your own | At the service station (with work) |
|---|---|---|
| Power steering pump (original) | 8 000–12 000 ₽ | 15 000–20 000 ₽ |
| Power steering pump (analogue Febi/TRW) | 4 000–6 000 ₽ | 10 000–14 000 ₽ |
| Power steering fluid (1 l) | 500–1 000 ₽ | Included in the cost of work |
| Pump replacement work | — | 3 000–5 000 ₽ |
| Replacing the power steering rack (with pump) | 12 000–18 000 ₽ | 25 000–35 000 ₽ |
As can be seen from the table, self-replacement allows you to save up to 50% of the cost. However, if you do not have experience working with hydraulic systems, it is better to trust the professionals - mistakes when replacing power steering can result in expensive repairs.
FAQ: Frequently asked questions about replacing power steering with Nissan Almera Classic
Is it possible to drive without power steering fluid?
For a short time (for example, to get to a service station) it is possible, but this will greatly wear out the pump and rack. Driving for a long time without fluid will cause the system to jam.
How often should the power steering fluid be changed?
The manufacturer recommends replacement every 60,000 km or every 2 years. If the fluid turns dark or has a burning smell, change it immediately.
What is the difference between the power steering pump for Almera Classic B10 and N16?
On B10 (until 2000) a pump with the article number was installed 48500-4M000, on N16 (after 2000) — 48500-4M010. They are not interchangeable!
Is it possible to replace power steering with electric power steering?
Theoretically it is possible, but it will require a complete rework of the steering system, replacement of the rack and ECU firmware. This is not feasible from an economic point of view.
Why did the steering wheel become heavier after replacing the power steering pump?
Probable reasons:
- Incorrect pump selection (low performance).
- Airing of the system (re-bleeding required).
- Worn rack (needs diagnostics).
