Over time, it wears out: a hum appears when turning the steering wheel, fluid leaks or tight rotation. If you ignore these symptoms, you may experience complete system failure or damage to the rack.
In this article we will look at how replace the power steering pump yourself on Teana J32without resorting to the services of a service station. You will learn what tools you will need, how to properly drain the fluid, remove the old pump and install a new one, and how to avoid common mistakes. The material is based on the experience of car owners and craftsmen specializing in Nissan.
Signs of a faulty power steering pump: when replacement is required
The first signs of problems with the pump often go unnoticed until the situation worsens. Pay attention to the following symptoms:
- 🔊 Hum or squeal when turning the steering wheel (especially when cold or at low engine speeds). The sound may increase with increasing load.
- 💧 Power steering fluid leaks under the hood (red or brown fluid near the pump or hoses). Check the level in the tank - if it drops for no apparent reason, this is an alarming sign.
- ⚠️ Stiff steering wheel rotation, especially at low speeds. If the steering wheel becomes “heavy” even after the engine warms up, the pump is not creating enough pressure.
- 🌀 Foam or bubbles in the power steering reservoir. This indicates air leaks through worn seals or cracks in the pump housing.
If you notice at least one of these signs, do not delay diagnosis. In the early stages the problem can be solved pump repair (replacing seals, bearings), but in 80% of cases Teana J32 after 150–200 thousand kilometers it is required complete replacement.
⚠️ Attention: If you ignore the hum of the power steering pump, this will lead to accelerated wear of the rack and steering rods. In a critical situation, the steering wheel may “jam” when turning, which can lead to an accident.
Before replacing, make sure that the problem is with the pump. Sometimes similar symptoms cause:
- 🔧 Clogged filter in the power steering reservoir.
- 🛢️ Low level or poor quality fluid (for example,
ATFinstead of specializedPSF). - 🔄 Worn pump drive belt.
- Every month
- Once every six months
- Only when problems arise
- Never

Step-by-step instructions for replacing the power steering pump
The replacement process takes 3-5 hours depending on experience. Follow the algorithm:
1. Preparing and draining the liquid
Park the car on a level surface and disconnect the negative terminal of the battery. Raise the front end on a jack or use an inspection pit.
Drain power steering fluid:
- Disconnect return hose from the power steering reservoir (lower pipe) and direct it into the container.
- Turn the steering wheel left and right until it stops 5-6 times so that the fluid leaves the system.
- Disconnect supply hose from the pump (upper pipe) and drain the residue.
2. Dismantling the old pump
Remove the accessory drive belt:
- Loosen the tension roller with a 14mm wrench.
- Remove the belt from the pulleys.
Next:
- Unscrew pump pulley (a puller or pry bar will be required). Secure the pulley from turning using a screwdriver through the holes.
- Unscrew the 3 bolts securing the pump to the bracket (12 mm head).
- Carefully remove the pump by disconnecting the electrical connector (if there is a pressure sensor).
How to remove a pulley without a puller?
If you don’t have a puller, use two open-end wrenches: one against the pulley, the other against the fastening bolt. With a sharp movement, pull the pulley off the shaft. Be careful not to damage the thread!
3. Installation of a new pump
Before installation:
- Check condition of the seal on the new pump (it must be lubricated).
- Transfer mounting bracket from the old pump (if it is not included in the kit).
Installation:
- Attach the pump to the bracket and tighten the bolts to torque
25–30 Nm. - Install the pulley and secure with a bolt (torque
40–50 Nm). - Connect the hoses using new clamps. Pay attention to the direction of flow (indicated by arrows on the pump body).
4. Filling the system and bleeding
Fill new power steering fluid through the reservoir to the mark MAX. Bleed the system:
- Turn the steering wheel all the way left and right 10–15 times with the engine off.
- Start the engine and repeat the procedure (the fluid will leak out - top it up).
- Check for air in the system (no foam in the tank) and leaks.
After replacing the pump, for the first 500 km, avoid sharp turns of the steering wheel in place - this will shorten the life of the new unit.
Typical mistakes when replacing a power steering pump and how to avoid them
Even experienced car owners make mistakes that lead to repeated replacement or breakage of the rack. Let's look at the most common ones:
- 🔧 Incorrect pulley tightening. A weak tightening will cause the pulley to rotate on the shaft, a strong tightening will damage the bearing. Use a torque wrench!
- 💧 Refilling with low-quality liquid. Liquid type
DEXRON IIInot suitable for Teana J32 - use onlyNissan PSForATF D-II. - 🌀 Incomplete bleeding of the system. The remaining air will cause foam in the tank and a hum during operation. Pump until the bubbles disappear completely.
- ⚠️ Ignoring the condition of the hoses. Old hoses may burst under the pressure of a new pump. Inspect them for cracks and replace if necessary.
Another common problem is mixed up hoses. On Teana J32 the supply hose (from the tank to the pump) has larger diameterthan the opposite. If they are swapped, the pump will overload and quickly fail.
⚠️ Attention: After replacing the pump, be sure to check the fluid level after 100–200 km. New seals may shrink, leading to leaks.

Preventing power steering pump malfunctions: how to extend its service life
Average power steering pump resource per Nissan Teana J32 - 150–200 thousand km, but with proper care it can be increased to 250–300 thousand km. Follow the recommendations:
- 📅 Change power steering fluid every 60 thousand km or once every 3 years. Over time, it loses its properties and becomes contaminated with wear products.
- 🔍 Check the fluid level once a month. The optimal level is between the marks
MINAndMAXon the tank. - 🚗 Avoid holding the steering wheel in the extreme position for long periods of time (more than 5 seconds). This creates maximum load on the pump.
- 🌀 Monitor the condition of the drive belt. It should be tensioned (deflection no more than 10 mm when pressed), without cracks or delaminations.
Also pay attention to:
- 🌡️ Liquid temperature. If the power steering reservoir is overheating (hot to the touch), check the system for blockages or pump failure.
- 🔊 Extraneous sounds. The appearance of a hum when turning is the first sign of pump bearing wear.
If you often drive off-road or in dusty conditions, install additional filter into the power steering reservoir or change the fluid more often.
