Changing the oil in the power steering (gur)

home / Oil

It is difficult to imagine a modern car without power steering. This relatively simple hydraulic system provides the driver with the comfort of driving a vehicle weighing several tons, allowing you to maneuver in tight parking lots of megacities and, at the same time, feel a sufficient load on the steering wheel on highways.

Power steering failure may be less critical than engine or transmission problems, but a sudden power steering failure in heavy traffic or at high speed can be extremely dangerous. An uninformative steering wheel with distorted feedback creates significant difficulties for the driver.

Consider the main reasons why the hydraulic booster can fail.

  • When parking or otherwise maneuvering in a confined space, the driver applies excessive force, trying to increase the angle of rotation of the wheel, which rests on the obstacle. In this situation power steering pump overloaded and, as a result, its fuses “fly”.
  • When entering a turn, the driver at high speeds holds the steering wheel in the extreme position for a long time. This driving style creates increased oil pressure in the system. In this case suffer hydraulic hoses and seals. It is possible not only to accelerate their wear, but also an instant break.
  • The driver ignores a "small" oil leak from the system and / or does not monitor its level during daily operation. When the critical oil level is reached, hydraulic system pump fails after a few minutes.
  • The car owner operates the car with damaged leaky anthers. In this case, small foreign particles gradually clog the system, accelerating the wear of all elements.

Changing the oil in the hydraulic booster is mentioned by car owners much less frequently than in the engine or gearbox. Even vehicle manuals offered by automakers sometimes omit this point. Meanwhile, timely oil change no less important than replacing other vehicle fluids.

There are several fairly simple guidelines by which you can determine optimum replacement time oil in the power steering. Of the empirical signs, these are, first of all, color and smell. Even a car owner with little experience will pay attention to the unpleasant smell of used oil and its significant darkening. It is even easier and more reliable to focus on the mileage or duration of the car. As a rule, the masters of service centers recognize the optimal oil change in the hydraulic booster every 30,000 km or once a year and a half (depending on the intensity of use of the car). Of course, at the same time as changing the oil in the gur, the filters are also replaced.

Self-changing oil in the power steering.

As a rule, they independently perform only a partial oil change in the power steering, those. topping up when there was a leak in the system and you need to stretch the time until a full service. However, a car enthusiast with car maintenance experience can make a replacement on their own.

Changing the oil in the hydraulic booster can be divided into several stages:

  • Assessment of the actual oil level and its condition (color and smell). At this stage, the owner decides or about topping up fresh oil to the actual, or on the need complete replacement oils. When any doubt it is advisable to contact qualified specialists. A significant reduction in the oil level in a short period of time is an absolute reason to turn to professionals for a comprehensive assessment of the condition of the hydraulic booster.
  • In the case of a complete replacement - draining the used oil (we will consider the nuances of partial topping up later)
  • Direct oil change in gur — filling the tank with fresh oil.

Instructions for a complete oil change in gur.

A complete oil change in the hydraulic booster should be carried out with the maximum removal of used oil. In "garage" conditions without special equipment, this is done on a car with "hung" wheels(for free wheeling) in several stages:

1. Remove the cap or plug from the power steering reservoir and use a large syringe to remove the bulk of the oil from the reservoir.

2. Dismantle the tank by disconnecting all clamps and hoses (be careful, a significant amount of oil remains in them) and rinse the container.

3. Direct the free steering rack hose (“return line”, not to be confused with the pump hose) into a bottle with a neck of a suitable diameter and, intensively rotating the steering wheel in a large amplitude, drain the remaining oil.


Oil filling is carried out through a hose leading to the power steering pump, if necessary using a funnel. After the first filling of the container, the system must "pump" by moving the steering wheel to distribute part of the oil through the hoses, and top up.

Partial oil change in gur.

Partial oil change in the power steering is done in a similar way, but here the choice of oil is especially important"for topping up". Ideally, use something similar to the one previously uploaded if you have information about it. Otherwise, mixing of different types of oils is inevitable, which in some cases can have critical consequences for the hydraulic booster.

As a rule, a partial (and, ideally, short-term, before a service visit) oil change in power steering is acceptable. transmission. You can also partly focus on base oil color. Recently, manufacturers have begun to stick to "their" colors when producing power steering oils and, in the absence of another option, the color can be used as a guide. If possible, it is advisable to add liquid of a color similar to that filled in. But, in especially difficult situations, it is permissible to mix yellow oil (as a rule, this is the Mersedes concern) with red (Dexron), but not with green (Volkswagen).

When choosing between mixing two different power steering oils and a combination of "power steering oil with transmission", it makes sense to choose second option.

How to choose power steering oil

Both with a full and partial replacement, you should strictly adhere to the manufacturer's recommendations for the type of oil: synthetic or mineral. If for a motor replacing mineral oil with synthetics rather works as a plus, then replacing oil in a power steering designed for “mineral water” can be synthetic disastrous. This is primarily due to the presence of rubber parts in the hydraulic booster that are absent in the motor. As a rule, additives from synthetic oil are not designed for the neighborhood of rubber and quickly destroy.

It should be remembered that partial topping up of oil in critical situations (for example, in the event of a sudden oil leak from the system), allows you to postpone a visit to a service station only for a short time. If such a problem occurs, an assessment of the causes and troubleshooting should be carried out as fast as possible.

Timely oil change in gur is a fairly simple, but absolutely necessary procedure. By performing a scheduled replacement in a car service, you save time and guarantee your car a really high-quality service. A qualified assessment of the condition of the oil in the hydraulic booster allows you to prevent many malfunctions or eliminate them at an early stage, when external manifestations are minimal.

Changing the oil in a robot or variator will avoid premature wear of the gearbox, extend its service life, improve driving comfort and avoid accidents. The main thing is to trust the work to professionals - HUNDRED SPOT. See for yourself - give us a call
