The Volkswagen Passat B3 suspension belt pulley has to be replaced very rarely, but the power steering suspension belt and pumps need to be changed a little more often. An accidental break of this belt will not cause immediate harm, but it is also impossible to drive without it, because this mounted belt drives the water pump that circulates coolant in the system. Therefore, every 30 thousand it is necessary to check the belt of attached units (generator, power steering, pump). If you need to replace the power steering belt on a Passat B3, then this video instruction will be useful.
Such work must be carried out from under the car, so an inspection hole or overpass is indispensable. You will need to unscrew several bolts and loosen the tension on the power steering belt and pump in order to remove it.
Is it possible to change the power steering belt yourself and how to do it?
Replacement can be done at a car repair shop or yourself. The only difficulty is that the power steering belt is located behind the alternator belt, so replacing it involves removing both belts, which subsequently entails the need to properly tension them. This cannot be done without knowledge and a certain skill.
In order to remove the belt we are interested in, it is necessary to first loosen the bolts securing the power steering pump. And only then, by rotating the adjusting bolt, the tension of the belt itself is released, after which it is directly removed from the male parts.
The new belt is installed in the reverse order of removal. It should be remembered that it is mounted on the pulleys of the power steering pump, the air conditioning compressor, and also on the crankshaft pulley. The final step is tension adjustment, to which the greatest attention should be paid.
Drive Element Replacement Procedure
You can learn how to change the power steering belt from the step-by-step instructions.
- We lift the vehicle on a lift, or place it over a hole to get to the rack.
- You need to disconnect the battery from the vehicle's electrical system (disconnect the terminals).
- Remove the engine protection, if equipped. Depending on the brand of the car, we use a screwdriver or wrench.
- If necessary, first remove the alternator belt. In some brands of cars, without this procedure you will not be able to get to the power steering drive belt.
- Find the steering rack pump. In most brands of cars, it is located on the driver's side.
- Find the tensioner pulley. Its top and bottom bolts will most likely be tightly seated due to rust, so you can douse them with WD-40. After a while, loosen the bolts.
- We loosen both bolts of the pulley so that it begins to move freely.
- When the pulley and tension roller are relaxed, the belt should come off easily.
How to loosen the tension on the power steering belt
New belts are often quite tight, making it sometimes difficult to put on. To make this task easier, move the pump towards the engine until it stops. If this measure does not help, then the belt is put on by turning the pump or crankshaft by hand until the process of putting on the belt is complete.
If your car has not reached the required mileage for replacement yet, but you have doubts about the reliability of the belt, it is worth making a diagnosis. You can also pre-tighten the belt - this in some cases will help lead to the disappearance of extraneous noise.
On a Volkswagen Passat B3, drivers often have to change the suspension belt pulley, but the power steering belt and pump are replaced quite often. Car enthusiasts should be prepared to carry out repairs, which can be done independently or contact a car service center. To avoid problems when servicing the machine, it is recommended that you read the instructions provided.
Is it possible to drive without a power steering belt?
The auto parts store promised to bring me the tank in a day. To prevent the working fluid from leaking out, I removed the belt. As a result, I had to choose: park the car until the repairs are completed or continue driving it. My car uses an individual GRU pump drive.
Since the operation of other units does not depend on the power steering, it was decided to continue operating the machine. After 2 days of such use, no problems were identified. However, more effort was required when turning the steering wheel. If the belt were a bypass belt and used to transmit power to another device, then I would not operate the car.
Replacement features
Drivers may not notice an accidental break immediately, as the consequences appear over time.
However, replacing the Passat B3 power steering belt must be carried out in a timely manner.
It drives the water pump, which is responsible for circulating coolant in the car system.
The serviceability of parts of mounted units should be checked every 30 thousand kilometers or once every 2 years. Inspection and repairs must be carried out from under the machine, so work is only possible on an overpass or inspection pit. First you need to prepare new spare parts and a set of automotive tools.
Toyota Carina White Bride Logbook Replacing power steering fluid
So I decided to replace the fluid in the power steering, which, as it turned out, was not in vain. We roll the front wheels so that they rotate without load. We clean the power steering pump reservoir from dust and dirt
Open the reservoir cap and see what color the liquid is.
Using a syringe with a piece of hose, we pump out the liquid that is in the reservoir itself from the washer and again wonder what color it is
Remove the return hose from the tank, which goes from the rack to the tank
And we direct it into a pre-prepared bottle 0.5
Turning the wheels left and right, we understand that the liquid is no longer flowing. We fill the tank with new, clean liquid
We hear that something is flowing somewhere, it turns out that we forgot to put a plug in the place of the removed hose
Pour the liquid into the tank again, start the car for 3-5 seconds, turn it off, we see that the tank is filled from the return line, and the tank is empty
We see that the liquid is becoming lighter. Fill and drain, and so on 3 times (that was enough for me), almost clean liquid flowed from the return.
We fill in the remainder and see (and the photo shows) that the liquid in the tank is clean red
We start the car and slowly turn the steering wheel left and right 5-6 times, turn it off, see how there are air bubbles in the tank, add fluid if necessary.
We smoke for 5 minutes and start it again, 5-6 turns of the steering wheel and smoke again, and so on until we see that the air bubbles are gone. As we pour the last portion of liquid, we understand that the result is obvious! This is where all the work ends. Time taken 1-1.5 hours, budget - about 300 rubles,
Replacement process
Replacement is carried out in the following sequence:
- the negative terminal is disconnected;
- the air purifier is dismantled;
- the air conditioner and generator belts are removed, placing direction marks for correct installation;
- the tension is retracted and the tension is released;
- the rod is inserted into the combined holes of the tension and support rollers;
- the latches open and the upper part of the timing drive casing is removed;
- all marks are set and aligned;
- the crankshaft pulley is removed;
- the tensioner is turned counterclockwise and the fastening nut is loosened;
- the timing belt is removed;
- The tension roller is changed.
Belt installation and assembly are carried out in reverse order. It is important to perform this process correctly so that the parts are placed in the right place and perform their functions correctly.
Installing a new belt
Below is an algorithm for how to tighten the power steering belt.
- The power steering belt is tensioned with the teeth inward, it is pulled through all the rollers where the old one was.
- The power steering pump is tensioned and the bolts are tightened. Use a pry bar to move the pump away, applying tension to the belt. Hold the pump with a pry bar and tighten its bolts.
- We install everything that was removed in reverse order: the generator belt and engine protection. We connect the battery.
- We start the car. Let's listen. If there is a whistle or squeal from the engine compartment, it means that the power steering or generator belt is not tensioned enough. If there are no extraneous sounds, we proceed to a 10-15 km race, upon completion of which we need to tighten the belt bolts again tightly, since the long operation of the internal combustion engine after the first race could cause them to become loose.

In this case, the protrusion on the tensioner body should fit into the recess in the socket.
Next, reinstall the power steering pump drive belt.

Friction drive
This generator power steering belt transmits torque through friction. Its magnitude is proportional to the force in the contact zone. This indicator depends on how much pretension is created, as well as on the shape of the pulley or cone with which the element is held or wedged in the pulley.
Regular checks of drive belts
Every car owner should regularly inspect these elements and know how to tension the power steering belt. The check can be carried out with the engine not running. To test, you just need to press your finger on the part - it will become clear whether the tension has weakened or not. During such an inspection, the part should not move even 1-2 cm. Other damage is also checked by touch. If you notice damaged areas on the belt, it needs to be replaced. It is worth noting that when buying a new element, you do not have to purchase the original part. The automotive market offers non-original products that are no worse in technical characteristics and quality, and maybe even better than the original models.
What is a drive belt?
When the designers came to the conclusion that it was necessary to somehow transmit rotation to the auxiliary units, a belt drive was chosen for this. Several reasons played a decisive role in this choice. By means of a belt drive, rotational energy can be transmitted silently and smoothly, while friction losses will be insignificant. Also, torque can be transmitted via a belt to any distance between the axes of the pulleys. Now in some premium car models you can find a chain drive, but in the mass automotive industry nothing better than these parts have yet been invented.

Diagram of the location of the drive of auxiliary units of a car with air conditioning.
1 — auxiliary drive pulley; 2 — generator pulley; 3 - guide roller; 4 - tension roller; 5 — coolant pump pulley; 6 — auxiliary drive belt; 7 - air conditioning compressor pulley
The accessory drive pulley transmits rotation through a belt to the generator, coolant pump and air conditioning compressor pulleys. The guide and tension rollers serve to change the belt routing and ensure proper tension. A pulley of increased width is attached to the coolant pump shaft, driving the power steering pump through a separate belt.
Depending on the vehicle configuration, there are two options for drive schemes for auxiliary units: with air conditioning and without air conditioning.
The work is shown on a car with air conditioning.
We carry out the work on an inspection ditch or overpass.
Useful tips
As you can see, if everything is done correctly, replacing the alternator belt will take no more than 30-40 minutes. Let us remind you once again that installation difficulties may arise on some cars, so you should not neglect sketching the diagram when removing the old belt.
Also, given the large number of different manufacturers on the market, you should not opt for the cheapest products. This is true for both timing belts and alternator belts. In practice, it is optimal to purchase products from well-known companies (for example, Gates belts). It is important to find the original and not a fake.
We also recommend reading the article about which timing belts are best to choose. From this article you will learn which companies and manufacturers of timing belts are trustworthy, as well as what to look for when choosing a timing belt.
After replacing the belt and checking its tension, you should put a load on the generator (turn on the high beams, heater, heating) and let it idle. The appearance of a whistle will indicate that the belt needs to be tightened. However, it also happens that the whistling of the alternator belt occurs for other reasons. In this case, it is necessary to study separate material on this topic.
