Lamps used in the car

Any modern car or truck can be serviced and repaired independently, in a regular garage. All that is required for this is a set of tools and a factory repair manual with a detailed (step-by-step) description of the operations. Such a manual should contain the types of operating fluids, oils and lubricants used, and most importantly, the tightening torques of all threaded connections of parts of vehicle components and assemblies. Italian cars - Fiat Alfa Romeo Lancia Ferrari Mazerati (Maserati) have their own design features. You can also join a special group select all french cars - Peugout (Peugeot), Renault (Renault) and Citroen (Citroen). German cars are complex. This applies especially to Mercedes Benz (Mercedes Benz), BMW (BMW), Audi (Audi) and Porsche (Porsch), in a slightly smaller - to Volkswagen (Volkswagen) and Opel (Opel). The next large group, isolated by design features, is made up of American manufacturers - Chrysler, Jeep, Plymouth, Dodge, Eagle, Chevrolet, GMC, Cadillac, Pontiac, Oldsmobile, Ford, Mercury, Lincoln . Of the Korean firms, it should be noted Hyundai / Kia, GM - DAT (Daewoo), SsangYong.

More recently, Japanese cars have been relatively low original cost And affordable prices for spare parts, but Lately they caught up with the prestigious European brands in these indicators. Moreover, this applies almost equally to all brands of cars from the land of the rising sun - Toyota (Toyota), Mitsubishi (Mitsubishi), Subaru (Subaru), Isuzu (Isuzu), Honda (Honda), Mazda (Mazda or, as they used to say, Matsuda) , Suzuki (Suzuki), Daihatsu (Daihatsu), Nissan (Nissan). Well, and the cars produced under the Japanese-American brands Lexus (Lexus), Scion (Scyon), Infinity (Infiniti),

First of all, we purchase synthetic fluid for power steering systems, this is especially true for the northern regions with their harsh climate. The fluid must meet the specifications of "ATF DEXRON III".

1. Open the lid of the power steering reservoir, remove the mesh, pump out the old liquid (into an unnecessary container) with a medical syringe of 150 cubes.

2. Using pliers, remove the old clamps from the tank nozzles. We remove and wash the tank.

3. Next, install the washed, dried tank in place, connect only the hose for supplying the working fluid to the pump (it is advisable to replace the clamp with a new, worm gear). We muffle the second hole (a cork made of a piece of polyethylene + an elastic band or wire), and lower the return hose into an empty one plastic bottle installed next to the tank.


4. We fill the reservoir with fresh working fluid according to the max level. We start the car engine for 2-3 seconds, turn it off. We add fresh working fluid again, start the engine ............ and so on until clean fresh working fluid comes out of the return line. Then we install the return hose in its place, while replacing the clamp with a new one. Add fluid to a level between the MIN and MAX marks.

5. It is advisable to rinse and dry the tank lid and mesh as well.

The next day after the procedure, do not be too lazy to open the hood, make sure that the fluid level is in the required range. Add or reduce if necessary.

According to the manufacturer's recommendation, the fluid in the power steering system is not changed during the entire life of the vehicle. However, if the fluid in the tank is heavily contaminated and darkened, then it should be replaced.

In case of severe contamination and darkening of the liquid, check the serviceability of the power steering pump and steering gear. Perhaps they need to be repaired.

You will need: a “22” key, a container for collecting working fluid, side cutters.
1. Raise the front of the car until the wheels are off the surface of the site and place the car on supports.



3. ... remove the clamp ...

Clamp disposable.


4. ... and disconnect the suction hose of the hydraulic steering line from the pump nozzle.


6. ... remove the bolt fitting and remove the hose tip.

Please note that the end of the pressure line is sealed on both sides with two copper rings. When assembling, replace the rings with new ones.

7. Lower the disconnected drain and pressure pipes into a previously prepared container.
8. Disconnect the block with wires from the ignition coil (see "").
9. Drain the fluid from the power steering system by turning on the starter two or three times and turning the steering wheel in both directions until it stops.
10. Attach pipelines and hoses to the power steering pump, fill the reservoir with fluid and bleed air from the power steering system.
The need for pumping occurs when air enters the hydraulic system during fluid replacement, repair work or in case of violation of tightness in operation. A sign of the presence of air in the system is the wedging of the steering wheel when trying to make a sharp turn. In addition, when the steering wheel is turned, the pump makes an increased noise, and the liquid in the tank usually foams.

The presence of air in the power steering system leads to premature failure of the power steering pump.

1. Fill the working fluid into the power steering system up to the “MAX” mark on the tank wall (see “Checking the level and topping up the working fluid in the power steering”).
2. Disconnect the block with wires from the ignition coil (see "Removing and installing the ignition coil").
3. Turning on the starter for 10-20 seconds, turn the steering wheel five to six times in both directions until it stops.

During pumping, add fluid to the tank, its level should not fall below the “MIN” mark on the wall of the tank.

4. Connect pads with wires to the ignition coil and start the engine.
5. Turn the steering wheel from lock to lock in both directions until air bubbles in the fluid in the power steering reservoir disappear.

Check that the fluid level in the power steering system reservoir barely changes when the steering wheel is turned from side to side. If the fluid level changes by more than 10 mm, and rises sharply when the engine is stopped, re-bleed the system.
