Roll up your sleeves: cleaning the throttle

Cleaning the throttle requires knowledge of its location. Some drivers do this procedure on their own, without resorting to repair services.

The throttle is located directly above the intake manifold. This mechanism has a very simple principle of operation: the more it is open, the larger the cross-section is formed, through which more air can flow into the intake manifold per unit time. This factor increases fuel consumption and increases the car's power. The driver controls the degree of opening of the throttle, pressing the accelerator pedal. These two mechanisms have a direct connection. When you press the gas pedal, the flap opens, if you press it all the way, the throttle opens as much as possible.

This detail in the car does not require special attention. If you do not cause direct damage to the throttle, it can last the entire life of the machine. But nevertheless, over time, it can become contaminated. It can appear in oil deposits of dark color on the walls of the damper body, as well as in internal air channels. Such contamination can lead to deterioration of the car. Therefore, if there are such symptoms, then cleaning the throttle is required.

The cause of the formation of pollution can be oil dust, it penetrates through the valve cover through the ventilation tube of crankcase gases.

Cleaning the throttle is a simple procedure. It must be produced once for 50-55 thousand kilometers of run.

Cleaning of the throttle valve (VAZ, DEU, Chevrolet, Opel, etc.) is carried out only on a cooled engine to protect yourself from unwanted burns. To work, you need a different screwdriver, end head number 13 and a washing liquid in the can.

Remove the plastic cover on the engine. To remove the internal pressure in the cooling system, unscrew the cap of the expansion tank. Remove the forced ventilation hose. If the channel of this part is clogged, the crankcase gases along with the incoming oil pass through the entire branch of ventilation. We unscrew the clamps and remove the heating tubes of the throttle assembly. For some time they can be covered with old candles. Further we unscrew a collar and we remove a hose of system of ventilation of a gasoline tank. Then it remains only to unscrew the nuts, remove the cable and get the throttle assembly. Next we take a balloon with a cleaner and launder the damper and all the channels. We carefully examine the calibrated channel of forced ventilation of the crankcase. It is necessary to remove the idling regulator , we also wash its channel in the throttle assembly. All. Now you need to collect everything in the reverse order and enjoy the work of your car.

All specialists evaluate positively the cleaning of the nozzles with ultrasound. This is a more efficient and effective method of cleaning. With this method, only the nozzles are rinsed, but you can monitor this process and repeat the procedure as many times until the desired result is obtained. With this method of repair, it is possible to simultaneously eliminate various malfunctions. Ultrasound cleans injectors more efficiently, but dismantling and assembly of parts, as well as replacement of sealing elements, can significantly increase the cost of the service.
