For an old driver, cleaning the throttle must be no stranger, because every 20,000 kilometers or so, going to the 4S shop for maintenance will definitely let you clean the throttle. If the throttle is dirty, it is necessary to clean it, otherwise there will be some failures, which will greatly affect the driving experience. However, many people do not understand the operation process of cleaning the throttle. For example, do you need to remove it for cleaning? Will frequent disassembly affect its longevity? Today we will talk about several common questions about cleaning the throttle.
1. Whether it needs to be removed and washed
Whether or not you need to remove the throttle to clean it depends on the type of throttle and how easy it is to remove. It is undeniable that it is easier to remove and wash than not to dismantle and wash. Removing it can be cleaned not only from the front, but also from the back of the throttle baffle and the depths of the throttle. If you don't dismantle it, you can only clean the front of the throttle, and the reverse side of the baffle is not easy to clean in the corner near the hinge. Therefore, as long as it is easy to disassemble, it is recommended to remove it for cleaning, and it can be washed easily.
If the position of the throttle valve is very hidden, it is very troublesome to disassemble, and some models have cooling water pipes on it, which does not need to be disassembled. It should not be too troublesome to clean, and it can be washed carefully and patiently. Generally speaking, the electronic throttle valve is generally more convenient to disassemble, and some cable-type throttle valves may be more troublesome to disassemble, so the cable-type can not be disassembled. However, whenever you pull the throttle, there will be an idle motor.
When cleaning the throttle, this idle motor must be removed for cleaning, and it cannot be washed if it is not removed, because it is inside the throttle and cannot be seen at all. If the maintenance master did not disassemble and wash the idle motor, it means that he was lazy, which means that he has only done half of the work.
2. Will frequent disassembly cause throttle damage?
Regular operation will not, the throttle has a total of four screws, and the torque is not large, it is very easy to remove. Even if it is cleaned once every 20,000 kilometers, it needs to be cleaned ten times to run 200,000 kilometers, and most cars will be eliminated if they can't drive this kilometer. There is no problem with removing ordinary screws used in a home ten times, not to mention that there are relatively strict standard screws in the car, and it will not break if they are disassembled more than ten times. Of course, after dismantling, you still have to handle it gently, don't fall to the ground without holding it, which may affect its life.
3. There are more than a dozen yuan of cleaning agent and some hundreds of yuan, which one is better
Of course, the more expensive the better, and that's what everything looks like. Generally speaking, the big brands of throttle cleaners are more expensive, and there is a certain brand premium in them. Of course, in addition to brand differences, there are also different ingredients, and higher-priced products will use more efficient cleaning formulas, which can break down and remove carbon deposits faster, and maintenance workers can easily save time when they work. And the corrosiveness to the throttle is also less, it can not only quickly remove carbon deposits, but also will not corrode the metal of the throttle body, and will not cause damage to the throttle.
You can choose according to your budget and the age of the vehicle, even if it is more than ten yuan of throttle cleaner, it will not be used once or twice The throttle body will be corroded and damaged, and it is no problem to use it occasionally. If it is a new car and you plan to use it for a long time, it is better to choose a cleaner with a higher price and choose a big brand.
4. Will too frequent throttle cleaning affect the lifespan?
Basically, it does not affect the lifespan. In fact, some cars are damaged shortly after cleaning the throttle, but this is not simply caused by cleaning the throttle, but more because the throttle body itself is aging. The throttle body is aging and the shaft is not tightly sealed, so when the cleaning agent is sprayed, the cleaning agent will penetrate deep into the throttle body along the gap in the shaft. Because the cleaning agent has a certain corrosiveness, it will not be long before the circuit board and electronic components inside will be corroded and damaged.
Therefore, special attention should also be paid to cleaning the throttle valve with a large number of kilometers, although the carbon deposits at the shaft are large and difficult to clean, but the cleaning agent should not be sprayed at the shaft. It should be sprayed near the baffle or shaft to allow the detergent to run through on its own. Or spray the cleaner onto the rag, apply it to the carbon deposit, soak it for a while and then wipe it gently, and there will be no problems.
