The effort to listen is to protect the car. In fact, this does not necessarily require very sensitive ears. If you listen to your car before you drive away, you may find problems early and avoid the breakdown of the road.
To hear if the car has any problems, just keep the engine in an idle state and listen to it. If there are abnormal sounds or vibrations, it is often because the tightness of the timing belt of the car is not standard, or the valve clearance may be It is already too big, even because the car has not entered the factory for a long time and it has caused serious knocking or carbon deposition.
If these problems occur, the owner will have to make a decision. If the belt needs to be replaced or adjusted, the natural situation should not be delayed. Although the problem of engine operation will not lead to an immediate crisis, the longer the delay, the more serious the situation will be. The engine will not only The shock is very severe, the car will also consume more fuel, and the life of the engine will naturally be greatly reduced.
Remind everyone that if the belt is damaged, it should be replaced immediately, replacing a belt up to 200 yuan, but if the car speeds up on the road, the belt suddenly breaks, it is not a 200 yuan problem, if serious, may have to go to the factory overhaul .
In addition, when the car is on the road, open the window first and listen to whether there is a strange sound when turning or moving forward. Common noises during cornering often come from the front-wheel drive shaft where the joint has been broken. When you hear intermittent choke, it may be a part of the exhaust pipe that breaks a hole, or which part or part of the bumper has fallen off.
