New cars are good, but used cars are more cost-effective for many consumers. After understanding the new car, some people will look into the used car market. They think that buying a used car is more cost-effective. With the prevalence of used cars, the used car market is also expanding, and a series of large-scale used car trading platforms have emerged. How to buy an economical and affordable used car? First, check the brake pads and brake discs The more cars open, the more brake wear. So look at the extent of wear on the brake pads and brake discs. Under normal circumstances, about 50,000 kilometers need to replace the brakes, about 100,000 kilometers need to replace the brakes. The brake pads can be touched by hand to determine the degree of wear. As shown below: Second, check the engine for signs of burning oil Open the engine cover, turn on the fuel injection port, let friends go into the air to stop the step on the throttle, the engine speed stepped on 4000 rpm, take a look at the oil injection mouth plus no obvious blue smoke, if there is a lot of blue smoke Ejection shows that the wear between the piston ring and the cylinder liner has become severe, resulting in burning of the engine oil due to the excessive clearance. Third, according to the comprehensive judgment of the vehicle condition One of the important factors in the vehicle's condition is that according to time, the date of the license can't be changed, so in general we count 30,000 kilometers as the mileage of a car. If there is a large deviation in the number of kilometers, it is necessary to make a comprehensive judgment based on the condition of the vehicle and the other party's expression. Fourth, look at the interior The car is much more open, and the longer it takes to sit in the cab. Therefore, the interior mainly depends on the degree of wear of the steering wheel, the seat, the shift lever, and the handbrake. These are the few points that as long as you notice, wear and tear can be judged completely. Pay attention to the seat focus on the driver's seat, remember to feel the flexibility of the cushion. Editor's Note: A car pedal is a place that is easily overlooked. It is also difficult to replace it with a new one, so everyone can observe this place as much as possible when buying a car. Buying used cars is also expensive and expensive, if the price of high cars will be better. The plate heat exchanger is made from
