The “lova” in chevrolet is a car built entirely on the original design of the troika, not only to adapt to chinese consumers’ aesthetic habits, but also to expand the interior of the car to meet the needs of domestic cars. It is a small car targeted at consumers who are seeking to live with a sense of quality, and it is a model of a popular car in shanghai that addresses the needs of china’s target consumers and integrates the design ideas of the world’s top designers, as well as the fine domestic sanctuaries built by the global technological resources of general motors。
Last february, lova's “love” came on the market for more than a year now, and there are many car owners, who experience different situations in the actual use of maintenance and use. How do normal repairs and maintenance work better? In recent days, relevant experts have provided detailed notes and suggestions on the use of the reader's questions.
Interpret:
Air conditioning
Readers showed that the wind cooling was still very fast, but the air conditioner was used in 1. 4l's vehicle, slightly over. When the air conditioner was turned on, the power decreased significantly, and when the air conditioner was turned on, it became significantly softer in the second and third tranches, and the noise from the retrofitting of the door increased, but the speed was rather weak. In case of this problem, there is no need to overstretch, and there is a need to communicate with the maintenance staff at the vehicle maintenance service and to adjust the maintenance。
Particular attention is paid to:
Special attention to the renovation of the conveyor belt
Do not refurbish the belt, which would cause the material to break and damage to the belt. Check whether all the belts are fractured, fractured, worn and tightened and, if necessary, adjust or replace them。
The steering wheel is in a forward position and turning to the column lock
The wheel must remain in a positive forward position and the pole must be in a “lock” position before it is disengaged from the rotor to the pole or the middle axis, otherwise it may lead to the entanglement of the circle in the shift column, thereby damaging the wiring。
Special attention to engine emissions
The retrofitting of engines or their components affects the emission control of vehicles and has the potential to light up the malfunction light (mil). The modifications also prevent the vehicle from passing the required emission inspection/maintenance test。
About carpet replacement
In order to avoid personal injury and damage to vehicles, carpets of the same thickness and material size as those originally installed should be used for repair or replacement of carpets, and the carpets restored to their original position。
Engine hatch lock operation
When opening the hood of the engine, observe the operation of the auxiliary lock, and when the main lock is released, the auxiliary lock shall prevent the hood from being fully opened. The hood of the engine must be secure。
Replacement of spark plug lead
Clean up the guidance lines and check if they are burned, fractured or otherwise damaged. Check if the steering cord is installed on the direct ignition system module and spark plugs and, if necessary, replace the guide。

The experts recommend that:
1. For each 1,000 km journey or every 12 months, the plate and drum brake lining shall be inspected, the thickness of the brake and grinding lining shall be carefully checked, and if it is expected that the brake or polishing lining will not allow for the next scheduled maintenance time, it shall be replaced, the brake fluid shall be inspected and the airhole shall be covered. Make sure they are clean and clear。
2. Air filter cores should be replaced for each 40,000 km journey and, under dust-intensive conditions, replacement intervals for air filters need to be shortened。
Use manual:
The stock of spare tires and jacks
Keep an eye on the sound in the back of the vehicle. The spares, all equipment and tools must always be fixed and, after each use, lubricated jacks or screwdrivers。
Clean oil road system
The smoothness of the oil road system is key to the stability of the vehicle and the saving of fuel. After a long journey, cars generate carbon deposits in gas-inducing systems, such as engine jets and gas valves, due to different effects such as climate, environmental changes, oil or driving habits, where the jet mouths are close to the gas valves and the temperature is very high, and are most likely to cause local high temperature oxidation of the oil, resulting in carbon accumulation. Carbon accumulation reduces driving performance, increases exhaust pollution, fuel consumption and the initiation of bad glittering in cold vehicles, and it is recommended that the main vehicle should be cleaned once after 20,000 kilometres。
Such basic clean-up is actually easy, and it is proposed to use “full-powered oil road cleaners” to clean the oil tanks, pipelines, nozzles, petrochemicals, vents, combustion rooms and the head of the cylinders as a whole。
In addition, because modern high-performance engines are designed to provide a fuller exhaust for ingestion, there are three to six gas doors per cylinder. Some engines are designed to open gas doors at a time that changes the speed and load of the engine, but the glue affects the opening time of the gas doors and the accuracy of the opening. If the valve is not smooth, it is not possible to provide an appropriate amount of mixed gas, resulting in a weak, low-speed twitching engine or even a fire out. In order to improve this situation, the owner of the vehicle may use a “multi-valve cleaner” to clean up the sediment near the valve and restore the motor strength by pouring the cleaning agent directly into the tank every 5,000 kilometres。
