Buick New LaCrosse Maintenance Manual (How to Zero Buick LaCrosse Maintenance)

Maintenance precautions for LaCrosse are as follows:

1. Wash the car in time after getting wet.

In case of heavy rain, clean it up in time after returning, otherwise it may cause mud accumulation in the gap under the car, which is the place where water can be hidden and the place where it is most prone to rust.

2. Beautiful paintings.

The acidic components in the rain have a strong corrosive effect on the automobile paint surface, which will cause damage to the automobile paint surface over time. Therefore, in the rainy season, it is best to give the car a sense of beauty in painting.

3. Chassis maintenance.

Chassis is the closest part to the ground, which is particularly affected by road conditions. Generally, this part is the easiest to rust, and the wheel shell may even be loose and perforated. Therefore, we must pay attention to the cleaning and anti-rust treatment of automobile chassis.

4. Ignition starts.

On rainy days, car owners often encounter the problem that the engine is not easy to start, and sometimes they are still weak even if they barely start. The biggest possibility of this problem is that the ignition system leaks due to humidity. In addition, it may be that the weather becomes cold when it rains, and the hot air sealed in the switchboard may condense into water droplets, causing a small flood in the switchboard and losing its normal ignition function. Once it is found that the high humidity of the ignition system leads to poor ignition and engine performance degradation, it is best to dry the inside and outside of the distributor and wires with a dry paper towel or dry cloth, and then spray the desiccant on the distributor cover, battery connector, spark plug, high-voltage line and ignition coil with a special desiccant spray can, and then start the engine later.

5. Brake to remove water.

Most automobile braking systems are double-wire vacuum assisted hydraulic braking. It is worth noting that the brake fluid that transmits braking force has strong water absorption. If water enters the brake fluid, the high temperature generated by friction will make the water evaporate during braking. However, gas is compressible, and being compressed in brake fluid will lead to brake failure or even failure. When it rains for a long time, the humidity of the air will get bigger and bigger. If there is a small amount of water in the brake fluid before the rainy season, it will be very dangerous. Some vehicles with serious brake fluid water absorption can see water droplets on the brake fluid oil cup cover. Therefore, the brake fluid must be checked during maintenance to ensure the safety of drivers and passengers.

6. Wiper maintenance.

The increase of rain will inevitably make the wiper take on more responsibilities, because the rainy road and sight are not conducive to driving. If the wiper fails to brush the rain, it will bring great danger to your driving safety. At this time, the wiper plays a very important role, so be more careful when checking and maintaining.

7. Always open the space.

Turning on the air conditioner is the best way to prevent indoor humidity. Even if the weather is cold, as long as the temperature is set and the air conditioner is turned on at the same time, the heating effect will not be reduced, but the dehumidification function will be increased. As soon as the weather clears up, park your car in the sun and open four windows to let the indoor air convection. The heated car body will quickly remove the water vapor deposited inside. When the car is not in use, desiccant is a good helper to replace air dehumidification. Air fresheners also have many advantages, saving electricity. Two batteries can be used continuously for a long time. With these two things, I am no longer afraid of the humid and turbid air coming at me.

8. Keep the sound away from humidity.

When the humidity increases in rainy days, there is often a layer of fog on the surface of CD records, which will cause reading drowsiness. It is best to scrub it every once in a while. In order to avoid getting wet when installing the CD-ROM drive, do not install it under the bottom plate and base. It is best to install it at the height of the car body, not at the rear windshield. Excessive temperature will accelerate the aging of electronic components and laser heads. In addition, in order to prevent the sound from being wet, you can also put a small dehumidifier in the trunk, which can be placed firmly to ensure that it will not fall over when driving, and you need to open the trunk occasionally to check it.

The LaCrosse engine has three models: 2.0T, 2.4 and 3.0.

ECOTEC-vvt 2.4l all-aluminum four-cylinder engine imported from America is a brand-new member of GM's global ECOTEC engine family. This 16 valve engine adopts D-VVT dual electronic variable valve timing system, with maximum horsepower 125kw/6400rpm, maximum torque of 225Nm/4800rpm and peak torque of 90% at low speed of 2400rpm. Thanks to the lightweight advantage of all-aluminum alloy engine, the excellent characteristics of D-VVT dual electronic variable valve timing, and multi-point sequential fuel injection (SFI), electronic throttle (ETC), double counter-rotating balance shaft, oil-cooled injection piston, life-long maintenance-free self-adjusting all-steel timing chain and 32-bit engine control module, the performance of LaCrosse 2.4 engine far exceeds that of the previous generation LaCrosse 2.5 engine.

Buick LaCrosse's AFMV63.0L engine The AFMV63.0L engine of Buick LaCrosse's high-end model is specially developed for Buick LaCrosse by the General Motors Power Department of North America, with the maximum output power 136kw/5400rpm and the peak torque of 253Nm/4400rpm.
