Car “overwintering” three inspections this winter will not be too cold[汽车维修知识]

Winter is here, friends who are driving must carefully do three inspections to protect the car through the winter. Tires: Winter is cold and dry,TiresThe rubber becomes hard and relatively brittle, which is easy to leak air and puncture tires, and it is more difficult to control when the road is wet and slippery in icy and snowy weather. Therefore, check the tire pressure and wear conditions carefully. If there are obvious injuries or cracks, it needs to be repaired or replaced in time. The winter anti-skid tires can be replaced if possible. In addition, the friction coefficient of the road surface in winter is low, and the tire pressure should not be too high or too low. Generally, it is enough to maintain 2.1-2.3 atmospheres. Warm air: In winter, try to see if there is hot air, whether the fan is running abnormally, and whether the air duct is unobstructed. In particular, pay attention to whether the defrosting air outlet under the windshield is normal and whether the heat is sufficient. Also check whether there is any debris in the air inlet, air inlet grille, electronic fan, etc. Compressed air can be used to blow away the dust. When the engine is cooling, a water gun can be used to flush the above-mentioned parts from the inside to the outside. In addition, vinegar fumigation should be used to disinfect the warm air outlet before use, the air conditioner should be circulated to the maximum air volume, and the doors and windows should be closed for 10 to 15 minutes. Engine oil: switch to high-quality and high-efficiency before winterAntifreezeAndLubricating oil, Choosing a lower viscosity oil will be better for reducing mechanical wear.Pay attention to the engine before filling the antifreezeCooling systemPerform cleaning. Finally, I would like to remind you that the anti-freezing winter glass water should be replaced in the environment below 0 ℃ in winter, and an appropriate proportion of alcohol can be added to the glass water to achieve the purpose of reducing the freezing point and anti-freezing.From: Dahe.com Related: ·Although the battery enjoys "free of maintenance", it also needs frequent maintenance[汽车维修知识]
