How to do maintenance of automotive sealing strip
On the doors, windows and skylights edge of the car, we find that the presence of the sealing strip . These less from the eye of the sealing strip, is often in the summer, the owners were easy to overlook vehicle maintenance issues .
It is well known automotive sealing characteristics because it has only played a gum seal . If the seal long-term exposure , it is easy to aging , cracking, sealing performance is compromised , not only affect the sound insulation inside the environment,amper seals there will be severe leakage, seepage and other phenomena . Automotive beauty experts have pointed out , to do maintenance work seal , vehicle owners should start from the beginning of the everyday little things : The first step is to do the cleaning job seal , the owner can be every one or two quarters of the car seal for a cleaning . Concrete can be rubbed with a clean wet sponge rails, dust groove on , then wipe dry sponge once more to keep clean the sealing strip . The operation is quite simple , the basic need to dedicated car wash can be carried out .
When using high-pressure water washing If so, remember not to water sprayed directly at the seal , or easy to make ring deformed under high pressure water jet impact , over time will affect the sealing performance of the seal , the car is more easily into the water. In addition , car owners have to pay attention to the parking place . When faced with circumstances require prolonged outdoor docked , the vehicle should try to avoid direct exposure in the sun , if you can , the best vehicle for covering some reflective sewing to prevent the doors , skylights edge seal due to heat deformation and cracking.
If it can not be avoided Fixed Length plastic seal, do not splash through direct physical cooling methods , the larger the temperature difference tends to change the internal structure of the seal , resulting in deformation cracking.

Do not use frozen snow pretty trick car
After the snow in order to avoid embarrassment , the first frost, the main attention to the car before it is frozen , freeze several parts of the car's afraid of :
1 , some non- electronic remote lock keyhole first class attention , especially after rainy and snowy weather earlier , the owner of a piece of cloth wrapped around advance or paper wrapped about the keyhole in the car , this can be avoided As the frozen block keyhole .
2 , plastic vehicles often use seal parts : such as door seams , sunroof, trunk , etc. is easy because of the impact of frozen brittle , misuse can cause some unnecessary small abrasions. If forced open , then the owners will lead Mifengbuyan , causing leakage and leakage .
3 , the wiper will not be used due to snow cover and , of course, in the winter, car antifreeze , motor oil should be more than the lowest temperature weather , so as to ensure the normal road car , diesel car owners have to open the corresponding reducing diesel label , avoid direct damage to the oil freezing .
Impulsive one : windows, doors were forced open frozen
After the snow, the car is easy to crack, because the residual snow leading to the door open. See here some owners will say up pouring hot water can , in fact, this is not very secure, and even the owner of a day to drive to the snow , this is a very undesirable way . Because the fits and starts , then it is easy to damage the door seal and paint will therefore subject to different degrees of damage.
When the door was frozen encounter , the owner can try if you can open the door there , if there is a door can be opened , then all problems can be solved, car owners can use a hair dryer so heating equipment or direct start up the car and so the water temperature enhance the temperature inside the car with air conditioning , so the door and other parts of the convergence of melting snow . If the doors are all frozen , the owner may consider preparing a small portable dryer or hair dryer . If there is no such device , the owner is best not to use too hot water to melt the snow around the door , with a dry cloth to clean the car door after door open . This process must be carried out quickly to avoid secondary freezing. Of course, the latter method is not very recommended.
Windows were frozen , then heated air conditioning is the best way . But in order to save fuel , owners of the best preparation for a northern snow shovel to remove snow vehicle first , and then the warm breezes of the window air conditioner residual ice .
Two impulses : Wiper is forced to use frozen
When the wiper is frozen, the owners do not hurry . Forced to use it, ranging from damage to the rubber wiper , causing trouble for future use , heavy electrical wiper burned directly , it can no longer be used completely .
It is a professional auto repair shop technician said that the wiper north, is the most easily damaged vehicle parts , vehicle owners after snowy flame alight , in addition to lock the door but also the wiper stand up , do not let it stick to the glass , frozen in trouble on . The second is often under freezing rain north , to de-icing snow shovel can be used as soon as possible , but do not use force wiper de-icer , so make your car 's wiper rubber parts of a gap , which is a lot of vehicle owners say they Wiper scraping a reason not clean water .
The technical staff to remind owners , snow thaw wiper Do not use hot water , hot water can easily lead to vehicle glass burst , wiper thermal expansion and contraction deformation. high security cable sealsThis time the owners still consider snow with warm air into the car and then slowly melting ice on the glass and wiper , is the best solution.
Impulse to three : car brakes are frozen forcibly
Many owners may be in the car this morning , just started to hear " bang" , which is above the ice after being frozen brakes or handbrake was forcibly detach the sound .
This case is so long , it is likely to pull loose brakes, affect the braking distance of the car. To remind the industry , which generally occurs after snow in the morning , the car will start when some difficulty , if the handbrake is frozen fit to your car, try to reverse gear oil, but there is no one to pay attention to the rear or objects . Frozen brakes , then the owner can take the stick to ice burst open .
Snow equipment recommended
A car , " raincoat" ,plastic padlock security seals which can effectively prevent the car cover car was frozen, but the drawback is the time will win more strenuous .
2 , snow shovel , preferably with a stiff brush . Effective de-icing snow , winter driving essential .
3 , car hair dryer , which can effectively remove the door gap snow .

Focus position of the vehicle which sealed
Focus position of the vehicle sealing the following areas:
First, the vehicle doors and windows sealed
Before installing the glass doors of the vehicle to clear the debris carefully notch within such as mortar, brick dust, wood, etc., should be placed carefully on the glass, ensuring that both sides of the gap is uniform and timely than the positive fixed to prevent collisions shift deviate from the slot center. Rubber seal can not pull too tight, cutting length longer than the assembly length 20-30mm. When installing the mosaic in place, flat surfaces, and glass notch in close contact, so that the glass surrounding the force evenly. In the corner of the rubber should be beveled off and disconnect the injection of glue at the firm. When caulk sealant fixed glass, you should use rubber or rubber block glass and choked, leaving voids plastic injection, plastic injection depth should not be less than 5mm, before the glue curing, the glass should be kept free from vibration.
Second, the leading edge of the vehicle seal, the seal along the side edges and
Support from the hood, on the bonnet leading edge, a trailing edge and side edges of the body of the anastomotic site and paste, can the gap between the hood and the body effectively sealed vehicles on the way, can accelerate the air from the intake gate through the improved thermal performance. At the same time, you can reduce the hood and the front part, the friction between the left and right front fender, reducing noise and friction caused by the bump. If the gap is large, you can paste layers.
