Ching Ming Festival is a traditional Chinese festival, the most important festival of sacrifice, is the day of worship and the grave. Ching Ming Festival, also known as outing Festival, is greeted with sunshine and vegetation Tulv of the season, it is also a good time people spring outing. Whether you are Jisao return, return, or outing in the long-distance Drive After all the pairs of Car To do some maintenance.
Check for debris trailers In the way by car, there are always leaves, plastic bags and wrapped in dead insects and other debris into the outlet or inlet grille, electronic cooling fan, etc., while the water tank, air-conditioning condensers will be covered with dust. If a vehicle or the road less traveled a number of experienced flooding, etc., the vehicle may be damp carpet, mold and odors. The compartments will inevitably accumulate a lot of dust, especially the carpet, roof and door trim parts such as suede wrapped.

If the vehicle carpet, roof and door trim and other parts of dusty suede package, need professional steam cleaning machine for dry cleaning treatment. The instrument panel and other parts are hard contaminated dust, but obliquely between should be cleaned with a cloth or cotton swab. Wet carpet to be dry in time, and check the situation of damp location.
Check the "three oil" "Two Rivers" Many owners in the Ching Ming
dawn, drove his family to the ancestral graves, or taking advantage of the warmth of spring outing to the countryside, travel anywhere from several hundreds of kilometers, as many thousands of kilometers. After a long journey, the car the "blood" will inevitably be leakage and consumption. In addition, the engine working under continuous high temperature may cause Engine oil Metamorphism, therefore, long-distance driving should be three after the two oil and water testing.
Three oil: gasoline is relatively simple inspection, vehicle owners need look no gas gauge on the line. Check the oil, the owner pulled out the ruler as long as the oil, cleaned and then put there a while and then pull out every other view, the oil level in the on-line and off the assembly line can be between the. If there are impurities in oil or gasoline, and tobacco showed light blue tail, a problem on that engine, the engine's cylinder wall may Wear and tear Serious and should be quickly into the plant maintenance. View Brake Oil, brake oil as long as the surface is not less than the offline box on the line. Brake oil is found to have bubbles or dirty, it indicates need to replace the brake fluid has changed.
2 Water: water tank owners can check yourself, the owner checks the water tank when the tank should pay attention to the MIN line, if the MIN line the need for timely replenishment. Overheating in the engine and water tank, the owner shall not filling Coolant This will make the water splash out and hurt. Last check wiper water, check to see if sufficient, whether the wiper tank sediment, sediment if the owner is best to remove the tank to clean, wash after installed, and then filled with water wiper .
Check Power Assembly, drive system with or without oil leakage
Zijia ancestors, outing of the road did not have as smooth and spacious city roads in some areas is still relatively poor road conditions, long-term drivers in the city roads lack the experience of driving these roads, it is possible Chassis scratch phenomenon occurs. To car's "health", returned by car, we must check whether the injured vehicle chassis, engine, gearbox and so there is no oil leakage, and if so, must be immediately resolved to the professional auto repair shop.
In addition, the car will often experience long-term operation and low-grade gasoline torture, eating well, dry much more, these two conditions on the damage to the car are very large, it must give the car back after the "washing gastric lavage. "
Journey in the way prostitution, may make the engine body, engine radiator coated in mud, seriously affecting the work of the engine's heat, when the professional car dealers need to use special cleaning agents to clean the engine and radiator. Note that, since the circuit complexity of the engine compartment, wash with water directly to the engine is very dangerous.

Is wide angle rear window lens same as fresnel lens?
is the wide angle rear window lens same as the fresnel lens used in projectors for magnification.somewhere i read wide angle rear window lens has got a negative focal length.following are the specifications i require.::
Thickness: 0.4mm
Weight: 44 grams
Material: optical PVC
Groove pitch: 0.3mm
Focal length: 30cm (~1 FT)
Size: 7 inch x 10 inch
so is it wise to buy a wide angle rear window lens??
Yes. Those lenses you see on the rear windows of RVs are fresnal lenses.
Why do you need a rear window lens? I have ever only seen them on RVs and not cars. Maybe a rear-view camera would be a better choice depending on the application.
