Do &ldquo medical checkup&rdquoIn vehicles, private cars make up the vast majority. Most of these car owners just came back from a road trip during the long vacation, so it is very necessary to come back to their cars for comprehensive maintenance.
Now introduce the following ten tests, you will be able to handle yourself.
1. Scratch the body.
While on a road trip, due to the owner's unfamiliarity with the road surface or the poor condition of part of the road, there may be obvious scratches and dents on the outside of the vehicle, especially at the front bumper. Therefore, there are many car owners who will paint the exterior of their vehicles. However, according to professionals at auto repair companies, some of the cracks in the paint caused by impacts are not very large, so most people think that the aesthetics of the vehicle are not affected and turn a blind eye to this. In fact, the metal underneath the paint has already begun to rust. By the time the owner can look at it from the outside, the interior metal layer has rusted badly. I'm afraid of hurting the bones when I rework it.
2. Chassis Repair
Some cars scrape their chassis on road trips, but they are often overlooked during repairs. According to professionals, if you find the chassis abnormal, the steering wheel wobbles, and the vehicle is parked with oil, it means the chassis has been damaged. This is because after the road obstacle scratches the chassis, some parts of the chassis may be deformed, especially the upper and lower swing arms, left and right directional tie rods and so on. In addition, even some minor scratches can cause minor leakage of the engine oil pan or the gearbox oil pan, which are problems that owners cannot detect in time through self-inspection. Therefore, the owner is best to do professional chassis rust care or spray paint to make the chassis armored once.
3. Brakes should be sensitive.
Going on the road trip long car, the brake system is prone to problems. In some auto repair shops, come to check the brake system of the car lined up a long line. The first thing to observe is whether the surface of the brake disk is smooth. If there are obvious grooves, this is due to the fact that when the vehicle is traveling on gravel roads, some fine sand and gravel get stuck between the brake disc and the wing plate, constantly rubbing the surface of the brake disc. If the situation is serious, it will significantly affect the braking performance. At this point, you need to drive to a designated service station to check whether the brake pads need to be replaced. If you notice a drop in the brake fluid level, immediately check the brake fluid line for leaks. Before checking the brakes, carefully wipe off any dust from the master cylinder to prevent dust from falling into the reservoir. For cylinders without a scale, keep the fluid level 6 mm from the top of the cylinder. If there is a scale, simply keep the fluid level above the scale. Professionals remind car owners and friends to understand some common sense in maintenance. If you do maintenance in some street stores, you should always remind the maintenance staff to repair items.
4. Keep tire pressure normal.
On the way to a road trip, the tires are the place to focus on because they are in contact with the ground the longest and wear the most. If the tire is a radial tire, the sidewall is the weakest part, because the whole radial tire only sidewall without steel wire, so it must be used very carefully. If you drive at high speed on a road with poor road conditions, the tire may hit a deep pothole or other foreign object, causing the tire to be severely squeezed and deformed between the impactor and the rim flange, resulting in yarn breakage of the tire wall cord fabric. At this point, the gas inside the empty tire will push upward from the broken yarn, forming a bulge. If you find a tire bulge, replace it in time, or it will easily cause a blowout at high speed. Measure the tire pressure to see if it is within the normal range. If there is any abnormality, it should be inflated and adjusted in time.
5. Oil should be enough.
Whether the oil is sufficient is related to the normal operation of the engine. Therefore, when returning from traveling on the road, be sure to check whether the oil is sufficient. The steps are as follows:With the engine off, first pull out the dipstick and wipe it with a cloth; then reinsert the dipstick &mdash&mdash try to insert it to the bottom, otherwise the reading will be inaccurate; finally, pull out the dipstick and check the oil level at the end of the dipstick.
If the oil level is below or slightly above the low level, remove the oil filler cap and add oil. The amount of oil to be added is between the low and high oil level lines on the dipstick. Take care to tighten the oil cap after filling.
6. Coolant level should meet the standard.
When the engine is cooling, look at the clear coolant tank. If the level stays between the &ldquofluid tank's; F&rdquo and &otherL&rdquo markers, it meets the requirements. If the liquid level is at &ldquoL&rdquo or below, coolant should be added to bring the level up to the &ldquoF&rdquo queue. After adding coolant, if the coolant level drops within a short time, a leak may occur. Visually inspect the radiator, hoses, engine coolant filler cap, radiator and discharge plugs, and water pump to see if any water is coming out. If no leak is found, the vehicle needs to be taken to a designated service station for further testing. Note that to prevent burns, do not remove the radiator cap while the engine is still hot.
7. Battery Repair Port
After long hours of driving, your car's battery may loosen due to strong vibration, or battery fluid may spill out. At this time, you need to check the outside of the battery for corrosion or loose, cracked or pressed loose connectors. If the battery is corroded by spilled battery fluid, it needs to be cleaned with a mixture of warm water and baking soda water, and the joints should be greased to prevent further corrosion. If the connector connection is loose, the nut of the clamp should be tightened, but not too tight, just to hold the battery in its position, too tight will damage the battery case.
8. Dusting the compartment
On the way to a road trip, car owners like to roll down the windows and observe the scenery outside the car (Gallery Forum) because they are traveling in a completely unfamiliar environment. However, because the windows are open for a long time, a lot of dust accumulates inside the car, especially on the carpet, roof, door trims and other suede-wrapped parts, which are difficult to deal with. It takes a professional steam cleaner to dry clean these parts. Other parts of the cabin, such as the dashboard, are less susceptible to dust, but corners should also be cleaned with a rag or cotton swab to avoid dust buildup.
9. Empty to adjust refrigerant and check for leaks.
Air conditioning and maintenance can be divided into two areas. First, carefully check the front of the car's empty air conditioning refrigerant tank for leaks due to collision or impact. If leaking, it is necessary to fill the leak and refill the refrigerant as soon as possible. The second scenario is that there is a lot of dust in the radiator and ducts as a result of the harsh environment during the trip. For the dust inside the air conditioning ducts, although it cannot be touched directly, it can be removed by injecting a special cleaning agent directly into the air inlet of the air conditioning, and then turning on the internal circulation of the air conditioning. This cleaner is non-corrosive and there is no need to worry about damaging the plastic parts of the duct.
10. Degrease the glass.
Can glass have maintenance besides water washing? Yes, glass maintenance is very academic. Not all problems can be solved with a water rinse. For example, the glass is stained with oil, the naked eye may not be able to observe, but the efficiency of the wiper will be greatly reduced. In this case, a degreasing cleaner must be used to remove the oil.
