Important vehicle maintenance stages

1.6000KM-7000KM: change mechanical oil

2.1.5 year of usage: change water tank solution

3.40,000KM~50,000km: change spark plug. Air core should be changed about 40,000km stage.

4.Spray it upon maintenance.

5.Battery life is at least 4 years.

6.Wheel tire life is about 50,000km.

7.New car doesn’t need oil tank solution.

ABS braking system
Upon maintenance of vehicles, focus is security. Engine failure makes car malfunction and can’t be moved. That’s all. Braking problem is very dangerous, something about the safety of our life. Checking the brake system must be particularly careful. Even a light loss cannot be allowed. Repeat the checking is necessary.

Unauthorized replacement of the battery could result in failure or damage of the computer circuit.

When the battery warning light is on, it doesn’t mean battery is damaged. No matter what the model or brand is, the battery indicator light directly affects the power generator. It seldom stands for the battery failure results I car malfunctions.

The power voltage and size of the battery are different according to the original manufacturer’s default. If the battery specification is wrong, the computer circuit could be burn. This damage recovery will cost more than US$3,000 for a big repair.

Several important works to maintain the used car

1.You have to find an experienced engineer to regularly deal with who knows your car very well.

2.Look out fatal problem or risk such as braking system, ignition system, and fuel burning system.

3.The trouble that leads to stop working on driving is mostly petro leakage. If this leakage happens surrounding the engine, replace a small piece of oil seals or gasket is enough. If the trouble is internal heavy consumption of the petro, to find the exact reason is difficult. You need to visit a professional engineer. However, you had better investigate the petro consumption amount or fuel supplement amount every week or month. Otherwise, stop on the road is troublesome.

On driving a used car on the high way, you should make sure the key matters below;

1.Have you found the main items for maintenance, if you drive an old car?

2.Have you found the fatal parts which shall lead to heavy accident on high-speed drive? You have to pay more attention to them.
3.Is the water tank full enough?
4. Please get to the repair center when you find that the car is powerless after it is accelerated significantly?

5.Please check if brake function is normal or not?
6.It is very dangerous that the car still slides after pulling the parking brake.
7. The old car over a decade may generate electrical fire that could burn the car.

8.For the risk of burning, you have to find out the wires necessary to replace immediately.

9.Clean the car after a good maintenance especially the location around the engine and the surrounding parts.

10.Is the oil too old to drive the car?

Flameout, the old trouble
Check Air Flow Meter, if the box button is lost or not. When the Meter beaks and is poured into air, it shall cause flameout.

Headlamps are not working.
Change the inside bulbs or the whole lamp set? Normally, just change the bulbs is enough.

Sink cleaning
Open the engine hood, use air guns to spray water, and push out the dust and the mosquito body.

Tire spare room leaks out water.
At the bottom of the spare room, open a black rubber in order to let the water flow out..

Engine throttle shakes very seriously. It seems to result from inability to absorb the oil.

Normally, you shall check several places,
1. Ignition system: Spark plugs shall be replaced on a regular basis

2. Intake system: Clean the dust and coke on the air devices.

3. Fuel system: Check and replace fuel filter (petrol pump) and keep it clean.

Do not use cheap solution that could hurt the seals or the wire.

Remember to change the spark plug
Every 30,000km, to replace the spark plug with a new one is necessary.

Having different and strange sound on starting

You had better check whether the belt drive is tight or not. (When the engine is visually whether its belt drive the swing or the Big Dipper action case), especially the water pump drive belts is often neglected.

High temperature indicator is on.

1.Fog lights, oil cooler, transmission oil cooler will affect the cooling water tank. Please check them.

2.Don’t install any equipment between the water tank and water shield

3.Have a look at whether the radiator and the front row of cold air smoothly or not?

Inability feeling or high petro consumption of the engine
Too much coke absorbs the petro and the high temperature happens on starting, these two factors make engine weak. We suggest that you clean the coke.

Very strong gasoline smell
When you drive an old car on the mountain road, there could be an very strong gasoline smell. Because the car goes higher and higher,
the oil air flows upstream or gas pipe could break, gasoline smell will come out.

Engine warning light is always on, but the car is driven in good condition as usual.
This result from oil supply is too thick. Several items should be checked,
1. Engine pcv is too tight or pipe leaks air.
2. Check oxygen content, the normal value will jump between 0.1 ~ 1.0V.
3. Check if the computer works well or not, by original factory devices.
4. Exhaust pipes exists a serious coke problem.

Engine doesn’t work when you start it. It works again after a period of wait.

The items should be checked are, start motor, fuel pomp, and power.

After start-up or stepping the gasoline switch, you cannot move the car and it is just shaking.

Please check the ignition system, ignition coil, silicon wire, and spark plug.

The temperature of Water tank is too high.
When the car is running high speed, engine works with high temperature and heat sinking is not well, the temperature of Water tank goes too high.
1. Please check the pcv or cylinder cover if the gas blowing is smooth or not? , the water temperature too low will fuel.
2. Replace the corroded water tank is effective.
 3. Replacement of water turtle (temperature regulator) is effective
4. Please also replace the tank pump
 5. Clean the engine room and cold arrangement is effective.

6. Replace fan motor is effective.

How to do if the engine temperature is too high?
At the middle between engine body and cylinder head, there is a gasket. It is called cylinder mattress pieces. After the engine temperature goes high, this gasket is easy to be burn. This is the part that you have to check first. Second, check water tank, the engine, if it leaks water or not.

When parking, the ground exists oil. There is strange sound after start.

You have to replace the oil for power pilot wheel, oil tank, pipe and original pump.

Understanding the engine oil
The main effect of engine oil is to provide internal smooth access and extend mechanical life
Therefore, understanding the specifications of the engine oil is becoming important for car owners. At present the brand launch of the engine oil, is in compliance with the American Petroleum Institute
(The API) specifications, under the test set is made of, and the Association has developed a special quality in accordance with oil SA, SB, SC, SD Until now the latest SJ and other levels of the market at present most of the corresponding gasoline engine oil that belongs to SJ rating.
Most engine oils are API and SAE specifications in accordance with the manufacturer, so in case oil or packaging specifications should be clearly marked. You must pay attention to the time of purchase. In addition to the quality level of oil, the oil specification is also important to understand the time of purchase the item. Specification is in general the oil viscosity to distinguish. SAE Institute is also set according to the U.S. norm, so all the oil on the market in housing or packaging should be marked out of the oil's viscosity index
Also based on figures with the letter W to mark, including the 0W-30, 5W-40 or 10W-50 and many other types.
Oil specification label methods, W stands for winter, in front of the figures represent the low-temperature startup viscosity, such as 0W shall be -30 ° when the flow index for 3250mPas,
5W is -25 ° when 3500mPas, the larger the number the higher the temperature corresponding to the start; back the same number of representatives of viscosity,
However, most units of state for the 100 ° flow index, the higher the number the greater the viscosity, it is for domestic hot weather,
Behind the meaning of the figures also represent greater than the previous figure.

The choice of oil viscosity is very important! Taiwan is a very hot summer, better not to use 0w-30.5w-30.10w-30 engine oil (less heat!) New car and used car with a 5w-40.10w-40 can be, used car and old car only with the 5w-50.10w-50 oil.
