Can Chang an Star use a soft traction trailer after dismantling the engine?

Hello! Yes, but don't let the car in front drive so fast, you can still drag it slowly.

Wait for the water temperature to reach the starting temperature before starting: in general.

4. Try to avoid rapid acceleration and sudden braking, do not change the engine that is damaged, and run in the vehicle correctly. Today's EFI engines have a temperature-compensated control system. 3. I hope to inspire you, to meet the normal driving of the vehicle in the cold state, and there are fine iron pins in the oil that has been replaced.

This is important. If the EFI engine is preheated for a long time, it is generally specified to be less than 60 km h, which will only increase fuel consumption invisibly.

2. This plays a key role in prolonging the service life of the engine, the battery.

5. Air filter): Do not use idle speed to warm up the engine, keep driving at medium speed. Choose a good road surface during driving, oil filter:

Do not drive the engine at high revs while driving. Don't help others tow the trailer and coolant, there are the following aspects after the cylinder is repaired. In the future, it is necessary to change the engine oil and three cores every 5,000 kilometers, and to change the oil and three cores (gasoline filter element) once every 2,300 kilometers or so, and must be replenished in time if it is found that it is missing.

These aspects are for novices on the road, so during the run-in period can not exceed 75%-80% of the rated load, whether the electrolyte is sufficient: to avoid the overload of the engine: during the run-in period to check the oil frequently, the trailer has all kinds of harm but no benefit.

There are speed regulations at the beginning of the new car, which are all issues that need to be paid attention to. The new car is easy to cause damage to the machine parts when it runs at full load

1, this can increase the service life of the vehicle, the engine speed during the run-in period should be strictly stipulated between 2000-3000 rpm. In general, the throttle should be small. After the car is started, it should be heated in situ, and it should be exercised with reference to the standard of the run-in period of the new car.

The car runs in for a while and is easy to use.

If it is far away, it is recommended to use a hard tow or a back car! If you are close, you can try it, and you can dismantle it! The brakes will be very hard without assistance! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Observing the smoke color of the engine's exhaust emissions is a good way to judge the health of the car. As long as the observation is timely, it is not difficult to find appropriate methods and measures to eliminate the fault. Smoke exhaust fault phenomenon:

When the car is moving, black smoke comes out of the engine exhaust pipe, and the exhaust pipe (muffler) makes an abnormal sound. Diagnosis and elimination: 1. If a large amount of black smoke is discharged from the engine exhaust pipe, accompanied by the sound of firing guns, it can be concluded that the mixture is too thick.

Check whether the choke is fully open in time, and carry out high-speed maintenance if necessary. After the flameout, look at the main nozzle from the carburetor port, if there is oil injection or oil dripping, the oil level of the float chamber is too high, and it should be adjusted to the specified range, and the main measuring hole should be tightened or replaced. The air filter is clogged and should be cleaned or replaced.

2. If a small amount of black smoke is discharged from the engine exhaust pipe, accompanied by a rhythmic "burst" sound, it can be concluded that it is caused by a small number of cylinders not working or ignition timing inaccuracy. You can use the cylinder-by-cylinder disconnection method to find out the non-working cylinder, or check and correct the ignition timing. White smoke exhaust fault phenomenon:

A large amount of white smoke is emitted from the engine exhaust pipe while the car is moving. One is milky white smoke, the other is water vapor white smoke, and there are water droplets at the exhaust pipe mouth. Diagnosis and exclusion:

1. When a car parked in winter or rainy season starts for the first time, white smoke can often be seen. It doesn't matter, as soon as the engine temperature rises, the white smoke disappears and this condition does not need to be repaired. If the exhaust pipe becomes black smoke after the engine temperature rises, it indicates that the cylinder pressure is too low or individual cylinders are not working, which should be checked and eliminated.

2. When the engine is running, the exhaust pipe discharges a large amount of water vapor and white smoke, and should check whether there is water accumulation in the fuel tank, check whether the cylinder gasket is damaged, whether the cylinder block has cracks, and whether the cylinder liner sealing ring is good. Blue smoke exhaust fault phenomenon: The engine exhaust pipe of the car emits blue smoke or gray smoke while driving, and smells the smell of burning.

Diagnosis and elimination: 1. If the engine has been used for a long time or has reached the specified overhaul interval mileage (** parameters), and the engine power is insufficient, the main reason is that the piston and piston ring are seriously worn, and the oil is channeled due to poor sealing, which should be sent to the automobile repair shop for overhaul. 2. If the engine power performance is good, the oil pressure should be checked first, and if the oil pressure is too high, it should be adjusted.

Check the dipstick to see if the oil level is too high, if the oil level is too high, you should release excess oil. Check the air filter to see if the filter is clogged, and if it is clogged, the filter should be cleaned or replaced. Check that the air filter oil level is too high, and if the oil level is too high, excess oil should be discharged.

This may be because the engine is tightly assembled, and it is possible that you are replacing the supporting engine assembly, and there is no original engine***.

Hello, what have you checked?

Hello, you need to remove the pulley of the engine and remove the timing belt. Disassemble the muffler section connected to the exhaust manifold, remove the camshaft cover, and remove the cylinder head screws (remove all the things that need to be dismantled that are not discussed in detail).

Hello, when the engine temperature rises, after the thermostat is turned on, the water in the water tank and the water in the engine will also flow out. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

There is a hose connection between the bottom of the radiator and the engine, release the clamp, and put all the water away.

Hello, you need to get in the car, the fan turns and the car will be extinguished, I hope my answer can help you, I wish you a happy car!! [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Well, hello, you need to drain the water in the tank and drain the air when you add antifreeze. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

This does not need to change the water in the engine [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, according to the situation we have replaced, there is no durability after the original car is repaired, especially the new engine is not frost-resistant.

The new one is always better, and the old ones are out of trouble

Don't drag a car that is too much heavier than yourself, one is that your engine is too loaded, and the other is that you are afraid that you will not be able to drag it in some situations

There is also the use of L gear to tow, do not use D gear, the trailer speed should not be too high, easy to control.

Yes, the clutch plate will be damaged, it is recommended to go to the garage for inspection, or to do a location.

Is the oil pan gasketed? The large oil pan can't be gasketed, otherwise the crankshaft position sensor will have no signal.

Look at the valve clearance or timing. Crankshaft position sensor and cammetrical shaft position sensor.

There are many reasons, and it is better to explain where they are checked.

Ignition timing, distribution timing problems.

Is it right to ignite the fire? Is the oil pump good?

If it is not a hydraulic tappet, it may be that the valve clearance has been reduced.

And after the overhaul, whether the three filters have been replaced.
