Hello, just a normal forward rotation is fine.

Thank you for using, I hope mine can help you, if I can help you it would be great, if there is anything you don't understand or don't understand, you can continue to ask, I will definitely try my best to serve you!

Pacific Automobile Network] The tire screws of the car are loosened in the counterclockwise direction: the left and right side of the tire screws of large trucks are not the same, the left (driver's seat) is the inverted tooth, and the right side is the straight tooth, that is, according to the forward rolling direction of the car is tightened, and the reverse direction is loosened.

The direction of the screws in the car tire change step.

1. The loosening of the tire screw of the car is counterclockwise: press the left hand in the direction of the center bend of the tire, and hold the wrench with the right hand and lift it up, and the screw will be loosened.

2. The left and right side directions of the tire screws of large trucks are different, the left (driver's seat) is the inverted tooth, and the right side is the straight tooth, that is, according to the forward rolling direction of the car, it is tightened, and the reverse direction is loosened.

3. Before changing the tire, before changing the tire, first park the car in a relatively safe and flat place. Then tighten the parking brake with the stop gear and turn the ignition to the "lock" position. Turn on the "double flash" and place a warning triangle far enough away from the car.

4. The second is to check the jack and the tool kit and spare tire carried with the car, usually, depending on the model, the spare tire is generally placed under the trunk floor, hanging under the tail of the car, and fixed outside the trunk door. Most of the spare tires of SUV (special area) models are hung under the tail of the car or fixed outside the trunk door, while the spare tires of the models mentioned in the article are placed under the trunk floor.

Summary. Hello.

As far as I know, underneath those screws next to the oil port of the Sylphy is the engine fan housing. The main role of this component is to provide better heat dissipation to the engine and help keep the engine temperature within the normal range. This part is usually connected to the engine by multiple screws and covered with the engine fan.

If you need to replace or repair this part, you will need to first remove all the screws around it and then remove it from the engine.

What's underneath those screws next to the oil port of the Sylphy machine.

Hello.

According to my understanding of the spring, under the screws next to the oil port of Xuanyi is the engine fan shell. The main role of this component is to provide better heat dissipation to the engine and help keep the engine temperature within the normal range. This part is usually connected to the engine by multiple screws and covered with the engine fan.

If you need to replace or repair this part, you need to remove all the screws around it first and then remove it from the engine.

In addition to the fan housing of the engine generator, some models will also install other parts here, such as generators, air conditioning compressors, etc. If you feel uncomfortable with this area or notice something unusual, it is best to find a professional to carry out a failure inspection and repair to ensure the safety and reliability of the car. Also, be sure to cut off the power to your vehicle and wait for the engine to cool down before operating to avoid injury.

It's from the hanger.

Why do you need to remove these screws?

Unload the engine or disassemble nearby parts.

The removal of the Sylphy crankshaft screw can be disassembled with special tools. The crankshaft is the most important part of the engine. It takes the force from the connecting rod and converts it into torque to sell through the crankshaft output and drive other accessories on the engine to work.

The crankshaft is subjected to the centrifugal force of the rotating mass, the gas inertia force of periodic change and the reciprocating inertia force, so that the crank bearing is subjected to the action of bending torsional load. The causes of crankshaft oil seal leakage are as follows:

1. The crankshaft oil seal does not use non-petroleum-based lubricants in the press-fitting process, resulting in the oil seal loosening or even falling off after the pure engine is used for a period of time, resulting in oil leakage from the rear oil seal;

2. The parallelism of the rear oil seal pressing surface for the rear oil seal seat installation surface does not meet the technical requirements of the assembly drawings, which makes the rear oil seal lip unevenly deformed, and the oil seal lip is deformed and even the entire oil seal is distorted after the engine is used for a period of time, resulting in oil seal damage and oil leakage;

3. The engine has a long service life, and cracks occur at the lip of the natural aging of the rear oil seal, resulting in oil leakage. The engine needs to be replaced in a timely manner.

First, check the exterior for oil leaks.

Pay special attention to the oil seals at the front and rear ends of the crankshaft for leakage of stool oil. Oil leakage at the front end of the crankshaft can be caused by broken or damaged oil seals at the front end of the crankshaft, aging or worn contact surfaces between the crankshaft pulley and the oil seal. The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cover is too small, and the oil return base is blocked, which will cause oil leakage at the rear end of the crankshaft.

In addition, attention should be paid to whether the rear end of the camshaft oil seal is leaking. The oil seal should be replaced in time if it is aging, broken and leaking. In addition, it is necessary to check whether there is leakage in each part of the engine lubrication system.

If there is oil leakage at the front and rear oil seals.

Even the front and rear cylinder head covers, front and rear valve lifter chambers, oil filters, oil pan gaskets and other organic oil seepage, but can not find obvious oil leakage, should check the crankcase ventilation device, clean the crankcase ventilation duct, especially check whether the PCV valve due to carbon deposition and gelation stagnation caused by poor work. Poor ventilation of the crankcase is likely to lead to an increase in pressure in the crankcase, resulting in multiple oil leaks.

If the joints of the oil filter and some oil lines are still leaking after being tightened, attention should be paid to check whether the oil pressure is too high and whether the oil pressure limiting valve is not working well.

Hello, what screws leak.
