Reasons for frequent startup of an automotive electronic fan

Automotive electronic fan starts frequently,such phenomenon may result from wrong signals of an engine coolant temperature sensor that cause the engine control unit to believe that the engine coolant is too hot and to start the heat-dissipating fan for engine protection. Another possible reason is short circuit of the power supply circuit of the heat-dissipating fan. Since the fault detector on hand is unable to communicate with the car, it is not possible to directly read data from the engine coolant temperature sensor. Given that the engine failure indicator remains off and that the engine is cold started normally, the possibility of wrong signals from an engine coolant temperature sensor is … Read more…

What components are included in a steering gear assembly?

A steering gear assembly consists of steering gear, steering linkage, steering linkage outer ball head, and linkage dustproof cover. Also known as steering device or directional device, the steering gear assembly is the most important part in the steering system of a car. It serves to increase the force transmitted by the steering disc to the steering drive mechanism and to change the force transfer direction. Different types of steering gears: 1. A mechanical steering gear converts rotation of the steering disc into swing of steering rocker arm, and amplifies the torque at a certain transmission ratio; 2. Depending the specific transmission mode, a steering gear may take the form … Read more…

What are the differences between damper and shock absorber?

Damper is mainly used in electronic industry to reduce the amplitude of vibration waves. Dampers are classified based on their performance and purpose; Shock absorber is designed to suppress vibration of rebounding springs after shock absorption and impact from road surface. It is widely used on cars to achieve faster attenuation of car frame and body vibration and consequently smoother drives. When a car runs on bumpy roads, although the shock-absorbing springs dampen the road impact, they move reciprocally in this process. Shock absorber is intended to suppress such reciprocating motion; Given the vibration of elastic components in a suspension system under shock, in order to improve rider comfort, a … Read more…

Is it necessary to replace a 03L103469S valve chamber cover?

A 03L103469S valve chamber cover should be replaced in the following circumstances: 1. Aging of the valve chamber cover leads to poor sealing and consequent oil leakage through the valve chamber cover; 2. Higher pressure in the crankcase due to blocked forced ventilation valve results in depressurization via the valve chamber cover pad or other vulnerable parts and consequent oil leakage; 3. Over 90% cases of oil leakage through the valve chamber cover pad are caused by oil seal corrosion and aging. As the leaking oil flows into the ignition plug, the plug will contain a certain amount of oil. Name: valve chamber cover Ref No. : 03L103469S Product system: … Read more…

Possible reasons for water boiling in an auxiliary radiator

Possible reasons for water boiling in an auxiliary radiator: 1. Malfunction of a cooling fan or a broken fan belt impairs the heat dissipation function, causing the water in the radiator to become hotter and reach boiling point. 2. Leakage of the radiator results in less efficient cooling. As a consequence, the water in the radiator becomes hotter and reach boiling point. 3. Insufficient coolant in the radiator results in less efficient cooling. As a consequence, the water in the radiator becomes hotter and reach boiling point. Purpose of an automotive auxiliary radiator The auxiliary radiator is a supporting part for the water radiator, and serves as a key component … Read more…

Where is the front bumper cross beam located on a car?

The front bumper cross beam is the first cross beam behind the front bumper. Longitudinal and cross beams of a car: 1. A longitudinal beam is often produced with low alloy steel sheets by means of punching, with a typical grooved cross section. Some have a Z-shape or box-shape cross section; 2. Depending on different automobile types and structures, a longitudinal beam can be bent along a horizontal or vertical plane, and may have a uniform or non-uniform cross section; 3. A cross beam not only provides required torsion rigidity for the frame and bears longitudinal load, but also supports main components of the car. Name: front cross beam Ref … Read more…

symptoms of water shortage in a vika automobile radiator

1. In the case of water shortage in a vika automobile radiator, a corresponding indicator light on the dashboard will go on to alert the driver. After the engine hood is opened, a cooling water expansion tank can be found. This tank is marked with a lower limit line and a higher limit line. If the water drops below the lower limit line, it is insufficient. 2. A water-cooled engine is used on modern cars, and surplus heat is taken away by circulating coolant. The coolant used for a water-cooled engine is of anti-freezing type, commonly known as the antifreeze. It prevents freezing in cold winter days. Once frozen, water … Read more…
