Where is 06D117021C oil cooler installed on a car?

The 06D117021C oil cooler is typically installed near the radiator. In some cases, an oil cooler may be placed next to the pipe connected to the oil filter element base. On some models, the water jacket in the engine is used for heat dissipation. 1. Oil cooler is a device intended for accelerating heat dissipation of lubricant oil and preventing it from becoming hot; 2. For powerful engines with high performance and high power, an oil cooler is required due to heavy thermal load; 3. The oil cooler is arranged in the lubricant oil circuit, and works on the same principle as radiator. Name: oil cooler Ref No. : 06D117021C … Read more…

Basic functions of engine mounting system and technical requirements

An engine mounting system serves two basic functions: supporting the engine and isolating its vibration. The exciting force generated during engine operation consists of two parts: The first part results from the pulse pressure in the cylinders due to non-uniform engine ignition and engine operation in unbalanced status. The second part is vibration excitation caused by bumpy road. The vibration of certain order at natural frequency may be significant in amplitude and generate large noise. The power assembly mounting system serves as the connection between the engine and the vehicle body, providing the main function of attenuating large low-frequency vibration of the engine and suppressing high-frequency noise in the driver’s … Read more…

How to deal with a leaky 038103603N oil sump?

Solutions to a leaky 038103603N oil sump: 1. If oil leakage occurs at the oil sump after replacement of engine oil, the fault may result from too low viscosity of the oil due to deviation of the new oil from specification of standard oil for the car. 2. Since excessive oil may also cause leakage, make sure that the amount of oil is within the normal range as indicated by the scale mark during refilling. 3. The oil drainage screw of the oil sump may have become loose or damaged. The gasket used in conjunction with the oil drainage screw serves a sealing purpose as well, and should be replaced … Read more…

What are the symptoms of a broken 03F145749C intercooler?

Common symptoms of a broken 03F145749C intercooler on a car include power degradation, higher fuel consumption, black exhaust smoke, serious wear of engine cylinder, and heavy carbon deposition on the engine. If the intercooler experiences any problem, it must be inspected and repaired in time so that it won’t interfere with normal functions of the car. As a supporting part for a turbocharging system, the intercooler only appears on models equipped with a turbo-supercharged engine. The intercooler cools down gas after supercharging and consequently leads to lower engine load. It also helps increase the amount of air inflow and engine power. Depending on composition material, intercoolers are typically divided into … Read more…

What are the consequences of leakage of a valve chamber cover?

03L103469R valve chamber cover, also known as valve chamber cover, is a sealing part on top of an engine. Working in conjunction with an oil sump, it seals engine lubricant, and prevents it from leaking out during engine operation. Equipped with an air valve, a cylinder cover forms a closed compression chamber together with the cylinder block. Combustible air mixture is burned in this chamber under certain conditions. The parts concerned are valve chamber cover, cylinder cover, cylinder block, and oil sump from top to bottom. Consequences of leakage of a valve chamber cover: 1. Leakage of a valve chamber cover may cause the car to lose power or fail … Read more…

What is the structure of a 5Q1819021A fan on a car?

As the term suggest, 5Q1819021A fan is installed in an automotive air conditioning system for transferring clean air. It is a key device in the air conditioning system, and plays a crucial role for air circulation in the car. Fan structure: Impeller: with an involute profile and a high volume utilization rate. Synchronizing gear: consisting of gear ring and hub for easy adjustment of impeller clearance. Base: A common base is adopted for small and medium fans. For large fans, only a fan base is provided for easy installation and commissioning. Body: The body structure is comprised of enclosure and left and right wall plates. The left and right wall … Read more…

What is the purpose of 6Q2423055RX steering gear assembly?

6Q2423055RX Steering gear assembly is a key assembly in the steering system of a car. It provides three main functions. First, it augments the torque generated by the steering wheel to a level sufficient for overcoming the steering resistance torque between the turning wheels and the road surface; Second, it reduces the RPM of the steering drive shaft and causes the steering rocker shaft to rotate, driving the rocker arm to swing and allowing its end to obtain desired displacement. Or alternatively, it converts rotation of the driving gear connected to the steering drive shaft into linear gear-rack movement, thus achieving desired displacement; Third, by selecting different threaded directions on … Read more…

What are the symptoms of a broken 6Q0498099D ball cage?

The following symptoms may appear if a 6Q0498099D ball cage on a car fails: 1. Regular clatter sounds can be heard when the car turns or runs on bumpy roads, and loss of power may occur in serious cases. If clear clatter sounds are generated during turns, the external ball cage is probably broken. In rare cases, the symptom may be caused by a failed internal ball cage; 2. If clatter sounds are generated on bumpy roads, there is a strong possibility that the internal ball cage has failed. Such failure may also lead to noise when the car runs straightly. In most cases, the sounds are only heard in … Read more…

How to repair a failed 1J0513025BG shock absorber?

After discovering a problematic or failed 1J0513025BG shock absorber, first check if it has exhibited any old or new signs of oil leakage. In the event of a broken oil seal or seal washer or loose screws of an oil tank, the failed oil seal or seal washer should be replaced. If oil leakage persists, the shock absorber should be pulled out. If the absorber fails to move smoothly or the load changes in this process, check if the gap between the piston and the cylinder is excessive, if the connection rod of the shock absorber piston has been bent, and if there is any scratch or pull mark on … Read more…

What is the main purpose of 6R0121253 radiator?

6R0121253 Radiator is a main part in the cooling system of a car. It is designed for heat dissipation. The cooling water absorbs heat in the water jacket, dissipates it through air, and then returns to the water jacket. This process takes place cyclically for the purpose of heat radiation and temperature adjustment. The radiator is also a key part of the automotive engine system. An automotive radiator mainly consists of radiator body, water pipes, heat dissipation air vanes, upper water tank, and lower tank. The upper water tank is located above the radiator, and connected by water pipes to the lower tank under the radiator. Hot water becomes warm … Read more…
