What are symptoms of a broken rear suspension rubber bushing?

Symptoms of a broken rear suspension rubber bushing: 1. Clanging metal sound can be heard when the car runs on a speed bump, flagstone road, or a dirt road. 2. Noise may persist while driving on fairly bumpy roads. 3. In very serious cases, small vibration can be transmitted to the steering wheel continuously. In sum, the car will generate abnormal sound depending on various road conditions. The “hard” connections between the suspension and other metal parts rely on the rubber bushing to cushion vibration between metal and the resulting noise. An aged bushing may be unable to absorb shock, and consequently noise can be generated by colliding metal parts. … Read more…

What are consequences of deformation of the steering knuckle?

Deformation of the steering knuckle on a car can cause the steering wheel to jitter during drives. The steering knuckle is designed to bear and transmit load in the frontal part of the car. By supporting the front wheels and driving their rotation around the wheel pin, it enables turning of the car. While on the road, it is subject to varying impact load. High strength is therefore required to ensure normal function. Symptoms of a bent steering knuckle arm include the following: 1. Deformation of steering knuckle arm The deformation may result from insufficient lubrication or damage of the steering knuckle thrust bearing, or from too small gap between … Read more…

Why does water come out of the expansion tank after the engine is shut off?

The expansion tank is a critical part in the heat dissipation circuit of a water-cooled engine, and serves the purpose of balancing pressure of the radiator. It works on the following principle: When the engine radiator absorbs heat from the cylinder and becomes hotter, the liquid will expand and result in higher pressure. The coolant in the radiator will flow via a bidirectional valve and the radiator cover to the expansion tank. When the temperature drops and the pressure of the cooling system becomes negative, the system will suck the coolant from expansion tank via the radiator cover back to the radiator. In this way, it maintains a balance of … Read more…

What are the differences between intercooler and vika radiator?

Intercooler and vika radiator serve different purposes. An intercooler is used to lower the intake air temperature of an engine. It helps reduce thermal load of the engine while increasing the amount of intake air. A radiator serves as the cooling unit for an engine, and is used to dissipate unnecessary heat from the engine (by water cooling). On a car with a supercharged engine, the intercooler acts as a cooling device for intake air. It is typically only found on models equipped with a pressure charger. The intercooler decreases the intake air temperature of the engine. It helps reduce thermal load of the engine while increasing the amount of … Read more…

Purpose of 5N0965561A auxiliary electronic pump

Main purpose of 5N0965561A auxiliary electronic pump: Even after the engine is shut down, the electronic coolant pump is able to run to maintain coolant recirculation and cool down the supercharger completely. It works on the following principle: Under electric control of the engine control unit (ECU), the pump helps with cooling of the turbocharger in certain working conditions. After shutdown of the engine, the auxiliary electronic pump dissipates heat from the turbocharger. During drives, the engine control unit provides automatic adjustment depending on different conditions to prevent damage to the turbocharger due to excessive heat. After the engine is turned off after long operation at high speed, this coolant … Read more…

What it the rain & fog mode of skoda headlight?

Rain & fog mode of skoda headlight: 1. Better illumination effect in fogy days is achieved by increasing the brightness of LED units, using a lower irradiation angle, and adjusting the range of scattered illumination; 2. Since front fog lamps are no longer used on many models, in order to deal with harsh weather conditions such as rain and fog, a rain & fog mode is made available on some models; 3. Turning on this function will extend the illumination range of headlights and reduce glare due to reflection by rain and fog. The rain & fog mode is intended to act in place of normal function of headlights, and … Read more…

Symptoms and causes of a broken vika engine oil pump

Early-stage symptoms of a broken vika engine oil pump: 1. Harsh sound is heard from the engine. 2. The engine failure indicator goes on. 3. Heavy smoke is drained from the exhaust pipe. 4. The oil pressure gauge exhibits a too low reading. 5. The engine jitters violently. 6. The engine is hard to start, and the key needs to be pressed for long during startup. The engine oil pump serves to transfer engine oil from the oil sump to different pipes in the oil circuit (for cooling) and oil filters (for oil filtering) by means of pressurization. It also lubricates the cylinders to ensure smooth and normal engine operation. … Read more…

What are symptoms of a broken vika rear axle?

A broken vika rear axle on a car may exhibit the following symptoms: 1. Abnormal sound during drives, such as clanking sound from the rear axle (differential bearing shell). The sound may disappear when the neutral gear is engaged. This phenomenon may result from a damaged gear or a broken connection bolt. In this case, pull over the car and contact road rescue for repair. Have the damaged part replaced before hitting the road again; 2. If the car roars like an aircraft during drives, especially in 1-2 seconds after fuel loss, the symptom is most likely caused by a worn driving gear or driven gear, which should be repaired … Read more…

How to determine if a water spraying motor has failed?

In order to determine if a water spraying motor has failed, we should check if the wiper blades can move normally. If they move without water sprayed, the water spraying motor may be broken, or something may be wrong with the circuit. Further examination is required to determine the specific cause. The common causes include insufficient windshield washer fluid, leaky water pipe, blocked filter screen, blocked water nozzle, damaged water spraying motor, or a circuit fault. The engine hood needs to be lifted for inspection: Solutions: 1. Replace the wiper blade relay. If the wiper blades are not able to work at intermittent (INT) and reset positions, but function normally … Read more…

What is 6RU423810 steering tie rod?-auto parts

6RU423810 Steering tie rod typically refers to a steering system part fixed together with the front shock absorber in a car. A steering straight rod on a car is connected to the pull arm of the steering gear and the left knuckle arm. It is intended to maintain synchronous operation of two wheels under control and for toe adjustment. Steering tie rod is a key component in an automotive steering system. It has a direct bearing on control stability, operation safety factor, and tyre service life of a car. There are two common types of steering rod: steering straight rod and steering tie rod. The steering straight rod is mainly … Read more…
