What is the purpose of vika coolant thermostat?

Any liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. Its job is to block the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions.

How to fix a broken door lock on a car? _ Auto Parts

A car door lock failure usually involves the central control door lock module, and should be preferably repaired at a 4S shop. The failure cause can be quickly identified with a detector. The repair cost depends on the car model and the specific type of the door lock module. The central control door lock is designed to facilitate safe use of the car. It can centrally control locking, closing, and opening of the four doors. The central control door lock works on a principle that converts electricity into mechanical energy, and opens/closes the doors through rotation of gears driven by a motor. It generally consists of door lock switch, door … Read more…

What is the purpose of 03L115389H oil cooler?

03L115389H Oil cooler is designed to cool lubricant oil and control its temperature within a normal working range. An oil cooler is necessary for high-power engines due to high thermal load. During engine operations, as the temperature increases, the oil grows thinner with lower viscosity, and the lubrication performance degrades accordingly. For this reason, an oil cooler is mounted on some engines to cool the oil and maintain certain viscosity. The oil cooler is arranged on circulation oil pipelines in the lubrication system, and works on the same principle as radiator. Name: oil cooler assembly Reference OE number: 03L115389H Product system: engine Brand: vika Applicable models of 03L115389H oil cooler: … Read more…

What is the working principle of 032121111CL thermostat?

The most common 032121111CL thermostat is of wax type. When the coolant temperature drops below the specified level, the refined paraffin wax in temperature-sensing body of the thermostat will be in a solid state. Under the action of a spring, the thermostat valve closes the channel between the engine and the radiator. The coolant will flow back via the water pump to the engine for small circulation in the engine. When the coolant temperature reaches a certain level, the wax will begin to thaw and become liquid, expanding and forcing the rubber pipe to shrink. In the meanwhile, an upward thrust will be applied to the push rod, and the … Read more…

What are the symptoms of a broken water pump on a car?

1. Unstable idle ignition Connected to a transmission belt, the water pump draws cold water from a water tank and feeds it to the engine for the purpose of cooling. A broken water pump can directly affect the rotation resistance, causing the engine’s transmission ratio to vary after ignition and leading to instability. In the case of excessive resistance (typically in winter), the engine may flame out. 2. leakage The most common leakage involves coolant liquid, and some water can be found at the vent of the water pump. Coolant liquid is intended to solve the problem of water boiling during high-speed operation of the engine. In the event of … Read more…

What are possible reasons for a failed steering gear?

1. Abnormal sound of the steering gear Popping sound can be heard during drives, especially when turning the steering wheel. This symptom may point to a broken steering gear. The abnormal sound of the steering gear may be attributable to many factors, among which a failure of power steering oil, universal joint, or plane bearing is most common. Such abnormal sound is a distinctive sign of failure. Therefore, once it occurs, the car should be sent to a 4S shop for repair immediately. 2. Direction jitter or deviation: If the car deviates significantly from straight paths on the road, external factors should be first checked and eliminated. If the problem … Read more…

How to maintain air filter elements? – Auto Parts

1. Filter element is the core part of a filter. It is made of special materials and easy to wear. Special maintenance and servicing are therefore required for filter elements; 2. After a filter is used for an extended period, a certain quantity of impurities has been retained by the filter element, leading to higher pressure and lower flow. The filter element should be cleaned in time in this case; 3. While cleaning a filter element, caution should be exercised to avoid deformation or damage. The service life of a filter element is generally dependent on the raw material used. Since the impurities in the air can block it after … Read more…

What is the difference between caliper and brake block?

The difference between caliper and brake block can be summarized as follows: In a braking sequence, the brake block is pressed onto the brake disc or brake drum to generate friction that decelerates the car, whereas the caliper holds the brake disc tightly to decelerate or stop the car. Since brake caliper and brake block are terminal actuators in the braking system, proper retrofit of these two parts can lead to immediate improvement of braking force. Retrofit of brake caliper: Changing an existing brake caliper into a larger multi-piston one can improve braking performance directly. A larger brake caliper means larger total area of the matching brake block. The increase … Read more…

What are the symptoms of knuckle failures?

Symptoms of knuckle failures: 1. During a drive at medium or high speed, periodic sound is heard from the chassis. In serious cases, the driver’s cab and doors jitter, and the steering wheel vibrates violently and even causes numbness of hands. Such symptoms result from loss of direction balance of the transmission due to excessive wear of the transmission shaft and its spline shaft and spline housing; 2. Too tight engagement between rolling bearings and sliding bearings in different parts of the steering system, poorly lubricated bearings, too tight steering tie rod or cross beam ball head, or lack of oil may cause the steering shaft and its enclosure to … Read more…
