Hello,
Does anyone know where i can find the thermostat shown in the picture?
I already have a new one with the correct part number but this rubber is missing and it seems that is fixed on thermostat cannot be removed.
Thank you

Chongqing Feilong Jiang Li has an independent rubber and plastic workshop, which mainly produces body rubber products, such as bushings, sealing rings and so on. In order to better realize the process and satisfy the design concept, and to ensure the bushing in normal working state more effectively in the process of vehicle assembly, Chongqing Feilong Jiang Li will choose a suitable reference point as the initial zero angle of rubber bushing, which is regarded as the best working state of bushing. In order to keep the best working condition as long as possible, Feilong Jiangli will choose the most common working condition of the whole vehicle as the initial zero angle of the village set. Generally speaking, it is considered that the normal working condition of a car is no-load or half-load, that is to say, the landing state. The corresponding bushing assembly process at this time is called landing tightening technology, that is, tightening the rubber bushing after the vehicle landing. Feilongjiangli's rubber bushing is processed by ingredient, stamping and injection moulding. Each process has strict quality control procedures. The finished bushing is mainly used on Chang'an CS35 and CS75 models.

Alloy steel refers to the steel grade formed by purposefully adding one or more alloy elements on the basis of carbon steel in order to improve some properties of steel.
Alloying elements have great influence on the properties of steel. For example, adding chromium into carbon steel can improve the strength, hardness and corrosion resistance of steel. Adding nickel can not only improve the strength of steel, but also reduce its toughness. Adding silicon can improve the strength, hardness, fatigue strength and corrosion resistance of steel. The simultaneous use of several alloying elements has a more significant effect on the properties of steel than a single alloy element.
Only after heat treatment can the alloy steel achieve the purpose of improving its mechanical properties.
There are many kinds of alloy steels, which can be roughly divided into the following categories according to their uses: alloy structural steels, alloy tool steels, special performance steels.
Alloy structural steels include low alloy structural steels, alloy carburizing steels and alloy quenched and tempered steels.
Low-alloy structural steels: steels based on low-carbon steels with a small amount of alloy elements (3% - 5%); these steels have a strength of 10% - 30% higher than carbon steels with the same carbon content, and have good plasticity, toughness and weldability. Because of its simplicity in smelting, its production cost is similar to that of carbon steel, it is widely used to make various machine parts and engineering components, such as frame longitudinal beam, cross beam, engine lug, etc., and substituting low alloy structural steel for carbon structural steel can save steel, reduce weight and use reliably. Commonly used steel species are 12MnV, 16Mn and so on.
Alloy carburized steel: parts made of alloy carburized steel, after heat treatment, not only have higher surface hardness and wear resistance, but also can greatly improve the strength and toughness of the center of the parts, thereby improving the ability to resist impact loads; automotive parts withstand high speed, heavy load, strong impact and severe friction, such as piston pins, gears, shafts Parts and important bolts are made of alloy carburized steel after heat treatment.
Alloy quenched and tempered steel: Alloy quenched and tempered steel refers to the steel used after quenched and tempered, with high strength and toughness. If quenched and tempered and then quenched, the wear resistance of parts surface can be improved. It is often used to manufacture parts bearing heavy load and impact load. Such as machine tool spindle, automobile half shaft, connecting rod, steering knuckle, etc.
Other alloy steels and special performance steels: commonly used steel alloy spring steel, rolling bearing steel, alloy tool steel, weathering steel (good atmospheric corrosion resistance), stainless steel, wear-resistant steel, heat-resistant steel.

OEM vs. Aftermarket Parts for Your Car: How to Choose
APF posted a topic in General Auto Parts Discussion,
When selecting parts for a car repair, it pays to know the differences between original and aftermarket parts. Whenever possible, get estimates for both.
Choosing between original and aftermarket car parts — and even used parts of either type — is all about squaring your priorities with your budget.
You’ll have different options depending on the part and the shop. And the best choice will depend on whether you’re trying to keep repairs cheap, restore your car’s appearance after a wreck or soup up your ride.
Original equipment manufacturer (OEM) parts match those that came with your car, and are of the same quality as its original parts. They’re also the most expensive.-

Replacement Intervals For Oil And Air Filters In Today’s Vehicles
APF posted a topic in Automotive Wipers, Filters, Oil & Lubricants,
The factory-recommended replacement intervals for filters can vary quite a bit depending on the year, make and model of the vehicle, as well as how it is driven. As a rule, older vehicles (those more than 15 to 20 years old) typically have more frequent service intervals than newer vehicles. Why? Because late-model vehicles require less maintenance, thanks to improvements in motor oils, transmission fluids, engine design and filter media.
Many long-life air and oil filters use synthetic fiber media or a blend of cellulose and synthetic fibers to extend filter life.
Changing the oil and filter every 3,000 miles was standard practice decades ago. But it’s no longer necessary because most multi-viscosity oils today are a synthetic blend or a full synthetic that resist viscosity breakdown and oxidation for a much longer period of time. Late-model fuel-injected engines also run much cleaner than their carbureted ancestors, which reduces oil contamination in the crankcase.-
