Repair and Maintenance UAZ 3163 (Patriot)

UAZ Patriot This is a comfortable modern SUV that has embodied all the best developments and technical solutions of UAZ specialists over the past 10 years. And no wonder, because the UAZ Patriot, the serial production of which began at the Ulyanovsk Automobile Plant on August 17, 2005, is the first fundamentally new model SUV developed at UAZ over the past 30 years. This car is aimed at people who lead an active lifestyle, and is perfect for daily trips around the city for shopping or to work, and for recreation outside the city limits, in nature.

From fundamentally new solutions of specialists Ulyanovsk Automobile Plant It is worth noting the design of the suspension, steering and transmission assemblies, the interior, which is characterized by increased convenience, and a very attractive, original exterior design. Imported components are widely used in the assembly of UAZ Patriot vehicles, their share in the car is more than 20 percent. Special mention should be made of the Iranian panel, the Korean gearbox like the one on the Rexton, and the headlights that Bosh designed specifically for the UAZ Patriot.

In order to successfully implement the launch of the production of a novelty, to achieve high quality indicators of car assembly at the Ulyanovsk Automobile Plant, a new welding line was launched, the main conveyor was modernized, and new complex for painting Eisenmann. The introduction of a new " Production system", similar to that used in Japanese car factories, and the personnel undergoing a special training course for assembling Patriot. All this testifies to the special attitude of the enterprise leaders to this model, and it, it should be noted, has borne fruit: the build quality in comparison with the previous models of the plant. At the first entry into the salon of a new UAZ model, one immediately draws attention to the thoroughness of the study of everything, down to the smallest details. The salon is spacious and comfortable, the interior is trimmed with practical soft plastic. the tilt angle regulator will allow even a very tall driver to drive the car as conveniently as possible.In the harsh Russian winter, the stove saves from the cold, which in the new model can also work separately for the first and second rows.

Fortunately, the comfort did not compromise the dynamic performance, excellent endurance and flotation of the Patriot. One has only to turn on four-wheel drive, and you will feel like a tamer of even the most impassable spaces. The main components of the car do not fail even in extreme conditions, and the high-spirited engine allows the UAZ Patriot to accelerate to a speed of 150 km / h.

Summing up, the advantages of the new UAZ SUV can be considered a spacious and comfortable lounge with a modern design, excellent visibility, comfortable seats and, of course, cheapness compared to imported counterparts. The disadvantages include modest dynamics, itching and vibration of the levers, cotton brakes, limited traction, blurry reaction on the road.

The basic configuration of the UAZ Patriot includes central locking, power steering, adjustable steering column, audio preparation, additional brake light on back door as well as stamped wheel disks with tires 225/75 R16. In the Comfort version, an electric drive, electric heating, front electric windows and a few more additional options are also installed.

Classic model

The off-road vehicle UAZ 3163 Patriot was put into production at the Ulyanovsk Automobile Plant in 2005. It became the successor to the UAZ 3160 and, which appeared in 1997 and 2000, respectively. Its main difference from previous models was the use of a large number of imported parts.

UAZ Patriot is equipped with European steering, braking, heating and air conditioning systems. In addition, the car has a Dymos gearbox (gearbox) and comfortable seats manufactured by the South Korean corporation DAWNSCO.

Some machines were equipped with imported diesel engine Iveco F1A, but it was subsequently replaced by the domestic motor ZMZ 51432 meeting higher environmental standards. All other details, including chassis, transfer case and axles remained domestic.

Thanks to the modernization, UAZ repairs on their own began to be required much less often. Despite this, the need for regular maintenance of the Patriot remains, since it is very difficult to find a reliable UAZ car service.
