Automatic Transmission Torque Converter: Everything About the Device and Its Failures

The torque converter is by no means a new invention in the automotive industry. It first appeared nearly a hundred years ago, and over the decades, its design has undergone significant changes. Today, torque converters are used to transfer torque in many industrial sectors — and, of course, the automotive industry is no exception. In this article from Avto.pro, you’ll learn about the structure of torque converters, their working principles, and common malfunctions.

Brake Fluid Leak — Main Causes and Solutions

The braking system in modern vehicles is known for its high reliability. Some of its components — such as brake pads and discs — are considered consumables. They don’t last as long as many drivers would like, but their replacement is relatively simple and inexpensive. Brake fluid is also considered a consumable. Previously, Avto.pro covered how to choose the right brake fluid — you can learn more in that article. Today, we’ll discuss the issue of brake fluid leaks. Is it safe to continue driving with a minor leak? What is the optimal fluid level? What should a driver do after detecting a leak? Find out more below.

NOx Sensor: Purpose, Design, and Malfunctions

Drivers are no longer surprised that vehicles are constantly being modernized. Many technical solutions commonly found in modern passenger cars were actually developed back in the 1990s — a time full of innovation in the automotive industry. However, there are still plenty of systems that many car owners may not be aware of. One of these is the NOx sensor — also known as the nitrogen oxide sensor or lean mixture sensor. More and more vehicles today are equipped with these devices due to increasing environmental standards. In this article from Avto.pro, you’ll learn about the design, key features, and common failures of NOx sensors.

Starter Solenoid: Common Failures and How to Choose a New One

In cold weather, it’s not uncommon to hear just the sound of the starter or some of its components when trying to start the engine. Replacing the entire starter might solve the issue, but in many cases, the problem lies in just two components — the Bendix gear or the starter solenoid. The starter solenoid is a device that helps start the internal combustion engine by transmitting an electric signal to the starter. It usually consists of an electromagnet, contact points, and springs that work together to engage the starter motor. In this article, we’ll focus on this component and answer questions such as: how to test a solenoid, how to repair it, and how to choose a new one if needed.
