Engine coolant in a car - tips for care and replacement!
Modern cars need water cooling. Otherwise, high-performance engines would not be able to maintain optimal operating temperatures. Defects in the cooling system quickly lead to serious engine damage. But also the wrong coolant can damage the engine from the inside. Read in this article what to observe regarding the coolant of your car's engine. What causes the engine to heat up? Engine heat is generated in two ways: by fuel combustion and by internal friction. In the combustion chambers of the engine, the fuel is brought to an explosion at a temperature of several hundred degrees Celsius. Metal is an adequate conductor of heat. Since the entire engine is made of metal, the heat from the combustion chambers is distributed throughout the unit. In addition, the engine consists of several hundred moving parts. Although they are always lubricated, there is a certain amount of internal friction that causes…

New car radio not working - now what?
It all sounds so simple: car radios are equipped with standard connectors that allow you to connect them to the car's speakers and power supply. In case of incompatibility, a suitable adapter allows you to connect, at least in theory, as practice sometimes shows otherwise. Simple Basic Principle A car radio is an electronic component that obeys all the laws of physics, just like all other electrical parts. Electronic components are also referred to as "consumers". These could be lamps, heated seats, auxiliary motors (power windows), or an audio system in a car. The basic principle of electronics is that current always flows through circuits. Each consumer of electricity must be installed in a closed circuit. It consists of a positive and negative power supply and auxiliary cables. Simply put, all cables leading to the consumer are outgoing cables, and all wires ...
Car Rust Fight - Brown Pest Fight!
Automotive history and car rust go hand in hand. All of the century-long research into rust protection, preventive measures and attempts to control gnaws have failed to solve the problem. Sooner or later, all steel and iron components of the car begin to corrode. However, with some care, you, as a car owner and driver, have a good chance of significantly delaying the death of your car due to corrosion. How does rust appear on a car? Steel is mined from iron ore, which is nothing more than oxidized iron. By adding a reducing agent (usually carbon) and energy (heating), oxygen is removed from the iron oxide. Now iron as a metal can be processed. In nature, it occurs only in the form of iron oxide and therefore constantly reacts ...
