'

Engine coolant heater, also known as engine block heater, is an electric heating device installed on vehicles for preheating the engine and facilitating the engine to reach normal working temperature more quickly. By preheating the engine, engine coolant heater can improve the cold start performance of the engine and keep the engine at the desired temperature.

In general, engine coolant heater should be installed close to the engine block. It needs to be connected to the cooling system internal belt of the engine and requires a certain electricity supply. After installation and power on, it can automatically heat the engine coolant, so that the engine can quickly reach the normal working temperature.

Generally, engine coolant heater can be used in bad weather conditions or cold areas where car owners need to start a car in a short time. When the engine is cold, a longer engine start-up time is usually required, which may cause incomplete combustion, incomplete burning fuel and other phenomena, which affects the engine and exhausts the exhaust gas. After installing engine coolant heater, the cold start of engine and the combustion of fuel can be completed in a short time, which can reduce the fuel consumption, reduce the emission of harmful gases and protect the engine.

Therefore, engine coolant heater is an accessory that can improve the performance and save fuel for modern cars. It can be used in cold areas to reduce engine wear and tear caused by cold start and reduce fuel consumption.
