The difference between an intercooler and a water tank, and the function of an intercooler

To cool down the engine, a cooling device is essential. However, today we'll discuss the difference between an intercooler and a radiator, as some may still be unclear about their distinctions. To better understand, let's introduce their respective functions below.

An automotive intercooler is an intake air cooling device for turbocharged engines; it's only found in vehicles equipped with a turbocharger. Its function is to lower the engine's intake air temperature, which not only reduces the engine's thermal load but also increases the intake air volume, significantly improving engine power. Don't underestimate its importance; the exhaust gas temperature from a turbocharged engine is extremely high. If it enters the combustion chamber without cooling, it can easily cause the engine temperature to become too high, leading to knocking and increased exhaust emissions.

An automotive radiator, also known as a heat sink, is a major component in the vehicle's cooling system, used to dissipate excess heat from the (water-cooled) engine. When the system detects that the engine temperature is too high, the water pump circulates water repeatedly to lower the engine temperature, effectively protecting the engine. Conversely, when the temperature is too low, the water circulation stops to prevent the engine from becoming too cold.

The intake manifold provides a relatively sealed passage for air or combustible mixture entering the engine. A sensor that measures the engine's intake air volume is usually installed on the intake manifold. Engine intake manifold inspection
The intake manifold provides a relatively sealed passage for air or combustible mixture entering the engine. A sensor that measures the engine's intake air volume is usually installed on the intake manifold.
After prolonged use, the plastic intake manifold may age and crack, causing inaccurate measurement of the engine's intake air volume, unstable idling, or reduced acceleration performance. If the intake manifold is blocked by foreign objects, the engine's intake air volume will decrease, reducing engine power output. Therefore, it is necessary to inspect the intake manifold and perform appropriate maintenance.
