What Causes the Engine Temperature to Rise by One Bar When Driving on the Highway?

[VonCassandra]

When the car's engine temperature rises by one bar while driving on the highway, the possible cause could be a faulty thermostat leading to insufficient opening, resulting in poor coolant circulation. Here is more information about the car radiator: 1. Introduction: The car radiator, also known as the heat exchanger, is a key component of the car's cooling system and part of the engine assembly. 2. Function: Its purpose is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket for circulation, achieving temperature regulation. 3. Working Principle: When the engine's temperature is high, the water pump circulates the coolant repeatedly to lower the engine's temperature and protect it. In winter, if the coolant temperature is too low, the circulation stops to prevent the engine from becoming too cold.
