What causes the high water temperature in Zhonghua Junjie FRV?
2 Answers
Zhonghua Junjie FRV's high water temperature may be due to a problem with the water circulation. Here is an introduction about the radiator: 1. Concept: The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function 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. It is a part of the car engine. 2. Working principle: The radiator is an important component of a water-cooled engine. As a crucial part of the cooling circuit, it absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, the temperature rise after absorbing the engine block's heat is not significant, so the engine's heat is dissipated through the liquid circuit of the coolant.
Once when I was driving my Zhonghua Junjie FRV on a long trip, the water temperature was running high, which really scared me. Later, it was found to be caused by insufficient coolant due to leakage. The car's cooling system is complex. If the thermostat gets stuck in the closed position, it will cause the coolant to circulate only in a small loop, leading to poor heat dissipation. Worn-out water pumps also affect cooling efficiency. If the radiator is clogged with dust or the water tank is scaled, heat dissipation deteriorates. Also, if the fan doesn't turn on or fails to start, it might be due to a faulty relay or sensor issues. Environmental factors like hot weather or traffic jams increase engine load, making it easier for the temperature to spike. It's recommended to pull over immediately, check the coolant level, and add pure water as a temporary solution. For long-term maintenance, regularly service the system, replace the coolant, and clean the system to avoid engine overheating and cylinder scoring.
