What causes the high water temperature when the Jinbei Haise air conditioning is turned on?
2 Answers
This situation is mostly caused by a damaged thermostat. When the vehicle is driven at high speed, the heat dissipation increases and the water temperature decreases accordingly. At this time, the thermostat should gradually close to ensure that the water temperature does not continue to drop. If the thermostat does not close or does not close tightly, the water temperature will continue to drop, resulting in low water temperature. The issue of high water temperature at low speeds is also related to this problem. When the water temperature reaches the normal temperature, if the thermostat cannot fully open or the radiator surface is too dirty, leading to poor heat dissipation, it will cause high water temperature. Here is some additional information: 1. Introduction to Jinbei Haise: The Haise brand light passenger vehicle adopts manufacturing technology introduced from Toyota Motor Corporation of Japan, producing the RZH115L Haise series light passenger vehicles. Based on this, the SY6480 Haise series light passenger vehicles and various types of special-purpose vehicles, totaling over a hundred models, have been developed. 2. Advantages: Jinbei Haise emphasizes comfort, power, energy efficiency, and environmental protection. The interior is more car-like, equipped with a new-technology engine. The displacement is reduced, but the power is increased by nearly 20%, while being more fuel-efficient. One of the most significant changes in Jinbei Haise is the car-like interior, with 10 improvements in nearly 20 areas, making the interior design more beautiful and comfortable, and the functions more user-friendly, providing a refreshing experience.
From my experience driving the Jinbei Haise, the rise in water temperature after turning on the air conditioning is mainly because the compressor significantly increases the engine's workload when the AC system is operating. This forces the engine to handle more heat, and if the cooling system isn't efficient enough, problems can arise. Common causes include insufficient or degraded coolant, which fails to effectively lower temperatures; clogged radiator exteriors or interiors, where dust buildup blocks airflow; improper refrigerant charging in the AC system, leading to compressor overload and generating additional heat sources; as well as faulty radiator fans or loose belts, which impair cooling efficiency. It's recommended that owners first check the coolant's color and level to ensure it's within the normal range, and rinse the radiator surface with clean water to maintain cleanliness. If the fan operates abnormally or makes unusual noises, it should be replaced promptly. Running the AC for extended periods with high water temperatures is dangerous and could lead to engine overheating and failure, so it's crucial to have the issue diagnosed by a professional shop at the earliest sign of trouble.
