What Causes High Water Temperature When the Air Conditioning is On in Wuling Hongguang?
2 Answers
High water temperature may be due to excessive dirt on the radiator surface, which affects heat dissipation. If the water temperature is too high, cleaning the dirt on the radiator surface can help lower the temperature. If the coolant hasn't been replaced for a long time, it is recommended to replace it, as prolonged use can cause the coolant's freezing point to rise. Below are some relevant introductions about the Wuling Hongguang: 1. Introduction One: The Wuling Hongguang features a trendy double-U front face design and a vertical chrome-plated grille, making the front look more stylish and dynamic while inheriting some characteristics of the General Motors series. 2. Introduction Two: The interior of the Wuling Hongguang adopts a car-like design style. The dashboard is simple and clear, with a well-laid-out control panel that is easy to reach. The combination of black upper and light lower tones, along with the wraparound cockpit design, enhances the home-like atmosphere and friendliness. 3. Introduction Three: The Wuling Hongguang is equipped with two engines: the P-TEC 1.2L and the 1.5L-DVVT, both designed and manufactured according to General Motors' global powertrain standards. These engines feature a double overhead camshaft design, which is relatively rare in small-displacement engines, ensuring ample power while also demonstrating good fuel economy, significantly reducing vehicle operating costs. 4. Introduction Four: The Wuling Hongguang uses a five-link swing-arm rear suspension with excellent shock absorption. The drivetrain adopts a front-engine, rear-wheel-drive layout, with a 45:55 front-to-rear axle load distribution, ensuring a reasonable center of gravity and relatively balanced traction across all four wheels, providing better performance when climbing slopes.
Over the years of running my auto repair shop, I've seen numerous cases of Wuling Hongguang overheating, especially when the AC is turned on—it's a real headache. There are several main reasons: First, the cooling fan is often the main culprit. When the AC is turned on, the compressor kicks in, increasing the engine load and generating more heat. If the fan's thermostat switch is faulty, the relay has poor contact, or the motor is burnt out, insufficient airflow leads to overheating. Second, radiator blockage is very common—dust, bugs, and fluff clogging the radiator fins in summer restrict airflow and hinder cooling. Third, a failing cooling system, such as low, aged, or leaking coolant, reduces circulation efficiency and prevents proper heat dissipation. Fourth, if the water pump leaks or runs too slowly, coolant circulation weakens, making it hard to disperse heat. I advise owners to promptly check if the fan runs properly, clean the radiator, ensure fresh and sufficient coolant, and fix any leaks immediately. Regular maintenance can prevent 90% of these issues; otherwise, engine overheating may lead to costly repairs or even total failure.
