What Causes the Wuling Zhiguang's Radiator to Frequently Boil Over?
1 Answers
The frequent boiling over of the Wuling Zhiguang's radiator may be caused by several factors, including a faulty engine thermostat that fails to open, insufficient coolant, a malfunctioning engine water pump, a clogged radiator, or a non-functioning cooling fan. It is recommended to visit a 4S shop or an auto repair shop to diagnose the specific issue. The detailed reasons are as follows: Reduced Heat Exchange Efficiency: Issues such as a damaged thermostat, a faulty electric fan, or low coolant levels in the cooling system can prevent the coolant in the radiator from cooling down, leading to a rise in water temperature. When the boiling point of water is reached, a large number of bubbles form, occupying part of the radiator's surface area. This results in severe coolant depletion around the cylinder walls, even if there is still coolant in the radiator. Without sufficient coolant around the cylinder walls to dissipate heat, heat exchange efficiency is significantly reduced, making it impossible to transfer heat from the cylinders to the radiator. High-Load Driving: When the temperature inside the cylinders rises rapidly, continued high-load driving without timely heat dissipation can weaken components such as pistons, piston rings, and connecting rods, potentially causing deformation. These parts may then fail to withstand normal loads, and the normal gaps between components can be disrupted, preventing the formation of proper oil films. In mild cases, this can lead to engine cylinder or bearing damage; in severe cases, the entire engine may be damaged or even rendered unusable.
