What Causes Coolant to Boil Over?
1 Answers
It may be caused by the radiator stopping operation, leading to excessively high water temperature. Coolant boiling over actually refers to the situation where, during driving, the engine's high temperature causes the coolant temperature to rise, reaching a boiling state. When the boiling coolant overflows and comes into contact with hot metal parts, white smoke appears. Coolant boiling over can be caused by the radiator stopping operation, resulting in excessively high water temperature; the coolant not circulating due to the thermostat not opening; or the water pump failing to function properly, causing blockage in the water circulation pipeline and leading to boiling over. Below is an introduction to automotive coolant: 1. Introduction to Automotive Coolant: Automotive coolant, fully known as automotive antifreeze coolant, is a coolant with antifreeze properties. To ensure that cars can continue to operate during winter's low temperatures, substances that lower the freezing point of water are added to the engine coolant as antifreeze agents, preventing the cooling system from freezing in cold weather. 2. Functions of Coolant: Coolant can prevent the cooling liquid from freezing and expanding when the car is parked in cold seasons, which could otherwise crack the radiator and damage the engine cylinder block.
