What does it mean when the vehicle prompts to check the coolant?
2 Answers
The vehicle prompting to check the coolant indicates a low coolant level, which can cause engine overheating. Other possible causes include poor grounding of the coolant pump, coolant pump failure, or excessive dirt buildup in the radiator. Related to coolant level: In this situation, it is necessary to check whether the coolant level is normal, whether the radiator fan is operating properly, whether the radiator is severely clogged with dirt, and whether there is corrosion or poor contact in the coolant pump grounding. Definition of coolant: Coolant, also known as antifreeze, is a liquid composed of antifreeze additives, additives that prevent metal corrosion, and water. It needs to have properties such as antifreeze capability, corrosion resistance, thermal conductivity, and resistance to deterioration.
Seeing the vehicle prompt to check the coolant indicates there might be an issue with the cooling system. The coolant circulates within the engine to dissipate heat and maintain the engine's optimal operating temperature. The most common cause is low coolant level, which could be due to a leak in the radiator or not topping up the fluid for a long time. It could also be a false alarm from a faulty sensor, such as misjudgment due to aging. Additionally, a malfunctioning water pump can hinder fluid circulation, potentially leading to overheating. I've encountered similar issues before—promptly stopping to check the coolant level and adding the appropriate coolant as a temporary fix can prevent engine damage. Regularly replacing the coolant is crucial, typically every two years, to avoid corrosion buildup. Never ignore this warning, as high temperatures can easily cause engine seizure, leading to costly repairs. It’s best to visit a shop for a thorough inspection to ensure peace of mind.
