What is the normal coolant temperature for an engine?
1 Answers
Engine coolant should normally maintain a temperature around 90℃. Both excessively high and low temperatures can cause damage to the vehicle. Lower temperatures indicate stronger cooling performance, but it's important to understand that coolant isn't better when colder. Excessively low temperatures mean greater heat loss from combustion through cooling, and lower operating temperatures result in higher fluid viscosity. Increased viscosity leads to greater resistance in moving parts, reducing power output. Here is relevant information: 1. The primary function of engine coolant is to protect the engine and ensure its proper operation. It circulates within the engine radiator, providing anti-freeze, anti-boil, anti-rust, and anti-corrosion effects. Most coolants are red or green in color to help identify leaks or distinguish them from other engine fluids, preventing confusion. 2. Engine coolant should be replaced based on mileage or time intervals, as it's difficult to visually determine its degradation. If the coolant remains unchanged but its anti-corrosion properties deteriorate, components like the radiator, pipes, and hoses may be damaged. 3. When replacing coolant, measure its freezing point, prevent leaks, and avoid hot coolant from spraying and causing injury. Ensure complete drainage of the original coolant (from both the radiator and engine block), add the correct amount, and avoid leaving any residual leakage on vehicle components. After completing the procedure, check for any leaks.
