How to Determine a Lack of Coolant?
1 Answers
Methods to determine a lack of coolant include observing the coolant warning light on the dashboard; checking the coolant reservoir; and inspecting the water level markings on the coolant overflow tank. Observe the coolant warning light on the dashboard. If it lights up, it is likely due to a lack of coolant, though it could also be caused by excessively high engine temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add coolant. Inspect the water level markings on the coolant overflow tank. The coolant level should normally be between the maximum and minimum marks. To determine if coolant is lacking, check the markings—if the coolant is below the minimum level, it indicates a shortage. Coolant replacement intervals: For vehicles that operate for extended periods, such as taxis, high-quality coolant should generally be replaced annually. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foaming, which reduces the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolant can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the coolant, replace it promptly and clean the system.
