How to Determine If a Car Has Insufficient Coolant?
1 Answers
Methods to determine if a car has insufficient coolant are: 1. Start the vehicle and let the system perform a self-check. Check the vehicle's dashboard, where there will be a fluid level indicator; 2. Pull the handle inside the driver's seat to open the hood, then inspect the coolant reservoir, which has markings for high and low levels. Coolant refers to a liquid containing special additives, primarily used in liquid-cooled engine cooling systems. Precautions for its use include: 1. Do not mix different types of antifreeze; 2. Do not open the radiator cap or drain valve immediately after driving the car; 3. When replacing the coolant, ensure all old antifreeze is completely removed and the radiator is thoroughly cleaned.
