Can Antifreeze Cause High Engine Temperature?
1 Answers
If antifreeze is added or replaced improperly, it can lead to premature blockage of the engine water passages and radiator, resulting in high engine temperature. Antifreeze should be replaced every two years, and only original equipment manufacturer (OEM) antifreeze should be used during replacement or addition. If the concentration is too high, it can result in poor heat dissipation and engine overheating. Different types of antifreeze should not be mixed, as this can cause chemical reactions, produce sediment or bubbles, and reduce effectiveness. When replacing antifreeze, start the engine first, then stop the engine to drain the cleaning solution. Fill the cooling system with clean water, let it idle for 10 minutes, then drain. Repeat this process several times until clean water flows out of the water passages, and then add the new, properly mixed antifreeze and water.
