What are the reasons for Volkswagen Tiguan burning coolant?
2 Answers
There are several reasons why Volkswagen Tiguan burns coolant: Lack of water: Due to water shortage, the cooling efficiency is low, resulting in the coolant being burned dry. Poor heat dissipation: Due to poor heat dissipation or blockage of the cooling fan or radiator, the coolant is burned dry. Gas leakage: Due to engine gas leakage, the coolant is burned dry, and each part needs to be checked one by one. Coolant, the full name should be antifreeze coolant, meaning coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and expanding the radiator or freezing the engine cylinder block during cold seasons when the car is parked. In normal car maintenance, the engine antifreeze should be replaced every year.
I recently encountered the issue of my Volkswagen Tiguan burning coolant, and it took me quite a while to figure it out. The main reason was a failed cylinder head gasket in the engine, which allowed coolant to seep into the combustion chamber and burn along with the fuel, causing the fluid level to drop rapidly and producing white smoke. Additionally, aging seals in the water pump or radiator can lead to minor leaks, and when the coolant temperature and pressure rise while driving, more coolant can burn off. If the thermostat gets stuck, poor coolant circulation can cause the engine to overheat, accelerating consumption. When I check under the car, I often see wet traces, which are telltale signs. I suggest not delaying and taking it to a professional shop to locate the leak points promptly; otherwise, the engine could be ruined, and repairs can be quite costly. Regular maintenance and checks of the cooling system can prevent major issues, especially for common models like the Volkswagen Tiguan.
