What are the reasons for high water temperature in Volkswagen Tiguan?
2 Answers
Here are the reasons for high water temperature in Volkswagen Tiguan: 1. Insufficient coolant: It is necessary to determine the cause of insufficient coolant, which may be due to not adding coolant for too long or some component failure. If it is because of not adding coolant for too long, simply adding coolant will suffice. 2. Cooling fan failure: It could be due to a broken fan belt or a slipping fan belt. In this case, the cooling fan needs to be replaced. 3. Sensor failure: If there is an issue with the water temperature sensor or temperature sensor, the vehicle cannot detect the temperature, and the cooling fan naturally will not work. The faulty components should be replaced promptly.
Last time I drove my Tiguan back to my hometown, the temperature gauge suddenly shot up. Such high engine temperature is most likely caused by cooling system issues: first, the radiator might be clogged with dirt blocking the cooling fins, with leaves and dust completely covering the air ducts; second, there could be coolant leakage, as old rubber hoses are prone to aging and cracking; third, the electric fan might have failed – I checked by touching the fan bracket after stopping and felt no vibration; another possibility is a stuck thermostat failing to open the circulation channel. Never push through with an overheating engine – I immediately pulled over and turned off the engine to let it cool down, otherwise a blown head gasket would require major repairs. Regular maintenance like flushing the radiator, checking coolant levels, and inspecting hose seals is crucial.
