What does the Volkswagen Passat dashboard water temperature gauge light indicate?
1 Answers
The illuminated water temperature gauge on a Volkswagen Passat indicates a fault in the engine's cooling system, which prevents it from effectively cooling the engine. The water temperature gauge is located on the dashboard, with 90 degrees being the normal operating temperature. Both excessively high and low water temperatures can affect the engine's performance. Adding coolant: Insufficient coolant in the cooling system can cause the engine to overheat. It is necessary to stop the vehicle and wait for the engine to cool down before adding coolant. Replacing related components or clearing debris: A water pump or fan belt that is too loose or broken can lead to engine overheating. These components should be replaced at a repair shop. If the radiator guard mesh or radiator core ventilation ducts are clogged with debris, it can result in poor heat dissipation and cause the engine to overheat. Replace the radiator guard or clear the debris.
