How Many Bars on the Van's Temperature Gauge Are Normal?

[StGrant]

It is normal for a van's temperature gauge to be 2 bars below the maximum. Below are the reasons for temperature gauge malfunctions: 1. Leakage or insufficient coolant: A leak in the cooling system can lead to insufficient antifreeze, causing the antifreeze temperature to rise. If the antifreeze level is found to be low, the first step is to check for leaks. If there are no leaks, promptly add the same type of antifreeze. Do not add tap water or other types of antifreeze to avoid dilution or sedimentation, which may lead to failure or malfunction. 2. Radiator fan failure: A malfunctioning radiator fan can prevent timely dissipation of heat generated by the car engine during medium to high-speed operation, causing the antifreeze temperature to rise and leading to issues like "boiling over." While driving, always monitor the antifreeze temperature. If an abnormality is detected, reduce speed and stop the vehicle, but do not turn off the engine. Check whether the radiator fan or circulation water pump is malfunctioning.
