The two most likely causes of engine overheating at Renault Sandero is a cooling fluid leak or cooling fan failure.
If the WF level is all in order and the fan is working directly, it may not be possible for the fan to turn on. Also, the reason may be that the radiator is closed-especially if it has been used to repair the radiator. A defective thermostat may also cause overheating. In addition, the engine may be overheated by the use of low octane gasoline or a defective cork.
