What Happens When the Cooling Fan Fails?
1 Answers
The blower resistor is primarily used to control the blower speed. If the blower resistor is damaged, the blower will operate at the same speed across all gear settings. Once the blower resistor fails, the air volume control knob loses its speed adjustment function. Below are the symptoms of a damaged water pump: 1. Reduced cooling circulation capacity: A faulty water pump can weaken or even halt the cooling circulation, leading to coolant boiling. 2. Coolant leakage near the engine's water pump: Coolant may leave traces of its color around the water pump's ventilation holes, resulting in symptoms like high water temperature due to coolant shortage. 3. Abnormal noise from the water pump during engine operation: Unusual noises from the water pump may be caused by internal debris or bearing wear.
