What are the symptoms of a faulty truck water pump?
1 Answers
A faulty water pump in a truck can cause the engine to overheat and damage the engine. If the water pump is damaged, the coolant cannot circulate within the engine, which affects the engine's cooling. The water pump provides the power for the coolant circulation, and the coolant has two circulation paths within the engine: one is the major circulation, and the other is the minor circulation. When the engine is just started, the coolant undergoes minor circulation, during which it does not pass through the radiator, helping the engine to warm up quickly. Once the engine reaches its normal operating temperature, the coolant switches to major circulation, passing through the radiator to dissipate heat, thereby maintaining the engine within a reasonable operating temperature range.
