How often should the water pump of Nissan Tiida be replaced?
2 Answers
Nissan Tiida's water pump only needs to be replaced when it is damaged. Here is an introduction to the water pump: 1. Composition and structure: Automobile engines widely use centrifugal water pumps. Their basic structure consists of components such as the water pump housing, connecting plate or pulley, water pump shaft and bearings or integrated shaft bearings, water pump impeller, and water seal device, making them a major part of the automobile. 2. Symptoms of water pump damage: (1) Damage to the water pump can weaken or even stop the cooling circulation, leading to coolant boiling. (2) Leakage near the water pump area of the engine. Leaking coolant leaves traces of coolant color on the water pump ventilation holes, resulting in symptoms like high water temperature due to insufficient coolant. (3) Abnormal noises from the water pump when the engine is running. These noises may be caused by foreign objects inside the pump or bearing wear.
I've been driving a Tiida for ten years, and there's no fixed time for the water pump issue. Last time I replaced it at 120,000 kilometers, but the mechanic said you should generally pay attention to inspections around 100,000 kilometers. Every time I change the timing belt, I ask the mechanic to check if the water pump bearing is loose or if the seal is leaking. If you hear a squeaking sound from the front of the engine or the temperature gauge keeps hitting the red line, chances are the water pump is failing. My neighbor ended up spending 5,000 yuan to repair the engine because he delayed until the timing belt skipped teeth. Now, even the maintenance manual doesn't mention the water pump replacement cycle, so you just have to stay vigilant. Remember to replace the coolant when changing the water pump, or the new pump won't last.
