The main reasons for the frequent damage to the Geely Emgrand water pump are as follows: 1. Aging of the water pump sealing ring; 2. Over-tightening of the engine combination belt; 3. Long-term failure to replace the antifreeze; 4. The water pump reaching the end of its service life. The following are the symptoms of water pump damage: 1. Coolant "boiling over." Damage to the water pump weakens or even stops the cooling circulation, leading to the coolant "boiling over." 2. Coolant leakage near the water pump area of the engine. Coolant leakage leaves traces of coolant color on the water pump ventilation holes, resulting in symptoms such as elevated water temperature due to insufficient coolant. 3. Abnormal noises from the water pump during engine operation. Abnormal noises from the water pump may be caused by internal foreign objects or bearing wear.
My Emgrand's water pump had an issue before, where the bearing wore out too quickly because I often drove in congested urban areas with fluctuating water temperatures, which accelerated the wear. I also discovered that the coolant used wasn't the one recommended by the manufacturer, which corroded the sealing ring. When replacing the water pump, the mechanic mentioned that this car's design tends to accumulate debris easily, and regularly cleaning the radiator can extend its lifespan. Other car owners have mentioned that loose belts or tensioner failures can also affect the water pump, especially in older cars. It's best to inspect the cooling system annually; spending a few hundred yuan can save thousands in repair costs. Otherwise, if the water pump fails and causes engine overheating, the consequences could be much more severe.
