You may need to have your vehicle's water pump replaced if you notice a coolant leak that seems to be coming from behind the timing belt cover on the engine, or you notice that your temperature gauge is beginning to fluctuate.
What it does
This impeller pump, which is usually located under the timing belt cover on the side of the engine, is responsible for circulating coolant through the engine that absorbs the heat produced by combustion. The pump is driven by the engine's drive belt.
If this belt becomes loose or worn, or breaks, the pump stops working and the engine will soon follow, unless immediate action is taken. Water pumps usually last about 90,000 to 120,000 miles, but may fail sooner.
TIP: If a low-pitched grinding noise is coming from under the hood, it may be an indication that the water pump bearing is going bad.
