5 Car Water Pump Failure Symptoms
What is a water pump? A car’s water pump’s job is to pump coolant to the engine and radiator so that the engine can maintain a safe and stable temperature while it’s running. If the water pump fails, there won’t be enough coolant flowing through the engine, which can cause the engine to overheat and overheat.
This can lead to failure of the engine’s gaskets, cylinder head, and other components. If left unrepaired, the engine can become so damaged that it will require an overhaul. A car’s water pump has a lifespan of 100,000-150,000 km and is usually replaced when the timing belt is replaced.
Paying attention to the condition of your water pump can help ensure it is functioning properly and prevent damage to your engine. To help you out, here are five signs of a failing water pump:
1) Coolant leaks
Your car’s water pump has a seal that properly seals the pump and ensures a consistent flow of coolant. However, over time the seals can dry out, crack, break or wear out. When this happens, coolant can leak from under the water pump, which is usually located in the front center of the car.
Keep in mind that coolant can be different colors such as green, yellow, and blue. Therefore, knowing the color of your coolant will help you identify a leak if there is one.
2) Sediment or corrosion in the water pump and engine bay
One of the symptoms of a failing water pump is the buildup of sediment on the water pump and the components around it. If a small leak in the water pump goes unnoticed and the spilled coolant dries on surfaces after a long time, deposits can form. If left for a long time, this can corrode the water pump and surrounding surfaces.
Corrosion on or around the radiator is an indication of a problem with the water pump or cooling system. If you notice deposits or corrosion, it could mean that the engine coolant is not compatible or contaminated, mineral deposits in the cooling system, or air is leaking from a faulty radiator pressure cap.
To discover these problems before it’s too late, it’s a good idea to check the engine compartment from time to time to make sure it’s free of deposits and corrosion.
3) Loose timing belt, squealing noise
The water pump in most cars is driven by a timing belt. If the timing belt becomes loose, you may hear a squealing noise from the water pump or belt when starting the engine.
A loose timing belt can be caused by worn pulleys, axles, or bearings in the water pump, which usually requires water pump replacement. In addition, a loose timing belt can turn on the check engine light and cause a rough ride. If you notice any of these signs, you should have your car inspected by a mechanic immediately.
4) Engine Overheating
The main function of a car’s water pump is to cool the engine. If it fails, it can’t pump coolant effectively to the cooling system, which can cause the engine to overheat. Driving with an overheated engine can affect the performance of your car and cause costly engine damage.
5) White smoke coming from the radiator
Another symptom of a faulty water pump is steam or white smoke coming from the radiator. This occurs when the engine overheats and the coolant turns into steam. If steam comes out of the engine while driving, immediately stop the car in a safe place, let the engine cool, and then call a mechanic. If necessary, use a tow truck to tow the car to the nearest repair shop.
