It’s not uncommon to think about engine, transmission, and other high-tech components while discussing automotive troubles. The water pump, for example, is often overlooked in favor of more well-known components, such as the radiator.
It regulates the temperature of the engine’s numerous components. Overheating or freezing are possible consequences without it. The gasket, the cylinder heads, and the pistons are some of the most expensive parts to repair.

Drivers frequently approached me for advice.
No heat can be caused by a faulty water pump.
When a section of the engine is not working, does that mean that there would be no heat generated by the engine itself?
What Causes Water Pumps To Fail?
Age can be a factor in the failure of a water pump. Experts consider that a water pump has earned the right to retire after delivering more than 1.65 million liters of water.
However, there have been instances where water pumps have failed before they had been predicted to. We’ll focus on the most frequent ones, although there are many others.
1. A Worn Out Seal
There is a chance that the water pump will leak coolant during its lifetime. The water pump housing has a seal around it to keep water from leaking, however it sometimes fails to do so. The seal also serves to keep out outside air, which might potentially damage the coolant.
The seal is leaking for a variety of reasons.
the car is left unattended for an extended period of time with a corrosive coolant, improper installation, or both.
However, the air that leaks in is far more dangerous than losing coolant. Damage to the pump can occur if oxygen is allowed to enter the system.
The engine will overheat or malfunction if air pockets fill the engine blocks.

When you take your car in for maintenance, make sure the mechanic checks the water pump seal to keep your engine safe.
2. Defective Drive Pulley
The water pump’s drive pulley is a component. Weakness in the system indicates that more bad things are to come. Pulley bearings wear out when this portion is loose. This will lead to the failure of the water pump.
The water pump may not be immediately affected by the vibration all of the time, though. It can cause the impeller to become unbalanced, which can have an effect on the water pump, as well.
When replacing the water pump, don’t forget to change the drive pulley as well. Water pumps and driving pulleys are no longer separate components, making things easier.
3. Broken Or Cracked Belt
Water pump pulley belt inspections are extremely unusual. Cracks, breaks, and general wear and tear should be looked for.
It’s crucial to keep an eye on the tightness, as it can easily become loosened. The belt should be just right—not too tight, but also not too loose.
No matter which of the following is true of the water pump, the system will be affected in exactly the same way:
A belt that is too tight will need to be replaced, whereas one that is too loose can be tightened. In the long run, an overtightened belt will lead to the failure of the casting.
4. Corrosion Effect
It’s difficult for mechanics to convey the magnitude of the impact corrosion has on water pumps to automobile owners. Due to corrosion, many water pumps have been deemed unusable.
When a coolant containing tap water is used to replace the original, corrosion results. Only distilled water can be used. Poor cooling system maintenance is another factor that contributes to corrosion.
Except for when it has already claimed victims, corrosion can go undetected for an extended period of time. Corrosion is often only discovered when the impellers begin to fail. The water pump will leak if the damage is substantial.
If you’re using distilled water in your cooling system, be sure that you’re checking the coolant level frequently.
Does The Water Pump Control Heat?

The water pump may not be as critical as the engine, but it does play a role in regulating the engine’s temperature. In order to keep engine parts at the proper temperature, it pushes coolant around them.
How Do I Know If My Thermostat Or Water Pump Is Bad?
If you’re aware of the warning indications of a failing water pump, you’ll be able to catch the issue early on. In some cases, the harm caused by subpar water pumps cannot be repaired.
A leak.
A leaking coolant is almost often the result of a faulty water pump. After leaving your car in the garage or parking lot for a while, you’ll notice it on the floor. A worn seal is to blame.
Look for a blue, pink, or green liquid on the ground if you fear your water pump is malfunctioning.
Rust
It is important to keep the water pump clean and rust-free. It accumulates, weakens, and eventually destroys the pump. Use of subpar coolants or air entering the pump can cause rust, so make sure there are no leaks and the pressure cap is effective enough to prevent this.
Any evidence of corrosion surrounding the water pump can reveal the presence of rust.
Noise
As soon as the water pump belt gets loose, the engine’s front produces weird and high-pitched sounds. It is imperative that you take your vehicle to the technician as soon as you notice any of these noises.
Over Heating
The water pump is responsible for regulating the temperature of the water in the system. It’s possible that the water pump is faulty if the automobile overheats.
How Do I Check If My Water Pump Is Working Without Removing It?
- Place a cardboard piece under the car water pump and observe for a leaked coolant after some time (overnight).
- Listen for odd sounds coming from the engine area.
- The temperature warning is a sign of a faulty water pump.
- If the coolant light is on, that’s a bad sign.
What Does A Bad Water Pump Sound Like?
Whining, squeaking, and grinding are common characteristics of the noises made by these devices. Consider the fact that not all faulty water pumps create noises.
Can A Water Pump Go Bad Without Leaking?
A leaking water pump is only one of the many warning signs of a broken pump. Other causes of pump failure include rusting from air entering through a faulty pressure cap. Don’t only look for leaks when you’re inspecting.
How Long Can You Drive With A Bad Water Pump?
You should keep the distance to a minimum, according to the advice given. There is a considerable risk of overheating because the car’s cooling system isn’t working properly. This can seriously harm the engine.
Bottom Line
Let’s not forget about the water pump while we’re taking care of the engine and other critical components. It has a critical function to play in keeping our automobiles on the road, and ignoring it may be costly.
In the event of an emergency, you should always keep an eye on your dashboard temperature.
