6 Symptoms of a Bad Water Pump (Function & Location)

A coolant pump keeps your car’s radiator and cooling system well-cooled by pumping coolant through it. You can tell if your water pump is bad by checking the temperature of your engine’s coolant. If it is low, it is time to get your water pump replaced.

You need to keep an eye on this temperature, as otherwise, the engine could overheat, which might damage it.Therefore it is vital to change your water pump before it breaks totally, but how do you know if your water pump is about to go bad? Here are the most important signs to look for:

6 Bad Water Pump Symptoms

The most common symptoms of a bad water pump are coolant leaks under your car and an overheated engine.

Leaking of Coolant

Leaking of coolant is one of the most common symptoms of a water pump. It usually happens when the water pump loses power. A damaged water pump may fail to pump enough coolant into the engine to keep it cool enough. If you notice coolant leaking from your vehicle, stop immediately and call a mechanic. In the meantime, turn off the engine and park the vehicle. Do not drive it.

Squealing Noise

If you hear a loud, screeching noise while driving, or the car seems to hesitate before starting, this could mean that there is something wrong with the water pump. If the water pump fails, the pressure that pushes the water to the radiator could cause the engine to seize. If you are experiencing a squealing noise in your vehicle, you should stop immediately and call a mechanic. Park your vehicle safely and wait until the car has been stopped. Do not attempt to drive it. Severely Overheated Engine

The next sign of a bad water pump is an overheated engine. The most common sign of this problem is an overheated engine block. This is when a leak occurs in the engine and the coolant in the engine begins to boil.

Water Pump’s Axle lose

This is the only way the water pump works. It turns and pumps coolant. A loose belt might make the water pump malfunction. Check the axle, then replace it. This water pump is damaged and needs to be replaced. If the water pump’s axle isn’t loose, then the serpentine or timing belt must be removed. If you feel a bit of play in the axle, replace it immediately.

Overheating Engine

There are a lot of reasons why overheating engine problems occur. One reason is that the radiator hose may burst. Another reason is that the radiator cap may be cracked. The coolant level may be low. When the water pump malfunctions, it means that the coolant isn’t pumping and cooling the engine. In a hot environment, this can lead to overheating. There are many symptoms of a overheating engine, and most of them are fairly simple to fix.

First, check the battery. If the battery is not charged, the car won’t start. When you check the battery, remove the spark plug and remove the positive terminal. Then charge the battery for 30 minutes. Next, check the engine oil. You may smell an oil leak. If the engine oil is leaking out, then change the engine oil. Next, check the radiator. The radiator may be full. It might be leaking. The hoses might also be cracked. Check all the hoses.

White Smoke From The Radiator

A leaky water pump is a common reason that your radiator smokes. It’s easy to solve a radiator problem when the water pump is in good working order. It’s better to stay safe and stop driving, wait for the engine to cool down, and then try to reach a repair shop to get help.

What is a water pump?

The water pump is a mechanical part that helps circulate water throughout the engine. It moves water from the radiator into the cylinders, and then back to the radiator. Without a water pump, it’s impossible to have cooling water. A water pump is powered by the engine and it keeps the engine lubricated. It moves all the coolant, which is a mixture of antifreeze and water. It also turns on the fuel injectors.

When a car doesn’t have enough coolant, it can overheat. When the engine gets hot, it produces lots of steam. When the engine overheats, it can melt the hoses that carry the coolant around. When this happens, you may see white smoke coming out of the radiator. A cracked radiator can also cause the engine to overheat.

Water Pump Location

A water pump is always located next to the serpentine belt, timing belt, or timing chain since it is powered by one of them. This means that it is also installed at the front of the engine.


Can you drive a car with a bad water pump?

You should never drive your car at all if the water pump is bad. Your car’s water pump should be changed when it starts making unusual noises. A bad water pump can cause your engine to overheat, which can cause it to overheat.

Will a new water pump improve performance?

It’s not an essential part of any vehicle, but it will improve your engine’s performance by keeping it cooler and improving cooling performance. However, it depends on the cooling performance of the old water pump. If an old pump was working properly, it is unlikely that replacing it with a new pump will improve performance.

How long can I drive with a bad water pump?

Water pump failure will be the cause of death for your car if the water pump is bad. You shouldn’t drive your car at all if your water pump is bad. An overheated engine may lead to expensive repair costs. It may also result in damage to your engine.
