What to do if you notice a leak in your coolant?
If you notice there is a leak of coolant (which will appear to be green or sometimes red in color) under the center of your car, truck or SUV, contact a professional mechanic to inspect this problem. More often than not, it's a leak from the water pump that can be repaired before it gets worse. 2.
Why does my car need a water pump?
In order to run cool on those hot summer days, your engine needs to have a consistent flow of coolant supplied from the radiator throughout the engine. The water pump is the primary component responsible for maintaining this flow. When it works properly, your car will maintain a consistent operating temperature, run smoothly, and take you anywhere you need to travel. When the water pump fails or is beginning to wear out, it can lead to complete engine failure.
How to tell if your engine is overheating?
Finally, if you notice steam is coming from the front of your motor as you drive or come to a stop, it is an instant sign of an overheated engine. As discussed above, an engine will maintain a consistent temperature when the water pump works correctly and circulates water to a functioning radiator. If you notice steam coming from the front of your motor, you should pull over to a safe area and contact a mechanic as soon as possible. It's never a good idea to drive an overheating engine, so if you have to contact a tow truck to get the car home, this could save you significant money in the short and long term – it's going to be less expensive than replacing the engine entirely.
Why does my water pump make a loud noise?
From time to time you might hear a high pitched sound that comes from the front of the motor. This is typically caused by a loose belt that creates a harmonic buzzing or whining sound as it circulates. The loose belt is commonly caused by a pulley that has become loose or that the bearings that operate the water pump assembly are wearing out. Once the bearings fail inside the water pump, it means the unit cannot be repaired and will need to be replaced entirely.
What does it mean when a water pump fails?
Once the bearings fail inside the water pump, it means the unit cannot be repaired and will need to be replaced entirely.

How does a water pump work?
The water pump moves the coolant through the coolant passages that are located in the engine. The coolant helps keep the engine temperature low. The flow of coolant is held back by the thermostat until the coolant reaches the desired temperature, when the thermostat opens up and allows the coolant to flow through the radiator hose into the radiator.
What to do if you think your coolant reservoir is leaking?

What is the job of a water pump?
The water pump is a part of your vehicle with an important role in the engine's cooling system. The job of the water pump is to cool down the engine with coolant, which in turn assists in making sure the engine does not overheat. Engine overheating is a very dangerous thing for your car and could lead to eventual engine failure.
What happens if a water pump isn't replaced?
Note that if a leak isn’t taken care of, your engine is almost guaranteed to overheat if the water pump isn’t replaced immediately.
What does it mean when you lose coolant?
There’s a leak somewhere in the cooling system other than the water pump. If you’re losing coolant for a reason not mentioned above, you likely have a leak in your radiator or one of the hoses in your system.
Why is coolant important?
For your car, coolant is just as important to keep topped off as any other fluid. It protects your engine from high heat as well as freezing temperatures. The water pump cycles coolant from the radiator throughout the engine, absorbing the heat and wicking it away into the atmosphere. When water pumps go bad, it causes your engine to overheatand that leads to all sorts of trouble.
What happens if a bearing seal is worn?
A worn bearing seal. Leaking coolant will slowly dissolve the protective layer surrounding the seal, causing it to overheat and eventually collapse. A collapsed bearing WILL directly effect your engine.
What is a defective impeller?
The impeller’s job is to distribute coolant throughout the system, and if it were to detach, overheating would occur.
Why does my temperature gauge go up?
Normally, your vehicle’s temperature gauge should remain steady, settling somewhere between cold and hot. If coolant isn’t getting pumped through the system , the impeller has most likely malfunctioned. This causes the temperature gauge needle to go up.
What does it mean when you see a puddle of fluid under your engine?
If you discover a puddle of fluid underneath your engine, that could be a sign of a bad water pump that’s leaking coolant. This happens when:
Why do water pumps circulate coolant?
To prevent it from overheating, the water pump circulates coolant throughout the engine and cooling system to remove heat from critical engine parts. This helps the engine, engine oil, and transmission fluid operate at optimal temperatures.
How to test coolant?
Testing your coolant can be done using a handheld antifreeze tester. This handy tool allows you to measure the freezing point of your coolant and adjust the water to coolant ratio accordingly. We recommend using distilled water to dilute the coolant if the ratio is too high. To increase the coolant ratio, use a full strength coolant like PEAK Long-Life Full Strength.
What causes water pump failure?
Water pump failure can stem from the condition and amount of coolant in your vehicle’s cooling system. Your vehicle’s engine is working extremely hard, and in turn, generating lots of heat. To prevent it from overheating, the water pump circulates coolant throughout the engine and cooling system to remove heat from critical engine parts. This helps the engine, engine oil, and transmission fluid operate at optimal temperatures.
What happens if your water pump temperature rises?
If your engine temperature rises, things can get troublesome pretty quickly. At just 18-degrees above its normal temperature, the important inhibitors in the coolant that protect the water pump from cavitation, rust, scale, and sludge become less effective. As these degrade, failure of your water pump can occur.
Can you check coolant levels when it's hot?
Have you checked your coolant levels lately? Each time you open the hood is an opportunity to monitor coolant levels and get a reading on your vehicle’s health. Remember, never check coolant levels when the engine is hot. Wait until the engine has cooled and the system has depressurized before opening the radiator cap or pressurized overflow tank. If the level is low, you can refill quickly using widely compatible premixed coolant like PEAK Long-Life 50/50.

Why does my water pump work?
Its main job is to move coolant from your radiator throughout your engine to prevent overheating. When it’s working, your engine runs at the right temperature. If it stops working, your car can overheat, potentially resulting in costly repairs.
Can a failing pump cause an engine to overheat?
If you notice that your engine is running hotter than normal, even if no warning light is illuminating on the dashboard, then it’s a good idea to have the system checked. Don’t assume you have to see leaking coolant somewhere for there to be an issue. The problem could be inside the pump itself, where worn impeller blades are no longer doing their job of keeping coolant moving.
