Anyone who works in a garage will be familiar with car water pumps.
But do you know just how important the component is to a car engine? Read the rest of the article to find out what they’re for, how to ensure they’re upkept and much more.
What is a car water pump?
Water pumps are components located next to a car engine, working to pump antifreeze into a car’s engine block.
The process allows the engine to withstand the high temperatures produced by the combustion that takes place in the cylinders, allowing an engine to keep working effectively.
This component is powered by the electricity produced by the car alternator.
Which components make up a car water pump?
- Impeller;
- Bearing;
- Blades (straight, curved, tangential, or radial).
A water pump operates thanks to the movement of the impeller as it rotates the blades, sending the antifreeze to the engine via a centrifugal force.
Car water pumps are divided into various types of units.
Keep reading to find out the various types of water pumps.
What are the different types of water pumps?
- Belt-drive;
- Direct drive.
What are car water pumps for?
Water pumps work by pumping the engine antifreeze (or coolant) from the radiator to the engine block so as to maintain the engine temperature.
If a water pump is faulty, the antifreeze will be unable to circulate, and the temperature of the engine may well rise to levels that compromise its ability to operate.
It’s worth remembering that a car engine may break down when it reaches high temperatures.
How durable is a water pump?
The useful life of a water pump is around 120 thousand km with the right care. However, you should always make sure to check on your water pump when carrying out any periodic maintenance on your car to ensure it’s always kept in good working order.
3 Maintenance tips for your water pump
- Check your antifreeze or coolant levels
Check the levels of antifreeze or coolant in your car.
- Use the right liquids
Always use the antifreeze or coolant suggested by your vehicle manufacturer in the right quantities.
- Watch for leaks
A water or antifreeze leak can happen in any car. Check for stains under your vehicle by placing a piece of cardboard under the engine.
What are the signs your water pump may be in poor condition?
· Water leaks
If your vehicle is leaking water out of the bottom of the engine, it may be a sign of a leak in the water pump.
· Loose timing belt
If your car’s timing belt is showing signs of wear, you’ll need to replace your vehicle’s water pump.
· Engine making various noises
When your engine is operating more violently, it may be a sign of a failure in your water pump, which cools your engine.
· Rust on your water pump
Every car component must be checked during periodic car inspections, and your water pump is no exception. If it shows any signs of rust, it should be replaced.
· Thermostat or coolant warning lights
If the thermostat or coolant warning light comes on on your dashboard, it may mean your antifreeze is leaking.
If you find yourself in this situation, make sure you take your car to your trusted mechanic to have the water pump and all adjacent components checked.
· Engine overheating
When your engine reaches higher temperatures than normal, this may indicate water pump failure.
How much does a car water pump cost?
Water pump prices start at 30 euros, depending on the model you choose.
KROFtools suggests consulting your trusted mechanic or a manufacturer-approved garage if you’re looking to replace your pump.
