Every combustion engine vehicle has a cooling system that keeps the coolant flowing into the engine from the car radiator in order to keep your car engine cool. The water pump happens to be one of the most important parts of a car cooling system.
A nonfunctional water pump can result in overheating, thereby causing more damage to your car engine and sometimes resulting in fire outbreaks from your engine.
It is very important and mandatory to replace your car’s water pump as soon as you notice it is malfunctioning. This prevents your car from further damage.
To give you an idea of the necessities of water pump replacement, we will review the average cost of replacing a car water pump, the pros and cons associated with water pump replacement, and a DIY replacement process.
Type of Automobile Water Pump
Electric Water Pumps
This type of water pump helps to effectively reduce engine heat, it is mostly integrated into a modern engine. Electric pumps allow cooling according to the system’s needs.
It also reduces engine power required, and this, in turn, minimizes pollutant emission, consumption of fuel and friction losses.
Mechanical water pumps
In this type of pump, the coolant gets heat from the cylinder head and engine block and then releases it into the atmosphere through the radiator. Mechanic pumps are common in vehicles, and they are very effective.
Auxiliary water pumps
Auxiliary water pumps support the main water pump. Depending on the car’s cooling system, some cars can have more than one auxiliary pump.
Variable water pump
The variable water pump acts on the cooling system when needed. It increases the performance of your engine causing fuel to be consumed at a lower rate, resulting in a reduction of pollutants in the environment.
Water Pump Car Replacement Cost
The cost of a water pump replacement depends on factors like the make and model of your vehicle, your mechanics’ pay rate per hour in your locality, and if other parts are required to be replaced alongside the water pump.
In most cases when a car has a broken or faulty water pump you might have to also replace the water lines, the timing belt, etc.
Although a water pump cost around $150 -to $1500 to replace. As earlier stated, the cost of replacing a water pump depends on the make and model of your car and the cost of labor.

Two Water Pump Replacement Options to Consider
Rebuilt/Remanufactured Water Pump
Getting a rebuilt/remanufactured water pump can help save more money than getting a new one. But it is not always a good option as a rebuilt water pump cannot be compared to getting a new one.
Remanufacturing a water pump is aimed at reducing cost, and in that regard, sub-standard materials are used.
Most rebuilt water pump comes with a nominal warranty if any at all. They might sometimes have oversized bearings meant to make up for wear on the shaft and housing resulting in the risk of failure.
New Water Pumps
Replacing a broken or faulty water pump of your car with an OEM quality part can be slightly expensive in cost.
Most manufacturers tend to sell brand-new water pumps at a competitive rate. It comes with a warranty which is a much better deal, and the recurring problem is greatly reduced compared to getting a rebuilt water pump as it tends to cause more problems in no time.
Advantages of Water Pump Replacement
Replacing a broken or faulty water pump helps the car reduce engine noise. Older water pumps have a bearing with some tear and wear causes the water pump to make a whining and grinding noise while your car is in motion.
Older water pumps are likely to have a worn bearing and this leads to an increase in friction, resulting in a loss of engine efficiency. Replacing a worn water pump lead to an increase in engine efficiency and it also helps to save fuel.
Procedure for Water Pump Replacement
Before replacing your cars water pump, be sure to park your car in a dry level place, and park the wheel straight to allow the engine to cool down. Remove and keep the negative post from the battery in a place where it won’t come in contact with metal.
Drain the coolant using an oil drain pan. After it has completely drained, cover the pump.
Apply gasket sealant to the water pump after you’ve installed the gasket.
Use the right screwdriver to unscrew the clamp connecting the hoses to the water pump. Pour any liquid remaining into the drain pan.
Take out the water pump retainer nuts. It’s advisable you get a good removal tool.
Clean and scrap if the gasket seal is stuck in its position.
Ensure that the pump is properly fastened before replacement. Use a gasket sealer to prevent it from leaking.
Make sure the hoses and clamps are secured properly to avoid leakage.
Using a belt tension gauge, adjust the belt tension to its appropriate length.
Finally, before you start your car engine, ensure that the coolant system is properly refilled. Wait and observe for leakages before you drive.
It is an important component of the cooling system that keeps the coolant circulating, it also plays a crucial role in ensuring the engine operates at its appropriate temperature. So yes, replacing an old and malfunctioning water pump is worth it.
It is safe to say getting a new pump to replace an old worn bearing can lead to a small increase in the regulation of the cars engine and help to save fuel and reduce engine noise.
