A water pump basically sends coolant through the hoses looped around the engine block to absorb the excess heat. Since it plays a vital role to keep your engine working, it's obviously imperative that you equip your car with a water pump that meets its requirements. Here are some of the things that you should keep in mind when buying a new water pump:
Different types for different needs
When it comes to choosing a water pump for your car, there's really no definite standard that can tell you if a particular type is better than the other one. You have to consider your car's needs and the driving conditions that it usually goes through. Check out the following types of water pumps:
- Mechanical: A mechanical water pump is the most common type that's present in vehicles nowadays. Since it's widely used, you don't have to worry about its availability. It's also more powerful than its electrical counterpart, which means that it delivers a greater amount of coolant through the engine block at a faster rate. On the downside, a mechanical water pump greatly decreases your car's horsepower and fuel economy. If you're willing to overlook this flaw, then this type is a great choice if you're looking for a durable and powerful water pump that costs less to install.
- Electric: Unlike the mechanical ones, an electric water pump doesn't affect your car's engine performance and fuel efficiency. This type is actually a perfect if you're on the lookout for a water pump that can increase the fuel economy of your car while successfully fulfilling you car's cooling requirements at any temperature range. You should keep in mind, though, that an electric water pump provides a lower coolant flow rate than the mechanical ones.
Choose one according to your budget
Aside from taking your driving needs into consideration, another factor that you should think about before buying a water pump is the amount of money that you're willing to spend. An aftermarket water pump is recommended if you're looking for a budget-friendly solution, especially if you have no qualms about its quality and compatibility. However, if you're fishing for a water pump that's proven to have good quality—and the higher price tag and limited options are no big deal to you—then you should just opt for an OEM instead.
