If you're craving for a cool breeze once you enter your car, you just simply turn on your AC to full blast. But what if your engine's the one that needs cooling? Then it is the auxiliary water pump's turn to keep it comfortable. The auxiliary water pump, a part of your engine's cooling system, is responsible for the consistent flow of coolant into your car's heater core. Its importance to your engine's everyday function is simple and straightforward, but choosing the perfect one for your car isn't. Here are a few dos and don'ts when it comes to shopping for a new auxiliary water pump:
- Choose an auxiliary water pump that is made of sturdy material, such as high-grade steel. Since the water pump is at the part of the engine where it is most exposed to high temperature, it must be able to withstand the nature of its environment. Also make sure that it is corrosion and rust resistant to prevent premature wear of your auxiliary water pump.
- Inspect your preferred auxiliary water pump before purchasing it. Unlike other parts of your engine cooling system, it is more complex because of its electric component. Make sure that aside from looking through the seals, bearings, and the pump's other hardware, you should also check its internal electric parts.
- Invest in a name brand auxiliary pump rather than purchasing cheap aftermarket products. This will not only ensure the pump's consistent quality, but it can also guarantee a perfect fit. Since no modifications are needed to fit an OE auxiliary water pump to your system, you can also save time and money on installation.
- Don't replace your auxiliary water pump with a second-hand part. Although this is a cheaper option, it is also the most unreliable one. Second-hand or refurbished auto parts can be a dangerous addition to your system. It carries an unknown amount of mileage and you basically don't know what it has gone through before reaching your car. Busted bearings may have been welded together or other parts may be replaced with substandard ones. These minor kinks in refurbished pump could result in unnecessary damage to both your radiator and engine.
- Don't be stingy about replacing an auxiliary water pump. Opt to get an extended warranty. Purchasing an extended warranty plan has many benefits that can add more value to your water pump. There are a lot of suppliers that offer a reasonable extended warranty plan. Be sure to read through the different limitations and conditions of the plan before you decide which one's best for you. Scrutinize it thoroughly to ensure that the extra insurance that you're paying for will not go to waste.
