Water Pump Replacement Inconveniences Are Easily Avoided

Even if you’ve never gone through water pump replacement yourself, you probably know someone who’s suffered a failed water pump. Your car water pump is a vital component of the cooling system for the engine. This is a fairly precise system in which the water pump pushes coolant through specific access points in the engine. The coolant is restrained by the thermostat until it achieves the desired temperature at which point it then passes to your radiator. A full system is in place to deal with the superfluous heat produced in the process. However, the water pump is still in action, sending the coolant back through the engine in a constant cycle. As you can imagine, the disruption of this process can be bad news for your car. Luckily, there are several symptoms to help keep you aware of whether water pump replacement is necessary.

Leakage and Seepage

This coolant leak indicates the need for replacement of a car’s water pump.

A failing water pump can often be a messy affair. It’s a good idea to get acquainted with your water pump’s weep hole as the presence of any seepage or leakage in this area is a strong indicator of water pump problems. New water pumps are initially meant to leak slightly as the seal takes some time to set. But if your water pump has seen some use, coolant leakage at the weep hole is trouble. In addition, any signs of coolant dampening the mounting areas or the surface of the water pump and surrounding components is a strong indicator that water pump replacement is necessary. If you find any signs of leakage or coolant contamination, it’s a good idea to inspect your car’s coolant reservoir for issues.

Visual Signs of Need for Water Pump Replacement

While you’re checking for leaks, you can also visually inspect the water pump and pulleys. If contaminated coolant has built up, it could be impeding the flow of the water pump. Often you can clearly see the residue built up. You may also see easily distinguishable rust build up. In some cases, you may notice deterioration of the pulleys as a result of a process called cavitation in which vapor bubbles violently burst, resulting in eroded wounds across the related components.

Temperature Testing

Some simple temperature tests can help determine whether your water pump is experiencing issues.

You can do a series of temperature tests to give you an indicator of issues that may require water pump replacement. If you blast your heater and are initially greeted with chilled air, it probably means that your coolant isn’t circulating properly. Obviously, this is an indicator of problems with the water pump. A more obvious temperature-related signal is the temperature gauge on your dash. Some cars rely on ever-present gauges while others will illuminate warning lights to inform you that your engine is overheating. In the event that your engine is overheating, cease driving immediately before you do severe damage to the engine and consider having your vehicle towed to a reliable auto body shop for potential water pump replacement.

An overheating engine is the ultimate symptom leading to the replacement of your water pump. Regular tune ups can keep you from having to come to this realization on the side of a freeway on your way home from work. The costs associated with water pump replacement aren’t usually too severe but it can be an inconvenient repair if you’re not prepared for it. As always, it’s best to stay aware of your car’s condition so that maintenance remains easy and worry free.
