Do Subaru water pumps go bad?
Yes, Subaru water pumps can go bad over time. Like any mechanical component, Subaru water pumps are susceptible to wear and tear, and they may need to be replaced at some point during the lifespan of a Subaru vehicle.
What is a Water Pump?
A water pump is a critical component in a vehicle's cooling system. It is responsible for circulating coolant through the engine block, cylinder head, and radiator to help regulate the engine's temperature. The water pump is typically driven by the engine's serpentine belt and operates whenever the engine is running.
Why Do Subaru Water Pumps Fail?
There are a few common reasons why Subaru water pumps may fail over time:
- Wear and Tear: The water pump's impeller and bearings can wear down due to the constant rotation and pressure of the coolant flowing through the system.
- Corrosion: Exposure to coolant, which can be acidic, can cause the water pump's components to corrode and break down over time.
- Leaks: Seals and gaskets around the water pump can deteriorate, leading to coolant leaks that can cause the pump to fail.
- Overheating: If the cooling system is not functioning properly, it can cause the water pump to work harder and fail prematurely.
It's important to note that the lifespan of a Subaru water pump can vary depending on factors such as driving conditions, maintenance history, and the quality of the replacement part.
Signs of a Failing Subaru Water Pump
Some common signs that a Subaru water pump may be failing include:
- Coolant Leaks: Coolant leaking from the water pump or its surrounding components is a clear sign of a problem.
- Engine Overheating: If the engine is running hotter than normal, it could be a sign that the water pump is not circulating coolant effectively.
- Unusual Noises: A failing water pump may make whining, grinding, or squealing noises as the bearings or impeller wear down.
- Visible Damage: Cracks, corrosion, or other physical damage to the water pump's housing or components can indicate that it needs to be replaced.
If you notice any of these signs, it's important to have your Subaru's cooling system inspected by a qualified mechanic as soon as possible to prevent further damage to the engine.
How much does it cost to replace a water pump in a Subaru?

What are the symptoms of a bad water pump?
6 signs your water pump is failing
- Coolant Leak. The water pump has several gaskets that can be damaged or worn out over time.
- Engine Overheating.
- High Pitched, Harmonic Whining Noises.
- Water Pump Rust and Corrosion.
- Steam comes out from under your hood.
- Holes or leakage system on the dry side of the water pump.
At what mileage does water pump go bad?
100,000 miles
Car water pumps circulate coolant from the radiator to the engine block to prevent overheating and premature wear. Water pumps on modern cars often last more than 100,000 miles, while older models might need a replacement between 60,000 and 100,000 miles.
Will a bad water pump throw a code?
If your car's water pump goes out, one or more warning lights may pop up on the dash. For example, you may see the low coolant warning, overheat warning, or a check engine light.
Is it worth fixing a water pump on a car?
As discussed earlier, the water pump is one of the most important components for your car as it makes sure that your engine operates without interruption under perfect working temperature. It is imperative to keep a watch at its functional value to ensure that your engine does not undergo irreparable damages.
Can water pump last 200k miles?
The expected lifespan of a water pump is 60,000 miles to 90,000 miles, but many can last longer than that. Usually, once your car has reached the coveted 100,000 miles, you can plan on the need for a pump replacement soon.
How do I know if my Subaru water pump is bad?
For example, one common sign of a malfunctioning water pump is unusual noises coming from your Subaru's engine. More specifically, a squeaking, howling, or grinding noise may indicate that a water pump bearing has worn down, whereas a whining noise might signify a loose drive belt or broken water pump pulley.
