What is a water pump?
Your car’s water pump moves coolant through the system from the radiator to the engine and back again. The coolant absorbs heat from the engine, dissipates it through the radiator and remains in the system unless there is a leak.
If the water pump stops working, coolant stops moving and the engine can quickly overheat. Overheating can lead to a blown head gasket, warped engine parts or a cracked engine block, which may require a whole new engine.
Why a functional water pump is critical
Think of your water pump as your engine’s personal cooling assistant. Keeping it in good shape protects your car from overheating, saves you from big repair bills and helps your vehicle last longer.
Water pump warranty coverage
Unlike some automotive components that warranty providers exclude, water pumps are often included with basic powertrain coverage.
Factory warranty coverage
For context, a factory warranty, also called a manufacturer’s warranty, automatically comes with new vehicles. It typically includes bumper-to-bumper coverage, which covers most vehicle parts, and powertrain coverage, which covers parts like the engine and transmission. Bumper-to-bumper plans typically last around 3 years/36,000 miles while powertrain plans typically last around 5 years/60,000 miles.
Water pumps are often covered by powertrain warranties.
Whether a car’s water pump is covered under your factory warranty depends on how your manufacturer classifies it. Many auto manufacturers include the water pump with a powertrain warranty since it’s related to the engine. Other manufacturers include it with a bumper-to-bumper warranty, since it’s technically a cooling component and not an internal lubricated engine part.
Extended warranty coverage
Extended warranty providers sometimes include water pumps with basic powertrain coverage options, which are often the least expensive plan. Some companies may instead include it as a part of bumper-to-bumper or comprehensive coverage, or else offer it as a part of another parts group.
John, a reviewer from Illinois, said they saved $700 on a water pump repair with an extended warranty.

When is a water pump not covered under warranty?
If your water pump failure was caused by an excluded component, it might not be covered by an auto warranty. For instance, if a component like the thermostat, heater cores, hoses, pipes or valves fails and damages your water pump, it might not be covered. Still, it can sometimes be challenging to determine which component failed first, so a thorough diagnosis may be required to find out the cause.
For instance, George, a reviewer from New York, said: “My water pump broke, [which] damaged [a] pulley [and] a serpentine belt[.] [The] pump was covered, everything else was my cost.”
Auto warranties may also not cover water pumps if they determine that the vehicle didn’t receive regularly scheduled maintenance.
George, a reviewer from Wisconsin, said their extended warranty company denied their claim for a water pump repair because it claimed they didn’t get the coolant flushed after 100,000 miles. As a result, George said they had to pay $4,200 on water pump repairs.
Signs your water pump may be failing
If you notice any of these symptoms, it’s a good idea to have your mechanic check out your car.
- Engine is overheating: If your temperature gauge starts creeping into the red zone, or you see a warning light on your dash, your cooling system, which includes the water pump, might not be working properly.
- Coolant leaking under your car: Depending on the type of coolant used, if you see a green, orange, pink or blue puddle, it could be coming from the water pump.
- Grinding or whining noises: You might hear a high-pitched whining or grinding noise coming from the front of the engine.
- Steam coming from under the hood: If coolant isn’t circulating, the engine can overheat enough to cause steam to billow out, usually from around the radiator or under the hood.
- Build-up around the water pump: Rust, white-ish deposits or pitting near the water pump or its bolts could indicate a slow leak.
- Low coolant level: If you have to keep topping up your coolant, the water pump or another part of the cooling system might be leaking.
What is the average cost to replace a water pump?

A water pump should typically last between 60,000 and 100,000 miles with proper maintenance, though it’s possible it can last longer than that.
How urgent is a water pump replacement?
If your car’s water pump is failing, it should be replaced as soon as possible since it can damage the engine, which is a much more expensive issue.
