Is a water pump covered under warranty?

Water pump warranty coverage

Unlike some automotive components that warranty providers exclude, water pumps are generally included with basic powertrain coverage. For example, Endurance offers powertrain coverage through its least expensive Secure Plus plan and its documentation states that water pumps are protected under engine components. Similarly, CarShield’s most basic Silver plan covers water pumps, but unlike Endurance, it’s classified under the cooling system. CarChex also classifies the water pump as a cooling component, and its cheapest plan covers it.

While these parts are included in the coverages we mentioned, it’s important to note that a water pump failure caused by a noncovered component might not be paid for under the warranty. CarChex’s basic plan does not cover the thermostat, heater cores, hoses, pipes or valves, so if one of those components fails and damages your water pump, it might not be covered. That said, it can sometimes be challenging to determine which component failed first, causing the pump’s issues, so a thorough diagnostic will be required to find out the cause.

What types of warranties cover water pumps?

Most extended warranty providers include water pumps with basic powertrain coverage options, which are often the least expensive. But, while that’s a general rule, some companies separate water pumps individually or as part of another parts group. Olive covers the water pump in its basic powertrain plan, but it’s listed separately as a stand-alone item in its list of covered components. Again, remember that water pump coverage could depend on how it failed and on the causes of the failure, so if another component, such as the thermostat or hosing, fails and is not included in the coverage, you might be on the hook to pay for the water pump repair.

Does your extended warranty cover water pumps?

Most warranties cover water pumps in their most basic tier of protection, so you’ll likely be covered without spending extra money. Some limit water pump protection for specific vehicles, including those with higher mileage.

How much does it cost to fix your water pump?

Some water pump repairs are simple and can be completed for a few hundred dollars, while others are more complex and significantly more expensive. Depending on the job, you can expect to pay between $400 and $1,000, but remember that there’s always the “while we’re in there” tax, which could add to your total if other issues arise during the repair.
