What is the part number for the Subaru water pump?
There isn't a single universal part number for Subaru water pumps. The correct number depends on your specific model, year, and engine.
Subaru uses model- and engine-specific part numbers. Different engines (EJ, FA, FB, etc.) and production years require different water pump identifiers, and pumps may be sold alone or as part of a timing belt or pump kit that has its own number. To ensure you get the right part, you should identify your vehicle’s engine code and VIN and look up the exact OEM number in the official catalog or through a dealer.
Understanding how Subaru assigns water pump numbers
Because Subaru changed designs across generations and engine families, the water pump part number varies by engine family, generation, and whether the pump is sold solo or as part of a kit. This means there is no single part number that fits all Subarus.
How to find the exact part number
Use the following steps to locate the correct OEM water pump part number for your Subaru.
- Gather vehicle details: model, year, engine code (for example EJ25, FA20, FB25), and VIN if possible.
- Enter or search by VIN in Subaru’s official parts catalog or a dealer portal to pull up the exact match for your car.
- Search specifically for “water pump” and verify whether the listing is for the pump alone or as part of a kit (timing belt kit, pump kit) that includes gaskets or bolts.
- Note the exact OEM part number and any revision suffix (suffixes such as -A, -B, etc. can indicate a newer design).
- If you’re considering aftermarket parts, compare compatibility with your engine code and confirm fit with the catalog or a parts advisor.
Concluding: By matching your engine code, model year, and VIN against the official catalog, you can retrieve the precise Subaru water pump part number for your vehicle. This reduces the risk of ordering the wrong part and ensures proper fit and function.
Practical tips for ordering
When ordering, verify whether the pump is sold as a standalone unit or as part of a kit, and check what hardware is included (gasket, bolts, seals). This helps avoid missing components that are required for installation.
- Prefer OEM or OE-replacement pumps to ensure compatibility with mounting points and impeller design.
- Cross-check the parts diagram to confirm you’re selecting the correct variant for your engine code.
Concluding: Always verify with the parts diagram and your VIN to avoid ordering mistakes, especially since Subaru has multiple pump designs across generations.
What to bring to a parts counter
Having the following information handy will speed up the lookup and ensure you get the correct part:
- Vehicle make, model, year, and trim
- VIN and engine code (e.g., EJ25, FA20, FB25)
- Any symptoms or notes (leak, noise) and whether you need the pump alone or as part of a timing belt/pump kit
Concluding: With precise details in hand, a parts advisor can quickly pull the exact Subaru water pump part number for your vehicle.
Summary
Bottom line: There is no single Subaru water pump part number that fits every model. To get the correct part, identify your engine code and VIN, then use the official Subaru parts catalog or a dealer to retrieve the exact OEM number for your vehicle, and confirm whether you need the pump alone or as part of a kit with gaskets and bolts. This approach minimizes ordering errors and ensures proper fit and function.
How do I know if my Subaru water pump is bad?
You can tell your Subaru water pump is bad by checking for coolant leaks, which may leave puddles under your car, or by listening for noises like whining, grinding, or squealing from the engine. Additionally, a rising temperature gauge or steam coming from the engine are critical signs of overheating caused by a failing pump.
Common signs of a bad water pump

- Leaks: Look for puddles of coolant (often green, but can be orange, pink, or blue) on the ground, especially in front of the engine. Discoloration around the water pump's "weep hole" is a specific indicator of a seal failure.
- Noises: Listen for new or unusual sounds, such as:
- Whining or groaning: Often gets louder with acceleration.
- Grinding: Can indicate a failing bearing.
- Squealing: This can happen if a failing pump causes the drive belt to slip.
- Engine overheating: If your temperature gauge is in the red zone or you see steam coming from under the hood, it's a critical sign that coolant is not circulating properly.
- Sweet smell: A sweet, syrupy smell can be noticeable if there's a coolant leak.
- Poor heater performance: If the heater blows cold air even when the engine is warm, it could be a symptom of poor coolant circulation caused by a bad pump.

How much does it cost to replace a water pump in a Subaru?
A Subaru water pump replacement typically costs between $400 and $800, but can range up to $1,500 or more depending on the vehicle, parts, and labor costs. Parts typically cost $200-$400, and labor can be just as much. The final price is heavily influenced by factors like your specific Subaru model, the type of water pump (belt-driven or electric), and the accessibility of the pump (which affects labor time).
Cost factors
- Vehicle model: Newer or more complex models may have higher repair costs. Some models, especially those with a timing belt, have more intricate water pump designs, increasing labor time.
- Parts: The cost of the water pump itself varies depending on the brand and whether it's an OEM or aftermarket part. The estimated range for parts is $200-$400.
- Labor: Labor is often a significant part of the total cost. The more your engine needs to be disassembled to reach the water pump, the higher the labor costs will be.
- Type of water pump: An electric water pump can be more expensive than a belt-driven one.
- Shop: Prices can vary between independent mechanics and dealerships. Dealerships often use manufacturer-recommended parts and have higher labor rates.
How to get an accurate estimate
- Contact multiple shops: Get quotes from both dealerships and independent mechanics to compare prices.
- Provide specific information: Give them your Subaru's year, make, model, and engine size to get the most accurate quote.
- Inquire about the "while-you're-in-there" parts: If your car has a timing belt, ask if the water pump is driven by it. If so, it is often cost-effective to replace the timing belt and other related components at the same time to save on labor costs.
