Typically about $500 to $900, depending on the engine and whether the timing belt kit is included. Higher costs apply to the V6 version or if OEM parts are used.
The 2004 Honda Accord offered two main engine choices: a 2.4-liter four-cylinder and a 3.0-liter V6. Because the water pump is usually accessed by removing the timing belt, the job often includes belt-related components and coolant. Prices vary by region, shop type, and whether you opt for OEM or aftermarket parts.
Cost by engine configuration
Prices vary by engine and whether the water pump replacement is performed as part of a timing belt service. Below are typical ranges and what drives them.
4-cylinder 2.4L engine
On 2004 Accords with the 2.4L four-cylinder, the water pump replacement typically involves removing the timing belt and may include replacing the timing belt kit, coolant, and related seals.
- Parts: Water pump typically $40–$120; timing belt kit $60–$170; coolant and miscellaneous supplies $10–$30
- Labor: Approximately 3–4 hours at typical shop rates of $80–$120 per hour
- Other possible charges: thermostat replacement or coolant flush if due, tax and disposal fees
Estimated total range for 4-cylinder models is roughly $450–$900, with most common prices falling in the $600–$800 range depending on location and shop.
3.0L V6 engine
For the V6 variant, a water pump replacement is generally more labor-intensive due to engine layout and extra components to access the pump.
- Parts: Water pump $70–$150; timing belt kit or equivalent on V6 may be required; coolant $10–$30
- Labor: About 4–6 hours at $90–$130/hour depending on shop and region
- Additional items: potential thermostat, radiator flush, overhead cover removal, and possible upper/lower coolant hoses
Estimated total range for the V6 is roughly $800–$1,200, with some cases reaching $1,400 in high-cost areas or if OEM parts are used.
What affects the final price
Several factors shape the final bill beyond engine layout.
- Carrier and model year specifics, and whether the pump is OEM or aftermarket parts
- Regional labor rates and shop type (dealer vs independent shop)
- Whether the water pump replacement is performed as part of a timing belt service and if a timing belt kit is included
- Coolant, thermostat, hoses, seals, and any needed coolant flush or tests
- Vehicle mileage and condition of related components (e.g., tensioners, idlers)
In practice, talking to a few local shops can help you dial in to the exact price for your Accord’s engine and the services chosen. Always request a written estimate that itemizes parts and labor.
Additional tips for getting the best value
Getting a reliable repair without overspending involves shopping around, asking for a belt kit, and confirming the price is inclusive of all required labor and taxes.
- Ask for a breakdown showing parts and labor separately and whether the belt kit is included
- Check whether the quote includes a coolant flush and thermostat if due
- Consider timing and scheduling services during off-peak hours for potential discounts
Note: Prices can vary significantly by location and shop, so use these ranges as a guide rather than a fixed quote.
Summary
Replacing the water pump on a 2004 Honda Accord generally costs between $500 and $900 for the 2.4L four-cylinder, and $800 to $1,200 for the 3.0L V6, with higher prices possible in regions with higher labor rates or when OEM parts and a full timing belt kit are specified. The majority of the cost comes from labor, while parts such as the pump and belt kit are a smaller portion. If your vehicle is due for a timing belt service, pairing the water pump replacement with the belt kit often provides best value and avoids future labor charges.
Can I still drive my car with a bad water pump?
Driving with a failing water pump is a gamble. Even if the car seems fine for a few miles, overheating can occur suddenly and without much warning. Once that happens, the damage can begin in minutes.
