The 2004 Honda Accord with a 2.4 L engine uses a 2.4-liter inline-four i-VTEC engine from Honda’s K-series family, typically the K24A4 in U.S. models.
It is a DOHC four-cylinder equipped with Honda’s i-VTEC variable valve timing system, designed to balance efficiency with on-demand power. Output is generally around 160–166 horsepower depending on trim and market, with roughly 160 lb-ft of torque. The exact engine code can vary by region, so checking the under-hood label or VIN is the best way to confirm the specific variant for a given car.
Engine family and variants
The 2.4 L engine in the 2004 Accord is part of Honda’s K-series, a family of reliable, high-revving four-cylinders. In many U.S. Accords, the engine is designated K24A4, though other markets used related K24 variants. The core characteristics are an aluminum block and head, a DOHC layout, and i-VTEC on the intake side for variable valve timing and lift.
How to identify the exact variant
To confirm the precise engine code for a specific vehicle, look for the engine code stamped on the engine block or consult the vehicle’s service manual, under-hood label, or the VIN/Monroney documentation.
Maintenance considerations
The K-series 2.4 L uses a timing chain rather than a timing belt, which generally lasts a long time but should be inspected for wear, tensioner health, and related components during maintenance. Regular oil changes with the recommended viscosity help keep the i-VTEC system functioning well. On higher-mileage examples, attention to water pump, thermostat, and chain tensioner becomes more important.
Summary
The 2004 Honda Accord’s 2.4 L engine is a 2.4-liter inline-four i-VTEC from Honda’s K-series, most commonly labeled K24A4 in the U.S. It delivers about 160–166 horsepower and around 160 lb-ft of torque, with a timing-chain design for durability. For the exact variant in a specific car, verify the engine code on the hood label or via the VIN.
