Which Honda has a K24 engine?
The K24 is Honda’s 2.4-liter K-series engine, and it appears in several models. The most common Hondas with a K24 are the Accord, CR-V, Element, and Acura TSX.
In this article, we explore where the K24 shows up in Honda’s lineup, how to identify it, and what to know if you’re shopping for a used car with this engine. The landscape centers on mid-2000s models, where the 2.4-liter K-series provided a balance of power and efficiency.
What is the K24 engine?
The K24 belongs to Honda’s long-running K-series family, a line of 2.4-liter inline-four engines introduced in the early 2000s. These engines are known for their broad torque delivery and efficiency, often featuring i-VTEC in many variants. Over the years, several variants were developed (such as A1, A4, Z-series, etc.), with refinements applied to performance and reliability across different model years.
Honda models commonly equipped with the K24
The following models have historically been equipped with K24 engines, making them the most recognizable options for buyers seeking this powerplant.
- Honda Accord (early to mid-2000s) — 2.4L K-series engine across various trims
- Honda CR-V (early to mid-2000s) — 2.4L K-series engine
- Honda Element (2003–2011) — 2.4L K-series engine
- Acura TSX (2004–2008) — 2.4L K-series engine (shared lineage with Honda’s K-series)
These years reflect common factory configurations; however, regional variations existed and engine codes differ by variant. When shopping, always verify the exact engine code on the engine block or the vehicle’s documentation to confirm you’re looking at a K24 variant.
Identifying a K24 and understanding variants
To confirm a K24 engine, look for the engine code stamped on the engine block or near the valve cover. Common indicators include “K24” in the code (for example, K24A4, K24A1, etc.), along with a variant letter. It’s also prudent to check the vehicle’s VIN and service records to ensure the engine matches the model year and trim sold by the manufacturer. Different variants (A1, A4, Z-series and others) denote incremental changes in intake, fuel delivery, and tuning, which can affect maintenance needs and parts compatibility.
What to know if you’re buying a used K24-powered Honda
While the K24 is generally regarded for a strong balance of reliability and performance, used examples require standard due diligence. Common considerations include verifying timing-chain condition (K-series engines use timing chains, not belts), inspecting for oil consumption trends on certain variants, and reviewing the water pump, tensioners, and thermostat as part of typical maintenance intervals. A thorough compression test, leak-down check, and a service history review are advised to assess longevity and potential head-gasket or gasket-related issues.
Summary
The K24 engine has powered several Honda and Acura models primarily in the 2000s, with the Accord, CR-V, Element, and TSX being the most recognizable examples. If you’re evaluating a used car for a K24, confirm the exact engine code and review maintenance history to understand variant-specific maintenance needs and reliability. While current Honda lineups rely on newer powerplants, the K24 remains a notable chapter in Honda’s engine family and a common find in well-used midsize and compact models.
