What size engine is in the Acura CSX?
The Acura CSX uses a 1.8-liter inline-four engine. It’s the familiar 1.8L i-VTEC unit shared with the Honda Civic on which the CSX was based.
The CSX was a Canada-specific compact sedan produced from 2006 to 2011. It was essentially a rebadged Honda Civic sedan tailored for Canadian buyers, slotting into Acura’s lineup as a practical, entry-luxury option rather than a high-performance model.
Engine size and configuration
The following specifications describe the CSX’s single engine option and how it powers the car. This helps explain why the CSX delivers everyday acceleration and efficiency rather than sport-focused performance.
- Engine type: 1.8-liter inline-four i-VTEC engine (Honda code R18A)
- Displacement: 1,795 cc (approximately 1.8 liters)
- Valvetrain: Dual Overhead Camshaft (DOHC) with i-VTEC
- Power output: around 140 horsepower
- Torque: around 128 lb-ft (173 Nm)
- Transmission options: 5-speed manual or 5-speed automatic
These figures reflect the CSX’s role as a dependable, economical sedan rather than a performance-focused vehicle. The engine’s 1.8L displacement balances responsive daily driving with reasonable fuel economy, aligning with the Civic-derived design philosophy.
Vehicle context
As a Canada-market model, the CSX bridged Acura’s luxury branding with Honda’s reliable engineering. Its powertrain mirrors what most Civic-based Acura variants used during that era, prioritizing smooth drivability, good fuel efficiency, and a comfortable ride over high horsepower figures. The 1.8L engine served as a predictable, widely serviceable option for buyers seeking practical performance in a compact luxury package.
Summary
In brief, the Acura CSX is powered by a 1.8-liter inline-four i-VTEC engine, producing about 140 hp and paired with either a 5-speed manual or 5-speed automatic transmission. This setup reflects the CSX’s Canada-specific, Civically rooted design and its focus on everyday usability rather than high-speed performance.
Is the Acura 2.4 engine reliable?
The Acura 2.4L engine, based on the Honda K24 series, is considered highly reliable, with many owners reporting high mileage with minimal issues, say Reddit and Facebook users. Potential issues include timing chain tensioner problems, oil consumption (more so in later K24Z versions), and, less commonly, cracked engine blocks in early K24A versions. Another point to consider is that some models with this engine, like the TLX, are paired with a dual-clutch transmission (DCT) which may require specific maintenance or updates, notes YouTube.
Reliability and common issues
- High reliability: The K24 engine is known for being "bulletproof" and is frequently praised for its durability. Many owners report reaching high mileage with no major engine problems.
- Maintenance is key: As with any engine, regular maintenance is crucial to achieve its long lifespan. Owners mention that proper care is essential to get the most out of the engine.
- Potential issues:
- Timing chain tensioner: Some K24 engines have documented issues with the timing chain tensioner.
- Oil consumption: Oil consumption can be a problem, especially in some of the later K24Z versions.
- Cracked blocks: Early K24A engine blocks have been known to crack, though this is less common.
- Model-specific considerations:
- Acura TLX: The 2.4L engine in the TLX is paired with a dual-clutch transmission. While the engine itself is reliable, the transmission may require maintenance. Some owners suggest issues can be mitigated by ensuring the car is properly warmed up or by getting software updates, say YouTube and Facebook users.
- Acura TSX: While the engine is reliable, some early TSX models (2004-2006, 2009) may have had issues with the engine, transmission, and brakes, recommend CarParts.com.
- Long-term ownership: The overall reliability is strong, with many owners keeping their cars well over 100,000 miles without major issues, according to Yahoo! Autos.
