Understanding the Core 2014 chevrolet cruze rs specs
The RS package was available on the LT and LTZ trims, meaning it shares the same powertrain as those models but adds specific performance-oriented upgrades. The heart of the 2014 chevrolet cruze rs specs is the LUJ engine code, which signifies the 1.4L Ecotec turbocharged inline-four engine.
This engine was designed to provide a “downsized but boosted” experience, offering the power of a larger naturally aspirated engine with better fuel economy. It features a cast-iron block for durability and an aluminum cylinder head to keep weight down.
The Cruze RS engine horsepower is rated at 138 hp at 4,900 RPM. While that might sound modest, the real strength lies in the Cruze RS engine torque, which peaks at 148 lb-ft at just 1,850 RPM. This low-end torque makes the car feel punchy and responsive in city traffic.
Engine and Powertrain Details
- Engine Type: 1.4L Turbocharged Inline-4 (LUJ/LUV)
- Fuel System: Multi-port fuel injection (notably not a direct injection fuel system like later models)
- Compression Ratio: 9.5:1
- Valvetrain: Dual Overhead Cam (DOHC), 4 valves per cylinder
One of the most important things for a DIYer to know is the 5W-30 engine oil specification. Chevrolet requires Dexos1 certified oil for this engine to protect the turbocharger bearings from high-heat deposits.
Using a lower-grade oil can lead to premature turbo failure. Always ensure your oil filter is a high-quality unit, such as an ACDelco or equivalent, to maintain proper flow rates during cold starts.
Transmission and Drivetrain Configuration
The 2014 Cruze RS typically came with one of two gearboxes. Most units found on the used market feature the Hydra-Matic 6T40 automatic transmission fluid-cooled system, which provides smooth shifting for daily commuting.
For those who prefer more control, a 6-speed manual transmission was also available. The manual version allows drivers to stay in the turbo’s power band more effectively, though the automatic is generally more common for the LTZ RS configurations.
Maintenance for the automatic transmission is critical. While Chevy often lists the fluid as “fill-for-life,” experienced mechanics recommend a drain and fill every 45,000 to 60,000 miles to prevent solenoid sticking.
Chassis and Suspension Upgrades
The RS package includes more than just badges. It features a MacPherson strut front suspension and a Z-link rear suspension on higher trims. This setup reduces body roll and improves the car’s “planted” feel during cornering.
The RS also includes 4-wheel antilock disc brakes as standard. If you are performing a brake job, pay close attention to the slide pins, as they are known to seize in regions that use road salt during winter.
Wheel sizes for the RS package usually range from 16-inch to 18-inch alloys, depending on whether it’s an LT or LTZ base. The larger 18-inch wheels offer better grip but result in a slightly firmer ride over potholes.
Maintenance Essentials for the 2014 Chevrolet Cruze RS
Keeping up with the 2014 chevrolet cruze rs specs means following a strict maintenance schedule. Because this is a turbocharged engine, it is more sensitive to neglected maintenance than a standard 1.8L Cruze engine.
Spark plugs are a frequent maintenance item. The ACDelco 41-123 spark plug is the factory-recommended part. These Iridium plugs are gapped specifically to handle the cylinder pressures of a boosted engine.
If you experience a stutter or “chugging” under heavy acceleration, the ignition coil pack is the first place to look. These are known to fail, often due to moisture or heat-related stress on the rubber boots.
Critical Fluids and Capacities
- Engine Oil: 4.25 Quarts (4.0 Liters) of 5W-30 Dexos1
- Coolant: DEX-COOL coolant type (Orange), roughly 7.7 Quarts total capacity
- Brake Fluid: DOT 3
- Transmission Fluid: DEXRON-VI
Properly managing your cooling system is vital. You should regularly check your coolant reservoir maintenance levels, as the 1.4L engine is prone to small leaks that can lead to overheating.
The 2014 models often suffer from brittle plastic components in the cooling loop. If you see white crusty residue around your hoses, refer to a coolant hose layout to identify which part needs replacement before it bursts.
Common Issues and Diagnostic Tips
Even with the impressive 2014 chevrolet cruze rs specs, certain mechanical “weak points” emerged over time. Being aware of these can save you hours of frustration and hundreds of dollars in diagnostic fees.
The most common check engine light on this car is the P0299 turbocharger underboost code. This often points to a cracked wastegate housing or a failing bypass valve. It’s a common issue that often requires a turbocharger replacement to fix permanently.
Another frequent culprit for poor performance is the PCV (Positive Crankcase Ventilation) system. The PCV valve is actually integrated into the valve cover. When it fails, it creates a massive vacuum leak, causing a rough idle and whistling sound.
Symptom-to-Cause Diagnostic Table
| Symptom | Likely Cause | Recommended Action |
|---|---|---|
| Loss of Power / Limp Mode | Turbocharger Wastegate Failure | Check for P0299 code; inspect turbo housing. |
| Sweet Smell / Steam from Hood | Coolant Water Outlet Leak | Replace plastic water outlet with aluminum upgrade. |
| Rough Idle / Hissing Sound | PCV Valve Cover Failure | Replace the valve cover assembly immediately. |
| Jerky Shifting (Automatic) | Degraded Transmission Fluid | Perform a drain and fill with DEXRON-VI. |
If you encounter a coolant leak issue, don’t ignore it. These engines have very little tolerance for overheating, and a blown head gasket on a 1.4L turbo can often mean the engine block is warped beyond repair.
Visual and Aesthetic Features of the RS Package
What exactly makes a 2014 Cruze an “RS”? While the 2014 chevrolet cruze rs specs focus on the mechanicals, the visual upgrades are what define the trim for most buyers. The RS package was an “Appearance Package” that could be added to LT and LTZ models.
The front of the car receives a unique fascia with lower air dams and integrated fog lamps. Moving to the side, you’ll find rocker moldings that give the car a lower, more aggressive stance. These moldings are purely aesthetic but do a great job of making the car look sportier.
At the rear, the RS includes a decklid spoiler and a unique rear fascia. Inside the cabin, the RS package often includes an uplevel instrument cluster with chrome rings and an ice-blue backlighting that feels more premium than the base LS trim.
Interior and Tech Specs
- Infotainment: Chevrolet MyLink with a 7-inch color touch-screen
- Audio: Optional 9-speaker Pioneer premium sound system
- Safety: 10 standard airbags and StabiliTrak stability control
- Cargo: 15.0 cubic feet of trunk space (generous for the compact class)
For the DIYer, the interior is relatively easy to work on. The cabin air filter is located behind the glove box and should be changed every 15,000 miles to maintain HVAC airflow and air quality.
Performance Modifications and Tuning
Because the 2014 chevrolet cruze rs specs include a turbocharger, this car is a popular candidate for mild performance tuning. An aftermarket “tune” can safely increase the boost pressure, unlocking an additional 20-30 horsepower.
If you decide to tune your Cruze, you must upgrade your fuel to 91 or 93 octane. Higher boost levels increase the risk of “knock” or pre-ignition, which can destroy the small pistons in the 1.4L engine very quickly.
Upgrading the intake system and adding a larger intercooler can also help keep intake air temperatures down. This is especially useful if you live in a hot climate where heat soak can significantly sap the engine’s power during summer driving.
Pro Tip: The “Big Three” Upgrade
Many Cruze owners perform the “Big Three” electrical upgrade. This involves replacing the factory battery cables and ground wires with thicker gauge wire. This helps stabilize the voltage for the electric power steering and the ignition system, leading to smoother operation.
