Hyundai G4KD engine for sale

Description

Hyundai G4KD engine is a 2.0-liter inline 4-cylinder gasoline engine originally manufactured in 2008 by Hyundai’s Theta II engine line. Designed keeping in mind the performance, fuel efficiency, and reliability, it has been highly used in numerous Hyundai and Kia models across vast segments.​

Technical Details

• Engine Model: G4KD​
• Cubic Capacity : 1,998 cc​
• Configuration: Inline 4-cylinder​
• Valvetrain: DOHC, 16 valves​
• Bore x Stroke: 86 mm x 86 mm​
• Compression Ratio: 10.5:1​
• Fuel System: Multi-point fuel injection
• Power Output: Approximately 150–165 hp at 6,200 rpm​
• Torque: Approximately 194–198 Nm at 4,300–4,600 rpm​
• Fuel Type: Gasoline (RON 92–95)​
• Emission Standards: Euro 4/5​
• Engine Weight: Approximately 124–136 kg​

Design and Features

The G4KD engine features an aluminum cylinder head and block, and this maintains the overall weight minimal and efficient cooling. It is equipped with a dual overhead camshaft (DOHC) setup with four valves per cylinder to ensure excellent airflow and combustion efficiency. It also features Continuously Variable Valve Timing (CVVT) on the intake camshaft to offer optimal performance and fuel economy across a broad range of engine speeds.

A timing chain system is employed for durability and lower maintenance compared to timing belts. The engine also incorporates a two-stage Variable Intake System (VIS) intended to maximize the delivery of torque across the RPM range.​

Applications

• The G4KD engine has been employed in numerous Hyundai and Kia models, which include:
• Hyundai Sonata (2008–2014)
• Hyundai Tucson/ix35 (2009–2015)
• Hyundai Elantra (different years)
• Hyundai i30 (different years)
• Kia Optima/Magentis (2008–2015)
• Kia Sportage (2010–2014)
• Kia Forte/Cerato (2008–2012)

Performance and Efficiency

The G4KD engine strikes a power and fuel economy compromise sufficient for day-to-day driving and freeway cruising. Fuel economy ratings vary with model and transmission but tend to be as follows:

• City: Approximately 9.3–11.2 L/100 km
• Highway: Approximately 5.6–6.9 L/100 km
• Combined: Approximately 7.0–8.5 L/100 km

Maintenance and Reliability

Extended life of the engines of the G4KD comes with appropriate maintenance. Suggested maintenance intervals include:

• Oil Changes: Every 7,500–15,000 km, using 5W-20 or 5W-30 synthetic oil
• Timing Chain Check: Around 150,000 km, but it’s for engine life​
• Valve Clearance Adjustment: Every 95,000 km, as the engine lacks hydraulic lifters​

Increased oil consumption and potential cylinder wall scratching are some of the prevalent problems quoted. These are normally caused by catalytic converter dust in the combustion chamber. Proper maintenance and inspection at the right time can cure these problems.

Conclusion

The Hyundai G4KD engine is indicative of Hyundai’s design to create a powerful and efficient power unit for a wide range of different types of cars. Its overall application on so many different models speaks volumes about its use and capacity for performance. Correct servicing and knowledge, as well as awareness of common faults, can allow the G4KD engine to operate for thousands of kilometers of useful life.
