Hyundai Sonata Santa Fe Tucson Kia Sorento Optima Sportage G4KE 2.4L L4 Engine 2009-2011

Connecting rod bearing journal seizure from metallic machining debris accumulation destroys bottom end rotating components. The Hyundai Kia G4KE 2.4L Engine eliminates oil starvation hazards during commercial long block repower procedures. Delivering 175HP, this 2.4L 4-Cylinder assembly demands exact bellhousing dowel sleeve alignment to prevent transaxle input shaft bind upon chassis installation.

High strength ASTM A356-T6 cast aluminum forms the deep-skirt crankcase, housing an induction-hardened AISI 4340 forged steel crankshaft. This Hyundai Kia engine core utilizes tri-metal copper-lead bearings paired with stellite exhaust valve faces for thermal endurance under continuous load. Starter current draw measures 145A at 12V across cold bench verification. Dry weight totals 196 lbs within physical dimensions of 36in length, 36in width, 36in height, with a 4.8 quarts oil pan capacity.

Key Features of Hyundai Kia G4KE

Fleet operators buy Hyundai Kia G4KE long block assemblies to prevent catastrophic rotating assembly failure during industrial engine rebuild projects. Computer numerical control boring bars align the crank journals to eradicate micro-taper along bearing contact surfaces.

- Theta-2 K# cylinder head casting features square variable valve timing oil control passages.
- Dual continuous variable valve timing phasers optimize intake and exhaust valve overlap events.
- Crankcase casting stamped G4KE confirms authentic factory multi-port fuel injection architecture.
- High volume balance shaft oil pump assembly maintains continuous main journal boundary lubrication.
- The G4KE commercial core includes reinforced piston pin bushings to suppress wrist pin galling.
- Micro-polished crank journals establish uniform oil film retention under elevated cylinder pressure.
- Multi layer steel head gaskets eliminate combustion leak paths between adjacent cylinder bores.
- Viton valve stem seals resist high temperature hardening during stop and go fleet operation.

Dynamometer Output Tolerance Standards

Dynamometer testing documents 175HP at 6000 RPM and 169 ft-lbs torque at 4000 RPM across extended bench cycle profiles. Oil gallery operating pressure measures 55 PSI at a continuous oil sump temp of 195°F. Cylinder compression registers 185 PSI across all four cylinders with maximum allowable variance restricted below 4%. Crankshaft runout checks verify less than 0.0003in TIR along all five main journals. This G4KE long block engine maintains exhaust gas temp readouts below 1340°F during simulated hill climb cycles.

Chassis Application Platform Matrix

Direct bolt-in installation matches 2009 to 2010 Hyundai Sonata NF, 2009 to 2010 Kia Optima and Magentis MG, 2009 to 2012 Kia Rondo UN, and 2010 to 2011 Kia Forte TD platforms. It mounts direct to factory front wheel drive 5-speed automatic or 6-speed manual transaxles without bellhousing adapter plates or wire harness modification.

Field Installation Preventative Maintenance

Electronic throttle body calibration requires clean sensor ground circuits with under 0.2 ohms electrical resistance. Technicians must note this power plant is NOT engineered for direct injection GDI applications, turbocharged 2.0L platforms, or commercial motorhome conversions due to alternate oil pump configurations and lower cylinder block ribbing.

- Drain initial break-in petroleum motor oil after 500 road miles or 20 hours.
- Maintain cold mechanical valve tappet clearance at 0.008in intake and 0.011in exhaust.
- Clean the variable valve timing solenoid mesh filters during every second oil service.

Warranty Protection Crate Manifest

Protected by a 3-Year 100,000-mile parts warranty, each remanufactured assembly complies with strict Hyundai Kia assembly standard specifications. The reinforced freight crate contains the long block core, cast aluminum oil pan, front timing cover, valve cover, oil pump pickup tube, and signed dynamometer test documentation.
