Hyundai Sonata Santa Fe Tucson Kia Sorento Optima Sportage G4KE 2.4L L4 Engine 2010-2011

Eliminate rod bearing knock and low oil pressure warnings with this Hyundai Tucson Kia Sportage G4KE Remanufactured Engine. Engineered for 2010 and 2011 crossovers, this 2.4L 4-Cylinder 16-Valve unit carries block casting G4KE with head casting THETA-2 K#. Technicians must verify proper timing chain oil jet clearance during install to prevent catastrophic link friction wear.

The structural die-cast aluminum block integrates high-strength iron cylinder liners under cylinder head casting THETA-2 K#. A precision-ground steel crankshaft rotates on premium tri-metal bearings inside align-honed main saddles. Dual overhead camshafts command 16 intake and exhaust valves via low-friction bucket lifters. Dry long block weight registers 250 lbs. The heavy crated envelope dimensions measure 36in length by 36in width by 36in height. The cast aluminum oil pan holds 4.9 quarts of motor oil.

Key Features of Hyundai G4KE

Professional auto technicians buy Hyundai G4KE remanufactured engine assemblies to restore customer vehicles to factory operating standards without dealership markups. This long block replacement provides precise cylinder head oiling for initial production dual variable timing systems.

- Block cast G4KE undergoes precision CNC line honing to establish exact main bearing clearances.
- Cylinder head casting THETA-2 K# features verified cam journal concentricity within 0.001in.
- Plateau-honed cylinder walls maintain cross-hatch depth for rapid piston ring bed-in.
- Micro-polished crankshaft rod journals hold 0.0003in TIR to prevent catastrophic bearing failure.
- Tri-metal engine bearings offer superior load capacity under high-temperature highway cruising.
- Multi-layer steel cylinder head gaskets create an impenetrable seal against compression leaks.
- Torque-to-yield cylinder head bolts provide uniform clamping load across all 4 combustion chambers.

Dyno Load Precision Machining Tolerances

Dyno load testing verifies 176 HP at 6,000 RPM and 168 ft-lbs of torque at 4,000 RPM on calibrated dynamometer cells. Crankshaft journal runout measures under 0.0003in TIR while rod bearing clearances check out at 0.0012in to 0.0016in. Diamond plateau cylinder honing creates a 12 to 16 Ra finish across all cylinder liners. Bench oil pressure testing verifies 58 PSI at 3,000 RPM at a stabilized 195°F coolant temperature. Individual cylinder compression verifies 185 PSI across all 4 cylinders for balanced power generation. Machinists calibrate valve lash to 0.008in intake and 0.012in exhaust to prevent valve float.

Vehicle Fitment Drivetrain Guide

This remanufactured long block fits 2010 to 2011 Hyundai Tucson built between production dates 10/20/09 to 1/11 and 2011 Kia Sportage built between production dates 4/10 to 1/11. Chassis match requires the 2.4L 2359cc engine code G4KE and head casting THETA-2 K#. Fits FWD and AWD drivetrains paired with 6-Speed automatic transmissions. This assembly does not fit later 2011 production models with round oil hole heads, 2.0L turbo variants, or GDI fuel systems.

Installation Protocol Service Requirements

Inspect electronic throttle position sensors and subframe engine mounts prior to installation. Technicians must flush the transmission oil cooler lines and replace the radiator assembly to prevent contamination from past engine debris. Do not install non-OEM superchargers or high-pressure turbocharger modifications on this stock compression long block.

- Pre-lube the engine by priming the internal oil passages with 5W-20 oil prior to initial ignition.
- Drain the initial break-in engine oil and replace the filter at 500 miles to clear particulate matter.
- Maintain routine synthetic motor oil changes at 3,000 miles to safeguard hydraulic cam phaser solenoids.

Warranty Terms Core Return Policy

This product includes a 3-Year Unlimited-Mile parts warranty for complete service assurance. Rebuilders receive full core credit upon return of the old engine core within 30-day terms via prepaid shipping. The shipping crate holds the remanufactured long block assembly, timing set, oil pan, valve cover, and quality inspection documents.
