Hyundai Kia G6DH 3.3L V6 Remanufactured Engine – 2012-2018

Description

Stop intake valve carbon buildup and connecting rod bearing starvation under 252 lb-ft continuous pulling across severe regional transit corridors through precision diamond plateau cylinder honing in the Hyundai Kia G6DH 3.3L Remanufactured Engine. Built for 2012 to 2018 commercial crossover platforms, this 24-valve gasoline direct-injection Lambda II powertrain outputs dependable acceleration and verified long-term mechanical stamina.

Featuring a 60-degree aluminum block with cast-iron cylinder liners, deck surfaces are milled to Ra 28 micro-inches to optimize cylinder head gasket retention. An induction-hardened forged steel crankshaft pairs with forged steel connecting rods and hypereutectic aluminum pistons with molybdenum skirt coatings. Equipped with cross-bolted four-bolt main bearing caps, a cast structural lower bedplate, a dry weight of 410 lbs, and a 5.5-quart oil capacity, this engine structure holds tight operating clearances under continuous load.

Key Features of Hyundai Kia G6DH

Commercial transport fleet supervisors buy Hyundai Kia G6DH 3.3L remanufactured engine packages to preserve mid-size utility vehicles without taking on new vehicle financing debt. Automated cold-spin testing verifies hydrodynamic bearing oil film retention across every single crankshaft journal before transport packaging.

• Gasoline direct injection cylinder head provides high fuel pressure atomization for complete combustion.
• Dual Continuous Variable Valve Timing continuously optimizes intake and exhaust camshaft duration.
• Multi-layer steel cylinder head gaskets maintain combustion containment during severe summer heat cycles.
• Cross-bolted four-bolt main bearing caps lock the forged crankshaft in true alignment under load.
• High-pressure internal trochoid oil pump feeds 60 PSI through clear block lubrication galleys.
• Dynamic mass balancing keeps harmonic rotating unbalance below 0.5 gram-inches.
• This Hyundai Kia G6DH crate motor matches factory six-speed automatic transaxle mount brackets.

Lambda Direct Injection Thermal Bounds

Engine lubrication maintains 20 PSI at warm idle and stabilizes between 55 and 70 PSI at 3000 RPM cruising speed. Coolant temperature operates from 185°F to 200°F via the primary thermostat circuit. The engine outputs 290 continuous brake horsepower at 6400 RPM and 252 lb-ft torque at 5300 RPM. An 11.5:1 compression ratio yields 180 to 195 PSI cranking compression across all six cylinders. Rated for Severe Commercial Fleet duty, radiator heat rejection reaches 4,050 BTU/min under continuous hauling.

Transaxle Interface Snout Dimensions

The rear crankshaft flange uses an 8-bolt flexplate bolt circle machined for automatic transaxles. Pilot bore diameter measures 0.826 inches with concentricity verified within 0.0008 inches to prevent torque converter pump wear. Front crankshaft snout measures 1.250 inches with a precision keyway, holding crank thrust endplay within 0.003 to 0.006 inches.

Priming Procedures Service Guidelines

Technicians must prime the lubrication channels using an external oil priming container through the oil pressure sensor port before initial starting. Fill with 5W-30 full synthetic motor oil and clear air from the cooling system using vacuum filling equipment. This powertrain is not engineered for forced induction turbochargers exceeding 5 PSI boost, nitrous systems, or racing competition.

• Check crankcase motor oil level and high-pressure fuel lines each shift.
• Change engine motor oil and filter every 3,000 miles or 100 hours.
• Inspect timing chain condition and serpentine belt tensioner every 12 months.

Commercial Warranty Crate Manifest

Protected by an extensive 3-Year / 100,000-Mile commercial fleet warranty covering parts and labor standards. Transport crate contents include the remanufactured long block engine, high-capacity oil pump, full vehicle installation gasket set, water pump inlet o-ring, pre-lube instruction sheet, and dynamometer cold-test validation reports.
