Chevy 3.9L V6 Remanufactured Engine – 2006-2007
Description
Propel loaded 3.9-liter fleet transport sedans up steep highway mountain grades under 180 PSI cylinder compression force without detonation through the Chevy 3.9L V6 Remanufactured Engine for 2006 to 2007 Chevrolet Impala models. This High Value LZ9 power plant features variable valve timing and active intake runners to produce strong passing power across regional highway corridors.
A high-nickel cast iron block features reinforced main bearing bulkheads and torque-plate honed cylinder bores. The micro-polished nodular cast iron crankshaft rotates inside tri-metal bearings linked to forged powdered metal connecting rods and hypereutectic pistons. Block decks meet an Ra 30 micro-inch finish. Total dry weight measures 390 lbs, matched with a 4.5-quart transverse steel oil pan.
Key Features of Chevy 3.9L V6
Fleet operators choose to buy Chevy 3.9L V6 remanufactured engine configurations to eliminate coolant consumption and restore full transport capability. Modern machining processes uphold uniform clearances across each internal friction surface.
- 0.0014-inch main bearing clearances preserve thick hydrodynamic lubrication under severe load demands.
- High-flow aluminum cylinder heads feature multi-angle valve seats to maximize volumetric efficiency.
- Hydraulic roller camshaft profile produces strong low-end pulling power across hilly highway routes.
- Multi-layer steel cylinder head gaskets prevent coolant migration into crankcase oil galleries.
- Precision hydraulic roller lifters eliminate valvetrain friction and maintain exact valve timing.
- Chevy 3.9L V6 high-output oil pump maintains continuous oil delivery across all engine galleries.
- Graphite-coated piston skirts eliminate cylinder bore scuffing during cold start cycles.
Dynamic Compression Operating Bounds
Oil pressure stays between 22 and 28 PSI at hot idle, climbing to 55 to 68 PSI under continuous highway loads. The cooling loop holds operating temperatures between 192°F and 205°F under demanding weather conditions. Power output reaches 242 horsepower at 6000 RPM and 242 lb-ft torque at 4400 RPM. A 9.8:1 compression ratio generates 175 to 195 PSI cranking compression, dissipating 2,500 BTU per minute.
Flywheel Flange Alignment Standards
A precision-machined 6-bolt flexplate flange aligns with GM transverse automatic transaxles without radial runout. Crankshaft endplay measures within 0.003 to 0.007 inches across thrust bearing surfaces. The front snout measures 1.250 inches with a machined Woodruff keyway to locate the harmonic dampener, sealed with an oil-resistant front crank seal.
Pre-Lube Setup Operational Restrictions
Mechanics must force engine oil through the main oil pressure port using an external priming pump prior to initial engine cranking. This long block is not engineered for turbocharger additions, superchargers, marine inboard propulsion, or vehicles operating past manufacturer gross vehicle weight ratings.
- Check motor oil level and radiator coolant reservoir each shift.
- Perform oil and filter service every 4,000 miles using 5W-30 motor lubricant.
- Examine serpentine belt tensioner, water pump, and radiator hoses every 12 months.
Warranty Statement Shipping Contents
A dependable 3-Year / 100,000-Mile commercial fleet warranty protects commercial operators from manufacturing and mechanical defects. Each wooden crate contains a remanufactured long block engine, high-capacity oil pump, full installation gasket set, and an official machine shop dimensional report.
