Chevy 3.4L V6 Remanufactured Engine – 2000-2002

Description

Eliminate intake gasket failure and oil pressure drops under 60 PSI main gallery demand across heavy municipal transit duty cycles with the Chevy 3.4L V6 Remanufactured Engine for 2000 to 2002 front-wheel-drive chassis. This updated 3400 V6 platform incorporates revised lower intake sealing surfaces and roller rocker valvetrain hardware to maximize commercial uptime.

An engineered cast iron cylinder block undergoes precision line honing and diamond plateau cylinder honing to establish optimal oil retention. The nodular cast iron crankshaft turns inside tri-metal bearings connected to forged steel rods and graphite-coated hypereutectic pistons. Decks meet an Ra 30 micro-inch finish. Engine dry weight measures 372 lbs, utilizing a 4.5-quart transverse steel oil pan.

Key Features of Chevy 3.4L V6

Commercial fleet buyers choose to buy Chevy 3.4L V6 remanufactured engine packages to eliminate chronic coolant leaks and maintain dependable transport schedules. Advanced CNC machining standards preserve exact running clearances across all critical moving components.

• 0.0013-inch main journal clearances maintain durable hydrodynamic oil wedge protection under load.
• Upgraded multi-layer steel head gaskets stop combustion gases from entering engine cooling jackets.
• Hydraulic roller lifters paired with roller rocker arms reduce valvetrain friction and heat buildup.
• CNC-machined lower intake manifold mounting decks eliminate chronic coolant seepage into lifter valleys.
• Precision-ground valve stems seat tight against hardened valve seat inserts to prevent vacuum loss.
• Chevy 3.4L V6 gerotor oil pump provides continuous high-pressure oil flow to upper valvetrain pivots.
• Diamond-honed cylinder walls seated with moly rings stop blow-by and oil consumption.

Thermal Dynamics Dyno Ratings

Operating lubrication pressures span 22 PSI at hot idle to 65 PSI during continuous highway cruise speeds. Thermostatic cooling circuits regulate block heat between 192°F and 205°F across harsh weather extremes. Dyno validation confirms 180 horsepower at 5200 RPM alongside 205 lb-ft torque at 4000 RPM. A 9.5:1 compression ratio generates 165 to 180 PSI cranking compression, radiating 2,450 BTU per minute.

Driveline Interface Snout Dimensions

The rear crankshaft features a 6-bolt flexplate flange with a precision centering pilot hub for transaxle torque converters. Crankshaft thrust endplay gauges at 0.0035 to 0.0070 inches across ground thrust surfaces. The front snout measures 1.250 inches with a broached keyway to lock the front crank dampener against rotational vibration.

Break-In Mandate Excluded Usages

Technicians must pre-lube the engine with an external pump through the oil pressure port before cranking the starter motor. This powertrain package is not engineered for aftermarket superchargers, nitrous injection, marine inboard propulsion, or vehicles operating past manufacturer gross vehicle weight ratings.

• Inspect crankcase oil dipstick level and coolant expansion tank volume each shift.
• Change engine oil and install a new spin-on oil filter every 4,000 miles.
• Inspect cooling fan operation, radiator hoses, and serpentine drive belt every 12 months.

Fleet Coverage Shipping Contents
