Chevy 2.8L V6 Remanufactured Engine – 1985-1986 FWD

Description

Command 130 horsepower and 2.8 liters of displacement while holding coolant temperatures below 200°F across tight city streets inside the Chevy 2.8L V6 Remanufactured Engine for 1985 to 1986 front-wheel-drive platforms. This transverse-mount iron-head engine delivers responsive low-end pull to sustain stop-and-go commercial parcel transport without engine overheating.

A 60-degree high-nickel cast iron block features siamesed cylinder bores plateau-honed to a 45-degree angle. The micro-polished nodular cast iron crankshaft spins on precision tri-metal bearings linked to forged steel connecting rods and aluminum alloy pistons. Block deck surfaces exhibit an Ra 35 micro-inch finish. Total engine dry weight equals 355 lbs, serviced by a 4.0-quart front-wheel-drive oil pan.

Key Features of Chevy 2.8L V6

Fleet buyers prefer to buy Chevy 2.8L V6 remanufactured engine assemblies to restore dependable power on vintage front-wheel-drive corporate vehicles. Strict machine shop practices guarantee uniform tolerances across all reciprocating and rotating parts.

• 0.0013-inch connecting rod bearing clearance prevents journal galling during heavy low-gear acceleration.
• Deep-seated valve guides prevent oil leakage past intake valve stems into combustion chambers.
• Transverse-specific cast iron cylinder heads route coolant flow across hot exhaust valve bowls.
• Precision hydraulic lifters eliminate valvetrain noise and maintain constant valve lash settings.
• High-tensile head bolts clamp graphite head gaskets flat to eliminate compression leakage.
• Chevy 2.8L V6 internal oil passages undergo ultrasonic cleaning to flush out metal machining swarf.
• Phosphate-coated camshaft lobes resist initial friction wear during critical early break-in periods.

Thermal Profiles Compression Limits

Hot engine idle oil pressure registers between 18 and 24 PSI, climbing to 45 to 60 PSI at 2500 cruising RPM. Engine cooling passages maintain operating temperatures from 188°F to 200°F under summer load. Output peaks at 130 horsepower at 4800 RPM and 155 lb-ft torque at 3600 RPM. An 8.9:1 compression ratio generates 150 to 165 PSI cranking compression, with 2,200 BTU per minute of heat transfer.

Transverse Crankshaft Transaxle Interface

The transaxle mounting face features an internal balance 6-bolt flexplate pattern for transverse GM automatic transaxles. Crankshaft thrust endplay measures 0.003 to 0.007 inches at the center thrust bearing. The front snout measures 1.250 inches with a standard square-cut keyway to secure the front accessory drive pulley without vibration.

Lubrication Prep Prohibited Usages

Mechanics must prime internal oil galleries through the distributor drive hole using an external drill-driven pump before starter engagement. This powertrain is not engineered for marine marine inboard use, high-boost supercharging, stationary continuous pump drives, or vehicles exceeding gross vehicle weight limits.

• Inspect oil stick level and radiator recovery bottle coolant volume each shift.
• Drain engine oil and change the oil filter every 3,500 miles.
• Inspect serpentine accessory belts and cooling system hose clamps every 12 months.

Warranty Coverage Crate Manifest

A dependable 3-Year / 100,000-Mile commercial fleet warranty covers internal mechanical components and machinework. The package contains a remanufactured long block, high-pressure oil pump, complete install gasket set, valve cover seals, water pump gasket, and a final quality inspection clearance document.
