Chevrolet Pontiac 2.2L L4 Remanufactured Engine – 1998 1072

Description

Meet strict commercial fleet maintenance benchmarks with 270 lbs of precision-machined cast iron powertrain engineering that outputs dependable four-cylinder pulling power and active thermal control throughout the Chevy Pontiac 2.2L 1072 Remanufactured Engine engineered for 1998 Chevrolet Cavalier and Pontiac Sunfire commercial fleet vehicles. This 1998-specific 8-valve OHV platform restores high fuel economy and dependable multi-shift service.

Cast from high-density gray cast iron, this 1998-specific 2.2-liter block incorporates revised cylinder head coolant ports and reinforced main bearing webs. A precision-ground nodular iron crankshaft turns within tri-metal bearings, linked to forged steel connecting rods and graphite-coated hypereutectic aluminum pistons. Decks receive an Ra 30 finish for MLS gasket sealing over diamond plateau honed bores. Dry mass measures 270 lbs with a 4.0-quart capacity stamped steel oil pan.

Key Features of Chevy Pontiac 2.2L 1072

Administrative fleet directors buy Chevy Pontiac 2.2L 1072 remanufactured engine packages to keep municipal utility sedans and administrative passenger cars running on strict operational schedules. Every remanufactured long block undergoes vacuum decay testing to guarantee total fluid circuit separation before crate departure.

• 1998-specific cylinder head casting ports match unique single-year intake manifold bolt patterns
• Sequential multi-port fuel injection optimizes air fuel charge distribution across all four combustion chambers
• In-block hydraulic roller camshaft profiles reduce valvetrain friction to enhance operational fuel efficiency
• 0.0010 to 0.0017 inch main bearing clearances maintain solid hydrodynamic lubrication film strength
• Multi-layer steel cylinder head gaskets maintain combustion seals across extreme summer city heat
• High-flow internal gear-type oil pumps channel pressurized lubricant to overhead pushrods and rocker arms
• Precision rotating package balancing protects Chevy Pontiac 2.2L 1072 driveline parts from vibration

LN2 1072 Operational Combustion Limits

Operating lubricant pressure produces 16 to 22 PSI during warm idle and expands to 45 through 60 PSI at 2600 RPM cruise speeds. Internal coolant temperatures stabilize between 190°F and 205°F using factory thermostat ratings. This 2.2-liter pushrod inline-four generates 115 horsepower at 5000 RPM and 135 lb-ft continuous torque at 3600 RPM with a 9.2:1 compression ratio. Cylinder cranking pressure measures between 165 and 180 PSI across all four chambers. The cooling system rejects 1750 BTU per minute during loaded highway transit.

LN2 1072 Crankshaft Transaxle Alignment

A 6-bolt rear crankshaft flange mounts flush to factory 4T40E automatic transaxle flexplates or 5-speed manual flywheels. Measured crankshaft thrust endplay checks out between 0.0030 and 0.0070 inches. The 0.984-inch front crankshaft snout features a single keyway to position the timing chain sprocket, holding true accessory drive serpentine belt pulley alignment.

LN2 1072 Fleet Servicing Protocols

Technicians must prime the engine oil pump prior to first startup by cranking the starter without ignition until oil pressure warning lamps extinguish. Fill the crankcase with 5W-30 motor oil meeting GM dexos standards. This production engine is not engineered for turbocharging conversions, nitrous injection, or competitive track racing.

• Check crankcase oil level and coolant tank fluid volume each shift before driving
• Drain break-in motor oil and install fresh oil filter after 500 initial miles
• Perform routine oil and filter changes every 3500 miles during commercial transit cycles

LN2 1072 Commercial Warranty Manifest

Commercial fleet purchasers receive a 3-Year / 100,000-Mile commercial fleet warranty covering structural casting and internal moving components. The heavy-duty wood crate contains one remanufactured long block engine, a complete engine install gasket set, spark plug well seals, front timing cover seals, dyno test documentation, and priming instructions.
