Chevy Cobalt Malibu Pontiac G5 HHR LAP Ecotec 2.2L L4 Remanufactured Engine 12600E 2009-2010

Featuring an exact 2198cc displacement, this Chevy Cobalt LAP Ecotec Remanufactured Engine features Dual VVT camshaft phasers and factory smog provisions. Machinists line-hone the structural aluminum block and micro-polish crankshaft journals. Technicians must conduct complete cooling system vacuum bleeding and execute an exact 500-mile break-in oil change to protect the variable valve timing solenoids from debris.

Manufactured with a high-pressure die-cast aluminum block with cast iron cylinder sleeves, this Ecotec assembly features structural bedplate main bearing construction. The rotating foundation features a micro-polished forged steel crankshaft, forged powder metal connecting rods, and hypereutectic pistons with anti-scuff skirt coatings. DOHC 16-Valve cylinder heads receive diamond resurfacing for head gasket retention. Dry engine weight measures 240 lbs within crated dimensions of 36in length by 36in width by 36in height. Sump capacity equals 5.0 quarts.

Key Features of Chevy LAP Ecotec

Commercial fleet managers buy Chevy LAP Ecotec remanufactured engine long blocks to eliminate timing chain tensioner failures and restore strict exhaust emission compliance. This assembly provides factory-matched machine tolerances for transverse front-wheel-drive passenger car applications.

- Dual variable valve timing camshaft phasers undergo ultrasonic cleaning and bench testing for rapid advance response.
- Diamond plateau honed cylinder walls establish an Ra 14 micro-inch crosshatch finish for ring seating.
- Structural lower bedplate main tunnels undergo precision align-honing to prevent bearing clearance distortion.
- Micro-polished crankshaft journals eliminate runout to protect bi-metal engine bearings under load.
- Cylinder head smog passages undergo ultrasonic carbon cleaning to ensure secondary air injection compliance.
- Multi-layer steel head gaskets ensure combustion chamber seal integrity under elevated thermal operating cycles.
- Upgraded timing chain guides and hydraulic tensioners prevent chain slack and camshaft timing drift.

Dyno Load Operational Tolerances Specifications

Dyno cell testing validates internal oil gallery pressurization and power output prior to crate packaging. The 2.2L 2198cc DOHC engine produces 155 HP at 6,100 RPM and 150 ft-lbs of shaft torque at 4,800 RPM. Crankshaft main journal oil clearance holds between 0.0009in and 0.0013in, while connecting rod clearance measures 0.0010in to 0.0014in. Individual cylinder compression gauges verify 190 PSI across all 4 cylinders. Hot engine oil pressure maintains 55 PSI at 3,000 RPM with regulated coolant operating temperatures steady at 190°F.

Vehicle Fitment Drivetrain Guide

This long block repowers 2009 to 2010 Chevrolet Cobalt, 2009 to 2010 Chevrolet Malibu, 2009 to 2010 Chevrolet HHR, and 2009 to 2010 Pontiac G5 models equipped with the 2.2L LAP Ecotec engine with Dual VVT and smog air ports. Drivetrains require front-wheel drive. This unit does not fit earlier non-VVT L61 Ecotec engines, 2.4L LE5 platforms, or direct-injected 2.0L LNF turbo models due to cylinder head castings and camshaft sensor triggers.

Installation Protocol Service Requirements

Technicians must inspect secondary air injection check valves, bleed cooling air from the water pump housing, and verify variable valve timing actuator screens during installation. Operational warnings restrict use in custom forced induction turbo conversions exceeding 6 PSI boost or demolition derby vehicles lacking auxiliary oil cooling.

- Pre-fill the cartridge oil filter and prime engine lubrication passages with 5W-30 synthetic blend oil.
- Drain initial break-in oil and install a replacement oil filter at the 500-mile maintenance mark.
- Inspect variable valve timing solenoid connectors and check exhaust manifold nut torque at 1,500 miles.
