Description

Several casting numbers here are recorded in shortened form: the left head as 12591207 and 81597, the right head as 12591206 and 81596, and the block as 12600129. Read the short entries as partial numbers and check the full stamping on your own engine rather than assuming they are complete. Coverage is the 2007 model year alone, across the Buick Allure, Lacrosse and Pontiac G6. This 3.6L is published without an engine code, so the castings and that single year are the match points.

2007 Chevrolet 3.6. Left Head Cast #12591207, 81597, Right Head Cast #12591206, 81596, Block Cast #12600129.

Every engine we sell is fully remanufactured to meet or exceed OEM specifications:

  • Deep Clean – To start the remanufacturing process, every engine is fully disassembled and hot tanked (cast iron) or thermally cleaned (aluminum)
  • Inspection – Magnaflux testing uses magnetic particles to inspect metal, checking for microscopic cracks and fissures that will cause long-term failure. All parts are visually inspected as well.
  • Machining and New Parts – Deck surfaces are CNC machined and new parts are added. New parts include bearings, pistons, rings, lifters, oil pump, gaskets, Viton™ valve seals, freeze plugs, galley plugs and either a new timing chain (with new tensioners) or a new timing belt (with new tensioner). If an engine has a timing-driven water pump, a new pump is installed.
  • SIM Testing – Each engine is SIM tested after reassembly, with the cooling and oil systems being fully pressurized and the crank being spun at high RPM to verify compression and build quality.

Every engine carries a 6-month limited warranty as standard. A 7-year / 1,000,000-mile extended warranty and a core-fee waiver are available on request for qualifying remanufactured units — ask us before you order and we will confirm eligibility.
