Product details

Casting numbers sit on the driver side of the block, which is where to look before ordering this 3.1L V6. The two casting lists in our record do not fully agree: the block casting field gives 093, 737, 089, 227 and 150, while the notes field gives 227, 150 and 253. Head casting is 234, and crank casting is 981 or 268. It is an OHV 12-valve engine listed for 2004-2005 Buick applications with VIN code J. Read the casting off your block and contact us if it falls outside those numbers.

2004-2005 Buick 3.1L V6. Block Cast #227, 150, 253. VIN Code J.

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.

Full details: our remanufacturing process and warranty terms. As an exchange unit a refundable core charge may apply.
