Mini Cooper vehicles are defined by their compact BMW Group Engineering, requiring precise maintenance to sustain their efficiency. When your Cooper, Cooper S, or Countryman requires an engine replacement, you need a solution that restores factory specifications without the dealership premium.
At American Used Auto Parts LLC, we supply verified, expertly inspected used Mini Cooper engines for sale across the United States. We maintain a specialized inventory of Prince Engine (N12/N14/N16/N18) and newer B-Series (B38/B48) powertrains, offering a cost-effective way to extend the service life of your vehicle.
We are committed to technical accuracy, utilizing your VIN (Vehicle Identification Number) to distinguish between the N14 (2007-2010) and N18 (2011+) Turbo engines, which are not interchangeable.

We source used Mini assemblies exclusively from verified insurance auctions and dismantling partners. We utilize the VIN to confirm the engine generation, ensuring you receive the correct Valvetronic (N12/N16/N18) or Non-Valvetronic (N14) cylinder head configuration.
Base Models: We stock verified 1.6L Naturally Aspirated (N12/N16) units for the standard Cooper and Clubman.
S & JCW Performance: Sourcing for the widely used 1.6L Turbo (N14/N18) engines found in the Cooper S and Countryman S.
Modern Fleet: We maintain inventory for trusted 1.5L (B38) and 2.0L (B48) BMW-modular engines for F-Series Minis.
Our technicians focus on the known failure points of the Prince engine to prevent warranty claims.
"Death Rattle" Check (Critical): The N14 engine is notorious for timing chain tensioner failure, causing a distinct rattle on cold start. We inspect the chain tension and listen for this noise to filter out compromised units.
Carbon Buildup Inspection: On Direct Injection (Turbo) models, intake valves accumulate heavy carbon. We inspect the intake ports to verify the engine breathes correctly.
Thermostat Housing Check: We inspect the plastic thermostat housing for signs of coolant leaks, a common failure point that leads to overheating.
Compression Verification: We test cylinder pressure to ensure rings and valves are sealing within OEM tolerances.
To provide the best value, our engines are sold as Long Block Assemblies.
Included: Block, Cylinder Heads, Pistons, Crankshaft, Camshafts, Oil Pan.
Convenience Items: Accessories such as the High-Pressure Fuel Pump (HPFP), Turbocharger, and Vacuum Pump may be left attached for your convenience, but they are not covered under warranty. We highly recommend installing a new HPFP to guarantee reliability.
Don't let a timing chain failure or lost compression compromise your vehicle's value. American Used Auto Parts LLC makes the sourcing process transparent, secure, and technically accurate.
