* Used Engine Suppliers: This is likely your most realistic option. Search online for used engine suppliers specializing in diesel engines. Sites like eBay, Car-Part.com (which allows you to search by location and engine specifics), and various salvage yards may have listings. Be sure to carefully examine the seller's warranty and return policy before purchasing. Inspect the engine thoroughly (if possible) or request detailed photos and a compression test report.
* Diesel Engine Rebuilders: You might have better luck finding a rebuilt engine than a completely turnkey used one. Many diesel engine rebuilders can take your core (your old engine) and rebuild it to like-new condition. This is a more expensive route but can often provide a more reliable engine than a used one. Search for diesel engine rebuilders in your area or nationally.
* Specialty Truck Parts Suppliers: Some truck parts specialists focusing on older models or diesel trucks might have access to used engines or be able to guide you to a supplier. Check online for suppliers that focus on GMC Sierra parts.
Important Considerations:
* Year: Specifying the exact year of your GMC Sierra 3500 is crucial, as engine specifics changed over the years. The engine's compatibility with your truck is paramount.
* Warranty: Get a clear understanding of any warranties offered. Used engines rarely come with extensive warranties, but a reputable supplier should offer some protection against immediate failures.
* Shipping: Shipping a large engine like the 6.5L diesel can be expensive. Factor this into your budget.
* Installation: Even with a "turnkey" engine (meaning it's supposedly ready to install), you might still need some mechanical work to adapt it to your truck. Be prepared for potential installation costs.
Finding a turnkey 6.5L turbo diesel engine may require significant searching and patience. Start by contacting several suppliers and rebuilders to get quotes and assess your options.
