Buick Riviera Remanufactured Engine
The Buick Riviera represents timeless luxury and American design excellence. From its dramatic 1960s curves to the sleek 1990s coupe, the Riviera remains a Buick icon. Its powertrain — typically the bulletproof 3.8L V6 — delivered strong, smooth acceleration. Over time, however, wear and tear can compromise performance. Gearhead Engines restores that classic Riviera experience with our fully remanufactured engines.
Each Riviera engine is completely rebuilt from the ground up. Engine blocks are magnafluxed and pressure-tested for integrity, cylinder heads are resurfaced, and every internal component is replaced or remachined. The result: an engine that performs like new and often outlasts the original.
For collectors and enthusiasts, a Gearhead remanufactured Riviera engine means you can enjoy your car for decades to come — without sacrificing originality. We even back our engines with a robust nationwide warranty and include free shipping on most gas engines.
