How much does it cost to replace a crankshaft?

The cost of replacing a crankshaft varies significantly depending on the vehicle model, engine type, and repair location, generally ranging from 3,000 to 20,000 yuan. This is determined by several factors:

1. Price of the crankshaft

The original crankshaft for an average family car typically costs between 2,000 and 8,000 yuan, while the crankshaft for a high-performance or luxury car can exceed 10,000 yuan. Aftermarket or refurbished parts are cheaper, but may not offer the same quality or durability as the original.

2. Labor

Crankshaft replacement requires engine disassembly, which is time-consuming. A typical repair shop charges 2,000 to 5,000 yuan, and 4S dealerships may charge even more. For complex engines like V6 and V8 engines, the labor cost can reach over 8,000 yuan.

3. Cost of Additional Parts

Crankshaft replacement typically requires replacing connecting rod bearings, main bearings, piston rings, gaskets, and other components, costing approximately 1,000 to 3,000 yuan.

4. Vehicle Type Impact
The total cost of replacing a crankshaft for an economy car (such as a Volkswagen or Toyota) typically ranges from 5,000 to 10,000 yuan, while for a luxury or performance car (such as a BMW or Mercedes-Benz), it can be between 15,000 and 30,000 yuan.

If a damaged crankshaft causes damage to other engine components (such as the cylinder block or piston), repair costs can increase significantly. It's recommended to use a reputable repair shop and prioritize genuine or high-quality parts to ensure long-term, stable engine operation.
