How much does it cost to replace an entire car engine?

Replacing a car's engine typically costs between $3,000 and $7,000 when you install a used or remanufactured unit, and can exceed $10,000 for a brand-new crate engine, depending on the vehicle, location, and required ancillary work.

In practice, the total price depends on the engine source, the car's make and model, regional labor rates, and any additional parts or programming needed to get the vehicle back on the road.

Engine sourcing options and typical price ranges

Prices vary widely with the source of the engine. Here are common choices and what you might pay in typical U.S. shops as of 2025.

• Used/salvage engine: roughly $2,000–$5,000 total (engine plus labor). Warranties may be limited and compatibility with your car’s electronics can vary.


• Remanufactured/rebuilt engine: roughly $4,000–$7,000 total. These are rebuilt to factory specs and often come with extended warranties on parts and sometimes labor.


• New crate engine: roughly $6,000–$10,000+ total. Brand-new engines can require more extensive installation work and programming; some luxury or performance engines cost more.

Prices can be higher for turbocharged, diesel, or high-output engines, for modern vehicles with advanced electronics, or for rare models requiring specialized parts.

What factors most influence the final bill

Different elements in play can swing the total cost up or down. The list below highlights the main drivers you’ll likely encounter.

• Engine type and vehicle complexity: Turbocharged, V8 or diesel engines, or vehicles with complex electronics typically demand more labor and specialized parts.


• Labor rates and time: Typical labor time is around 6–12 hours for many cars, but complex vehicles can take longer. Regional shop rates commonly range from $80 to $150+ per hour.


• Additional parts and services: Water pump, timing kit, radiator, hoses, belts, sensors, wiring harness, exhaust components, transmission mount, and ECU reprogramming can add several hundred to a few thousand dollars.


• Core charges and shipping: Some engines come with a core deposit that is refunded when the old engine is returned; crate engines may incur freight or handling fees.


• Warranty and aftercare: Warranties vary by source (used vs remanufactured vs new) and by shop; longer coverage generally adds cost but can save money over time.


• Diagnostics and labor extras: Initial diagnosis, table alignment, and immobilizer programming can add to the bill if the car's electronics are intertwined with the engine control system.

To avoid surprises, obtain a written estimate that itemizes engine price, labor hours, and each component or service. Ask about warranty periods and what is covered if something fails after installation.

Is replacing the engine the best option?

For some vehicles, replacement makes sense; for others, repair or engine refurbishment may be a better bet. Consider total cost of ownership, expected remaining life of the car, and the availability of a salvage engine with a warranty. When in doubt, seek a second opinion from an independent shop and compare quotes before proceeding.

Summary

Engine replacement costs vary widely but generally fall into three broad ranges: $2,500–$5,500 for a salvage/used engine, $4,000–$7,000 for a remanufactured engine, and $6,000–$10,000+ for a brand-new crate engine, with labor often accounting for a large share of the total. Higher-end or specialty engines, diesel powerplants, and vehicles with advanced electronics can push costs higher. Always get a detailed estimate, consider warranties, and compare multiple quotes before proceeding.

Is it cheaper to replace or rebuild an engine?

Rebuilding an engine is often cheaper upfront than a full replacement, but replacement can be a better long-term investment, especially if a used or remanufactured engine comes with a warranty. The final cost depends on the extent of the damage, the vehicle's age and type, and the labor involved. 
Engine Rebuild

• Pros:
  • Lower initial cost: A rebuild is generally less expensive than buying a new or remanufactured engine, with costs often ranging from $2,500 to $4,500. 
  • Keeps original engine: This can be valuable for certain vehicles and may help retain its overall value. 
  • Can improve performance: A proper rebuild can restore and even improve the engine's performance and fuel economy. 
• Cons:
  • Hidden costs: The price can increase significantly if the initial inspection fails to identify deeper, more expensive damage that is discovered once the engine is disassembled. 
  • No warranty: Rebuilt engines may not come with a warranty, or the warranty may be limited. 
  • Time-consuming: A rebuild takes time, and you may need to account for rental car costs if you need transportation while the work is being done. 

Engine Replacement

• Pros:
  • More reliable: A new or remanufactured engine often comes with a warranty, providing a safety net and peace of mind. 
  • Less risky: A replacement engine is a fully functional unit, avoiding the risk of discovering more damage during the rebuild process. 
• Cons:
  • Higher upfront cost: The initial price is steeper, with costs ranging from $4,000 to over $8,000, depending on the engine type. 
  • Used engine gamble: A used engine can lower the cost, but it also carries the risk of unknown history and potential future problems. 

Which option is right for you?

• Choose a rebuild if: The engine damage appears minor, you want the most cost-effective option upfront, and you are willing to accept a higher risk of additional costs.
• Choose a replacement if: The engine is severely damaged, you prioritize long-term reliability and a warranty, and you are willing to pay more for peace of mind. 

How much does a V8 engine cost?

Brand-new V8 engines can vary from $2,000 to over $10,000. The V8 engine cost is highly based on the engine's specifications and the vehicle for which it is designed.

How much does it cost to replace a whole car engine?

Engine Replacement Cost
On average, drivers can expect to pay between $5,000-$10,000 for an engine replacement. Of course, costs can vary based on a few factors. The two most common factors that will influence the overall cost of the replacement are vehicle type and new or used engine. Low Cost: $600.

Is it worth replacing the engine in a car?

Replacing an engine is worth it if the car is in otherwise good condition, the repair cost is significantly less than buying a new car, and the car has sentimental or other value beyond its resale price. However, it is often not worth it for older vehicles, cars with significant rust or other problems, or if the replacement cost approaches the vehicle's market value.

When it is worth it

• Your car is relatively new or in excellent shape: If the rest of the vehicle is in good condition, a new engine can extend its life significantly. 
• You have sentimental value for the car: If it's a family heirloom or has a special meaning, replacing the engine can be a good way to keep it running. 
• The cost is much lower than a new car: For many people, replacing the engine is a more affordable way to get a reliable vehicle than buying a new one. 
• Your vehicle is under warranty: If your car is still under warranty, the engine replacement will likely be covered at little or no cost to you. 
• Insurance will cover the cost: If your insurance policy covers the replacement, it can be a very cost-effective solution.

When it may not be worth it

• The car is old or in poor condition: If the vehicle is 15-20 years old or has significant rust and other issues, the cost of a new engine might not be a good investment. 
• The engine replacement cost is too high: A major engine swap can cost anywhere from $5,000$ 5 comma 000$5,000 to over $10,000$ 10 comma 000$10,000, so if this cost is close to or exceeds the car's value, it may not be worthwhile. 
• Other major components are failing: If your car's transmission, or other major parts have high mileage, they may need replacement soon, adding to the overall cost. 
• The engine failure was due to neglect: If the engine failed because of neglect, the rest of the car might be in poor condition and also require extensive repairs. 

Alternatives to replacing the engine

• Rebuild the engine: Rebuilding can be a cheaper option, but it's not always guaranteed and might not be as reliable as a replacement engine. 
• Buy a different used car: If the car is older and needs a lot of work, it may be cheaper to buy a different used vehicle. 
• Junk the vehicle: If the car is too old and expensive to repair, it may be better to sell it for scrap and buy a new one.
