Engine replacement typically costs between $3,000 and $5,000 for a used engine installed at a shop, or $4,000 to $8,000 for a rebuilt engine with labor. New engines run $5,000 to $15,000 or more depending on the vehicle. The final bill depends on what kind of engine you choose, what your specific car is, and whether you use an independent shop or a dealership.

Key Takeaways

  • Used engines are the cheapest option but come with unknown mileage history, while rebuilt engines cost more but have been disassembled and inspected.
  • Labor costs for installation typically run $1,000 to $3,000 and vary by shop location, vehicle complexity, and how accessible the engine is.
  • Dealerships charge significantly more than independent shops for both parts and labor, sometimes double the independent shop price.
  • Additional repairs discovered during removal—like a failed transmission or damaged radiator—can add hundreds or thousands to your final cost.
  • Getting quotes from at least two shops before committing helps you understand the range for your specific vehicle and engine type.

What the three engine types cost

A used engine pulled from a salvage vehicle costs the least upfront: typically $800 to $2,000 depending on the make and model. The catch is that you do not know how the previous owner treated it or how many miles remain before failure. Used engines usually come with a short warranty—often 30 to 90 days—that covers only catastrophic failure, not normal wear. Shops source these from junkyards or online used-parts brokers.

A rebuilt engine has been taken apart, inspected, worn parts replaced, and reassembled to factory specifications. Rebuilt engines cost $2,500 to $4,500 for the engine itself. They typically carry a warranty of one to three years, which is longer than a used engine but shorter than a new one. Rebuilding is more reliable than buying used because you know the internals have been checked, but it takes time—a shop may need to order a rebuilt engine and wait for it to arrive.

A new engine from the manufacturer is the most expensive and most reliable option: $5,000 to $15,000 or more for the engine alone, depending on the vehicle. Luxury cars, trucks, and high-performance engines cost substantially more. New engines come with the manufacturer's warranty, usually three years or 36,000 miles. If your car is newer and still under warranty, the manufacturer may cover part or all of a replacement if the failure was a defect.

Labor costs and what affects them

Installation labor typically ranges from $1,000 to $3,000. The actual cost depends on three things: how long the job takes, the shop's hourly rate, and your location. A straightforward engine swap on a common vehicle like a Honda Civic might take 15 to 20 hours. A luxury car or a vehicle with the engine mounted sideways or buried under other components can take 30 to 40 hours or more.

Independent repair shops usually charge $75 to $150 per hour for labor. Dealerships charge $100 to $200 per hour. In high-cost areas like California or the Northeast, those numbers climb higher. A job that takes 20 hours at an independent shop in a mid-cost area might run $1,500 to $2,000 in labor alone. The same job at a dealership in an expensive city could easily exceed $3,500.

Before committing to a shop, ask for a labor estimate in hours, not just a dollar amount. That way you can compare the hourly rate and the estimated time separately. A shop quoting 25 hours at $100 per hour ($2,500) is not necessarily more expensive than one quoting 20 hours at $150 per hour ($3,000)—you need both numbers to judge.

Hidden costs that appear during the job

Once the engine is out, the shop may discover problems that were not obvious before. A failed transmission, a cracked radiator, a worn water pump, or corroded hoses often become visible only when the engine is removed. These repairs can add $500 to $2,000 or more to your bill. Some shops will call you before proceeding; others will fix them and bill you afterward.

Ask the shop upfront what their policy is: do they call you if they find additional work, or do they proceed and bill you? A reputable shop will contact you before spending money on anything beyond the quoted engine replacement. If you want to keep costs down, you can ask them to stop work and only replace the engine, leaving other repairs for later—though this is not always practical if a part is already removed.

Fluid replacements—oil, coolant, transmission fluid, and spark plugs—are usually included in the labor estimate, but confirm this. Some shops charge extra for premium fluids or synthetic oil. The difference is usually $50 to $200, but it is worth asking.

Independent shops versus dealerships

An independent repair shop will almost always cost less than a dealership for engine replacement. Independent shops typically charge 30 to 50 percent less for both parts and labor. A $5,000 job at an independent shop might cost $7,000 or $8,000 at a dealership.

The trade-off is that dealerships have factory-trained technicians, access to genuine manufacturer parts, and the ability to run factory diagnostics. If your vehicle is still under warranty, a dealership replacement may preserve that warranty, whereas an independent shop's work might not. Check your warranty documents or call the manufacturer before choosing a shop.

For older vehicles out of warranty, an independent shop with good reviews is usually the better financial choice. For newer vehicles still under warranty, a dealership may be worth the extra cost to keep your coverage intact.

How to get an accurate quote

Contact at least two shops and provide the same information to each: your vehicle's year, make, model, and current mileage. Tell them what kind of engine you want (used, rebuilt, or new) or ask what they recommend. Ask for a written estimate that breaks down the engine cost, labor hours and rate, and any other charges.

A good estimate will list the engine source (for example, "rebuilt Mitsubishi 4G64 engine from XYZ Rebuilders") and the warranty that comes with it. It will show labor as hours multiplied by hourly rate, not as a lump sum. It should note whether additional work discovered during removal will require your approval before proceeding.

Do not choose based on price alone. Read reviews of the shops on Google, Yelp, or the Better Business Bureau. A shop that is $500 cheaper but has poor reviews is not a bargain. Ask whether the shop guarantees its work and for how long—most reputable shops offer a one-year warranty on labor.

What to expect after replacement

After installation, the engine should run smoothly, but some new or rebuilt engines need a break-in period. The shop should tell you to avoid high RPMs and heavy acceleration for the first 500 to 1,000 miles. This allows the new parts inside to seat properly.

Keep your receipt and warranty paperwork. If the engine fails within the warranty period, contact the shop when ready. Most shops will cover the repair or replacement at no cost if the failure is due to a defect in the engine or installation. If you ignore warning signs—like knocking, overheating, or loss of power—and continue driving, the shop may deny the warranty claim.

Budget for an oil change at 500 miles and again at 1,000 miles if you chose a used or rebuilt engine. New engines may not need this, but check your paperwork. Regular maintenance after that—oil changes every 3,000 to 7,500 miles depending on your oil type—will help the new engine last.

Frequently Asked Questions

Is it worth replacing the engine or should I just buy a different car?

If your car is worth $8,000 to $12,000 and the engine replacement costs $4,000 to $5,000, replacement often makes sense. If your car is worth $3,000 and the replacement costs $6,000, buying a different used car is usually smarter. Compare the replacement cost to the car's current market value and how many years you plan to keep it.

Can I replace just part of the engine instead of the whole thing?

Sometimes. If only the head, block, or a specific component failed, a shop can rebuild just that part for less money. However, if the failure was catastrophic—like a seized engine or internal damage—replacing the whole engine is usually the only option. A diagnostic test will tell you which parts can be saved.

How long does engine replacement take?

Most jobs take three to seven business days from start to finish, including time to order parts if needed. A used engine in stock might be installed in two to three days. A rebuilt engine ordered from a supplier might take a week or more. Ask the shop for a timeline when you drop off your car.

Will my check engine light go away after replacement?

Usually, yes. The shop will clear the diagnostic codes after installation. However, if the light comes back on within a few days, it may indicate an installation problem or a separate issue with sensors or emissions components. Contact the shop when ready if this happens.

What if I cannot afford the full cost upfront?

Some shops offer payment plans or accept credit cards. Others may let you pay a deposit to hold your spot in the queue and pay the rest when the work is done. Ask about financing options when you get your estimate. Some credit cards offer 0% interest for a set period if you may have access to, which can make the cost more manageable.
