How Much Does a Used Engine Cost?

A blown engine doesn't have to mean the end of your vehicle. Used engines can save you thousands compared to new or remanufactured options — but only if you know what you're buying. Here's everything you need to know about used engine costs, where to buy, and whether it's worth it.

Average Used Engine Cost by Vehicle Type

The price of a used engine varies significantly based on the vehicle's make, model, engine size, and the mileage on the donor engine. Domestic vehicles tend to be cheaper than imports, and four-cylinder engines cost less than V6 or V8 options.

Below is a general breakdown of what you can expect to pay for a used engine — not including installation labor.

Vehicle Type	Used Engine Cost	Labor Cost	Total Estimate
Economy Car (4-cyl)	$500–$1,500	$1,000–$1,500	$1,500–$3,000
Midsize Sedan (V6)	$800–$2,500	$1,200–$2,000	$2,000–$4,500
Truck / SUV (V8)	$1,000–$3,500	$1,500–$2,500	$2,500–$6,000
Luxury / European	$1,500–$4,000	$2,000–$3,500	$3,500–$7,500
High-Performance	$2,000–$6,000+	$2,000–$4,000	$4,000–$10,000+

Used vs. Rebuilt vs. Remanufactured Engine: What's the Difference?

Before you buy, it's important to understand the three main types of replacement engines available on the market.

Used (Salvage) Engine

A used engine is pulled directly from a wrecked or retired vehicle at a salvage yard. It has not been rebuilt or reconditioned. These are the cheapest option but come with the most risk since you're buying an engine with an unknown history.

Rebuilt Engine

A rebuilt engine has been disassembled, inspected, and reassembled with replacement parts where needed. Quality varies widely depending on who did the work. Rebuilt engines typically cost $1,500–$4,000 and often come with a limited warranty.

Remanufactured Engine

A remanufactured engine is restored to original factory specifications using new or reconditioned parts. These are the most expensive option ($2,500–$6,000+) but offer the best reliability and usually come with a 1–3 year warranty.

Where to Buy a Used Engine

Knowing where to shop can save you hundreds of dollars and protect you from buying a bad engine.

Local salvage yards: Best for inspecting the engine in person before purchase. Prices are often negotiable.
eBay Motors: Large selection with seller ratings and buyer protection. Shipping costs can add $200–$500.
LKQ Corporation: One of the largest used auto parts networks in North America with consistent pricing.
Car-Part.com: Aggregates inventory from hundreds of salvage yards nationwide.
Local mechanics: Some shops have relationships with suppliers and can source engines at competitive prices.
Facebook Marketplace / Craigslist: Can find deals but carries higher risk — always inspect before buying.

What to Look for When Buying a Used Engine

Not all used engines are created equal. Before committing to a purchase, verify the following:

Mileage: Lower mileage is better. Aim for under 80,000 miles when possible.
Compression test results: Ask the seller if a compression test has been performed.
Oil condition: Check the dipstick. Milky or sludgy oil indicates internal problems.
VIN verification: Match the engine's VIN tag to the donor vehicle's records if possible.
Warranty: Even a 30–90 day warranty provides some protection.
Return policy: Reputable sellers allow returns if the engine doesn't work as described.

Is a Used Engine Swap Worth It?

The answer depends on the condition of the rest of your vehicle and the total cost of the repair versus the vehicle's market value.

A general rule of thumb: if the total repair cost (engine + labor) exceeds 70–80% of the vehicle's current market value, it may be time to consider replacing the vehicle instead. Use tools like Kelley Blue Book or Edmunds to check your vehicle's current value before committing to a major repair.

However, if your vehicle is otherwise in excellent condition — clean body, good transmission, new tires — a used engine swap can extend its life by 50,000–100,000 miles at a fraction of the cost of a replacement vehicle.

Hidden Costs to Budget For

The engine price is just the beginning. Budget for these additional expenses:

Engine mounts and gaskets: $100–$300
Timing belt/chain replacement (if not recently done): $200–$600
Coolant flush and refill: $50–$150
Oil and filter: $30–$80
Miscellaneous hardware and seals: $50–$200
Diagnostic fees: $100–$150

How to Save Money on a Used Engine

Smart shoppers can reduce the total cost of an engine swap significantly:

Get at least three quotes from different salvage yards and suppliers.
Ask about engines from insurance write-offs — these often have low mileage.
Consider a rebuilt engine if the price difference is small — the warranty is worth it.
Supply your own engine to a mechanic to save on markup.
Check if your vehicle is still under any powertrain warranty coverage.

Conclusion

A used engine can be an excellent value — but only when purchased carefully from a reputable source. Budget $1,500–$4,500 for most vehicles including labor, and always verify mileage, condition, and warranty terms before buying. If the numbers make sense, a used engine swap can keep your vehicle running for years at a fraction of the cost of buying another car.
