How Much Does Engine Replacement Cost?
Last updated: March 28, 2026 by the How Much Does That Cost? editorial team. Estimates are informational - see our methodology.
Engine replacement costs $2,800 to $7,500 for most cars and trucks, averaging around $4,800 installed. A used engine pulled from a salvage vehicle is the cheapest route, a rebuilt engine sits in the middle, and a brand-new crate engine from the manufacturer commands the highest price — often $8,000-$12,000+ for larger or turbocharged engines.
Labor is a major part of the bill: a full engine swap typically takes 15-30 hours, and shops often replace timing components, gaskets, and mounts while the engine is out, since those parts are far cheaper to address during the same job.

What Affects the Cost
Used vs. rebuilt vs. new
A used engine from a salvage yard costs the least but comes with the least certainty about remaining life. Rebuilt engines cost more but have worn parts replaced and tested. New crate engines cost the most but come with the longest warranty.
Engine size and configuration
Larger engines (V6, V8) and turbocharged or hybrid powertrains require more labor and more expensive parts than a standard 4-cylinder engine.
Make, model, and parts availability
Import and luxury vehicles often have pricier replacement engines and longer wait times for parts, which can raise both cost and shop time.
Labor hours and shop rates
An engine swap typically takes 15-30 hours of labor, and hourly shop rates vary widely between independent mechanics and dealerships.
Condition found during teardown
Once the old engine is out, shops often find that mounts, timing components, or accessories (alternator, water pump, turbo) also need replacing, which adds to the final bill.
DIY vs. Hiring a Professional
Doing it yourself
A full engine swap is one of the most advanced DIY jobs in auto repair, requiring an engine hoist, lift or jack stands, and real mechanical experience. Experienced hobbyists can save substantially on labor, but mistakes can be costly and dangerous.
Hiring a professional
A shop has the lift, hoist, and diagnostic tools to properly remove, install, and calibrate a replacement engine, and typically backs the job with a labor warranty in addition to the engine's own warranty.
Bottom line: For the vast majority of drivers, professional installation is the safer and more practical choice given the weight of the job, the risk of costly mistakes, and the value of a warranty on a major repair.
Ways to Save
- Get quotes from at least 2-3 independent shops in addition to the dealership.
- Consider a certified used or rebuilt engine with a warranty instead of a new crate engine.
- Ask a mechanic whether the issue is actually repairable (head gasket, timing chain) rather than requiring a full replacement.
- Buy from a salvage yard or supplier that offers a mileage or time-based warranty on used engines.
- Have other needed repairs (mounts, hoses, timing components) done in the same visit to avoid paying for labor twice.
How We Estimated This Cost

Frequently Asked Questions
How much does engine replacement cost?
Engine replacement averages about $4,800, with most jobs ranging from $2,800 to $7,500 depending on whether you choose a used, rebuilt, or new crate engine.
What is the difference between a used, rebuilt, and new engine?
A used engine is pulled from another vehicle with existing mileage. A rebuilt engine has been disassembled, machined, and had wear parts replaced. A new crate engine is entirely new, with the highest cost and longest warranty.
Is it worth replacing an engine or should I junk the car?
If the engine cost is roughly half or less of the car's market value and the rest of the vehicle is in good condition, replacement is usually worthwhile. On older, high-mileage vehicles it often makes more sense to sell or junk the car instead.
How long does an engine replacement take?
Most engine swaps take 3-7 days at a shop, including time to source the engine and complete 15-30 hours of hands-on labor.
What are the warning signs I need an engine replacement?
Persistent knocking or grinding noises, excessive smoke from the exhaust, significant oil consumption, overheating, or a compression test showing multiple failed cylinders are common signs a replacement — not just a repair — is needed.
