Engine Replacement Cost: Repair, Replace, or Sell?
A full engine replacement at a shop usually runs $3,000 to $7,000 — roughly $1,000 to $2,500 of that is labor, the rest is the engine. The cheapest path is a used engine you install yourself. The key decision: if the total cost is more than about half the car's value, selling it for cash usually beats fixing it.
Engine replacement cost by approach (2026)
Total job cost (engine + labor). DIY assumes you supply the labor.
| Approach | Typical total | Best for |
|---|---|---|
| Used engine + DIY install | $400 – $2,500 | Hands-on owners, older cars |
| Used engine + shop install | $1,800 – $4,500 | Lowest cost with a warranty option |
| Remanufactured + shop install | $3,500 – $7,000 | Longer warranty, newer cars |
| New (OEM) + shop install | $5,000 – $10,000 | Rarely worth it on older cars |
| Sell the car as-is | Instant cash | When repair exceeds ~50% of value |
Estimates for orientation — engine type, vehicle, and local labor rates change the numbers.
When to replace vs sell the car
Compare the total replacement cost to the car's value in good running condition. If the repair is more than about 50% of that value, you are usually better off selling the car for cash and putting the money toward a different vehicle.
A used engine swap on a car worth $5,000+ often makes sense. The same swap on a $2,000 car rarely does.
How to cut the cost
A used OEM engine from a salvage yard is the biggest saving — often 50% to 70% less than new. You can also supply your own engine to an independent shop, or pull and install it yourself if you have the tools and a hoist.
