Engine Replacement Cost Calculator

National planning ranges put a typical engine replacement between $2,000 and $10,000 (J.D. Power), with luxury and performance vehicles skewing higher. The real answer depends on the engine tier you choose: for a midsize sedan at an independent shop, this calculator estimates $1,990 – $6,540 installed for a used engine, $4,750 – $8,840 for a remanufactured unit, and $5,900 – $13,440 for a brand-new OEM crate engine. Labor, vehicle class, and shop rate move those bands up or down — run the calculator above with your exact setup instead of relying on a national average.

It is a trade-off between price, warranty, and risk. A used/salvage engine ($1,990 – $6,540 installed for a midsize sedan) is cheapest but typically carries only a 30–90 day parts-only warranty and unknown history. A remanufactured engine ($4,750 – $8,840 installed) is rebuilt to factory spec with new wear parts and usually a 3-year/100,000-mile warranty — the sweet spot for daily drivers. A new OEM crate engine ($5,900 – $13,440 installed) costs the most but arrives with zero miles and a full factory warranty. Choose used when the car's remaining value is low, remanufactured for a keeper, and OEM when the vehicle is late-model or under a warranty requirement.

Labor is the second-biggest cost after the engine itself. A straightforward swap takes 8–15 hours of shop time, and most U.S. independent shops charge $90–$150 per hour, so labor alone typically runs $1,100 – $1,540 for a midsize sedan at $110/hr. Complex jobs — turbocharged engines, V8 trucks, luxury cars with tight engine bays — can need 15–25 hours. Always confirm whether the quote is flat-rate or actual hours, and whether it includes diagnosis, fluids, and reprogramming.

The physical swap takes 8–15 labor hours for most cars, which usually means 1–2 days in the shop once the replacement engine is on hand. Sourcing the engine is the real variable: a common used or remanufactured 4-cylinder can arrive in days, while a rare, performance, or back-ordered OEM crate engine can take weeks. Ask the shop for two dates — when the engine arrives and when the bay is free — before committing.

Rebuilding (machining and reconditioning your existing block) typically costs $2,000–$4,500 and makes sense when the block and crankshaft are sound — it keeps your original engine with the car. Replacement wins when the block is cracked, the engine seized, or machine-shop time would exceed the cost of a remanufactured unit ($4,750 – $8,840 installed for a midsize sedan). Note that rebuild cost calculators estimate machine-shop work on your block; this tool estimates full swap cost with a different engine unit — compare both quotes for your failure type.

This is the classic repair-vs-replace gate. A head gasket repair typically costs $1,500 – $3,000, while a full replacement for the same midsize sedan runs $4,750 – $8,840. If the block and heads are straight and undamaged, the gasket repair usually wins by thousands — but if overheating warped the head or cracked the block, you are paying for the gasket job plus machining, and replacement becomes the safer money. Rule of thumb: repair when the damage is localized and the quote is under half the replacement cost; replace when the quote approaches replacement cost or the bottom end is hurt.

Use the 50% rule mechanics rely on: if one repair costs more than half the car's current market value, strongly consider selling. For example, a $1,630 – $5,620 — that is 70.3% of an $8,000 car, which lands in sell-it territory. Enter your car's honest private-party value (KBB or Edmunds, not a guess) in the calculator and it applies this gate automatically: under 40% means repair makes sense, 40–50% is borderline, over 50% means sell. Also weigh sentimental value and the cost of a replacement car against the repair.

No. The odometer is tied to the chassis (wheel/ABS sensors on modern cars), not the engine, so the mileage reading stays the same after a swap. What does reset is the engine's own life: a new or remanufactured unit starts at zero engine miles, which is why sellers must disclose an engine replacement — a low-mileage engine in a high-mileage chassis is a selling point, not a secret.

Warranty length tracks the tier. Used/salvage engines: typically 30–90 days, parts-only, and often void if you install it yourself. Rebuilt: about 12 months/12,000 miles. Remanufactured: commonly 3 years/100,000 miles, sometimes with labor allowance. New OEM crate: usually 3 years with generous mileage terms. Get the warranty in writing before paying, and confirm whether it covers labor for a second swap if the unit fails — a cheap engine with no labor coverage is the most expensive kind.

Budget $150–$700 in extras depending on vehicle class (this calculator includes them by default). The standard list: water pump, timing belt or chain kit, thermostat, motor mounts, accessory belts, hoses, spark plugs, fluids (oil + coolant), and filters. These parts are cheap while the engine is out and expensive later — a $60 water pump costs hundreds in labor once the new engine is installed. Ask for an itemized extras list with every quote.

Mechanically yes, practically it is a major project. The engine itself costs the same ($3,650 – $7,300 for a midsize remanufactured unit), but you save the $1,100 – $1,540 in shop labor — the trade is 40–60+ hours of your time, an engine hoist, a full tool set, torque specs, and a way to handle fluids and the old core. DIY also usually voids the parts warranty on used engines and all of it on reman units unless a certified shop installs them. Budget a full weekend-plus and a backup vehicle.

Trucks and V8 SUVs sit above the sedan range on both parts and labor: bigger castings cost more and the job takes 12–18 hours. At an independent shop this calculator estimates $2,380 – $7,880 installed for a used V8 and $5,620 – $10,580 for a remanufactured one. Diesel trucks are a separate league — remanufactured diesel long-blocks alone can exceed $10,000 before labor. Get truck quotes from shops that do heavy work regularly, not generalists.

For the same midsize sedan with a remanufactured engine, this calculator estimates $4,750 – $8,840 at an independent shop versus $5,645 – $10,300 at a dealership — the dealer premium comes from a higher labor rate (around $165/hr vs $110/hr) plus roughly 10% higher parts pricing. Dealers make sense for late-model cars under factory warranty or complex electronics; independents win on price for out-of-warranty vehicles. Get at least one quote from each.

Standard auto insurance does not cover mechanical failure or wear — a worn-out or overheated engine is maintenance, not a covered event. The exceptions: if the engine was destroyed in a covered accident, flood, or fire (comprehensive/collision), or you carry mechanical breakdown insurance (MBI), which is rare and usually limited to newer cars. Extended warranties and some certified pre-owned programs do cover engines — check yours before paying out of pocket.
