"You need an engine" arrives with a five-figure fog around it, because nobody tells you it has three prices. The same car can leave the shop $2,000 lighter (a solid salvage unit) or $11,000 lighter (a dealer crate engine). Here are the national ranges for every path, what moves them, and the ratio that decides whether you fix the car or replace it.
National installed ranges for a mainstream vehicle at independent-shop rates ($130/hr). Trucks add 10-20%, luxury and European vehicles 40-60%:
| Path | 4-Cylinder | V6 | V8 / Truck | Diesel | Warranty |
|---|---|---|---|---|---|
| Used / salvage | $1,840 – $4,060 | $2,500 – $5,320 | $2,800 – $6,450 | $5,060 – $9,840 | 30 days – 1 yr |
| Remanufactured | $4,040 – $6,060 | $4,800 – $7,320 | $5,800 – $8,950 | $8,060 – $13,340 | 1 – 3 yrs |
| New crate / OEM | $5,540 – $8,560 | $6,300 – $9,820 | $7,300 – $11,950 | $10,560 – $16,340 | 2 – 5 yrs |
Labor is the quiet constant under every row: removing and reinstalling an engine runs 8-12 flat-rate hours on a four-cylinder, 10-14 on a V6, 10-15 on a V8, and 12-18 on a diesel pickup — $1,000-$3,000 at prevailing rates before a single part arrives. Transverse (sideways-mounted) four-cylinders often take longer than they look; a longitudinal V8 rolls out cleaner.
The two categories the table doesn't cover: EV battery packs (the EV equivalent of an engine) run $5,000-$20,000 installed, though with only 3-6 hours of labor — it's the pack that costs, not the swap. And hybrid battery packs run $1,500-$5,000, which is why aging hybrids often get a second life with a refurbished pack.
The ratio mechanics use: installed cost against the car's value after the repair.
Worked example: a 2016 Silverado 5.3L V8 needs a reman engine. At $130/hr that's $5,800-$8,950 installed, call it $7,375 at the midpoint. The truck's worth $17,000 running, so the repair is 43% of value — a fix, after checking the transmission fluid and frame rails. The same $7,375 in a $9,000 sedan is 82% — that car's next stop is the salvage yard, and its value as-is is what your junk car value calculator number becomes the floor for the next negotiation.
Budget 10-15% over any quote for the honest version of these, and ask the shop directly which of them they've included.
The salvage path has its own due diligence: buy from a recycler who reports the donor's mileage (Car-part.com listings show it), insist on a compression test or at least a warranty that survives installation, and have the installing shop replace the rear main seal and inspect the oil pan before the engine goes in — a $30 seal is an engine-out job to fix later. And keep every receipt: a documented engine swap is the only version of one that pays you back at resale.
Engine type, path, shop rate, and your car's value — get the installed range, the midpoint, and the fix-or-walk verdict in one screen.
Engine Replacement Cost Calculator →A full in-frame or out-of-frame rebuild on a worn engine often prices close to a remanufactured unit ($3,000-$6,000) but carries the risk that the block or head has damage discovered mid-job. Replacement with a reman usually wins unless the engine is rare, the car is collectible, or a rebuild addresses a single known failure (a head gasket on an otherwise healthy engine is a $1,500-$2,500 job, not a rebuild). Get the diagnosis before choosing a path.
The quote rarely includes everything that bolts to the new engine. Budget for: core charge on reman units (refunded when your old engine comes back), new seals, timing components, water pump and thermostat while it's out, fluids and filters, motor mounts, and often a new clutch or rear main seal on manuals. If the failure sent metal through the oil, the radiator, oil cooler, and lines may need flushing or replacement too. Expect $200-$800 of "while we're in there" parts on a clean job, more after a catastrophic failure.
No. The odometer reads the car, not the engine, and legally the title and disclosure follow the chassis — a car with a replaced engine is sold as 180,000 miles with a newer engine, which buyers do value, just not as a low-mileage car. Keep the receipts and the engine's documentation: they're the proof that makes the swap worth anything at resale.
