Used, remanufactured, or new — installed cost plus the fix-or-replace verdict
| Path | 4-Cylinder | V6 | V8 / Truck | Diesel | Typical 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 |
National installed ranges at a $130/hr independent-shop rate, parts low–high plus flat-rate labor hours (8–12 for four-cylinders, 10–14 for V6, 10–15 for V8, 12–18 for diesels). EV battery pack replacement is its own category: $5,000–$20,000 installed depending on pack size and whether it's a warranty-rate OEM pack, with only 3–6 hours of labor. Luxury and European vehicles add roughly 40–60% to parts. Dealership rates run $150–$190/hr.
An engine quote is two numbers multiplied out: the engine itself (which depends on the path you choose) and the labor to swap it (which depends on the engine's layout and your shop's rate). The calculator prices all three paths across the four common engine configurations, then runs the verdict math that actually decides the repair.
Installed cost = parts (low or high) + flat-rate labor hours × shop rate. The verdict compares the midpoint against the car's value after repair: under 30% is an easy fix, 30–50% is fix-after-audit, above 50% the money starts competing with a replacement vehicle. That's the same ratio a shop or claims adjuster applies, and it's why the same engine job makes sense in a truck and none at all in a tired sedan.
Pick your engine and path, set your local labor rate (independents run $100–$150/hr, dealers $150–$190), and enter what the car will be worth running. The ranges reflect national parts pricing; a specific salvage engine's price swings with mileage and availability, and reman prices swing with core charge and warranty length. If your quote lands far outside the range, the hours or the parts markup are usually where.
A 2016 Silverado with the 5.3L V8 needs an engine. Remanufactured path at $130/hr: parts $4,500–$7,000 plus 10–15 hours ($1,300–$1,950) = $5,800–$8,950 installed, midpoint $7,375. The truck's worth about $17,000 running, so the repair is 43% of value — inside the fix-after-audit band: check the transmission, brakes, and frame rails, then commit. A used 5.3 at the same rate would run $2,800–$6,450, but a 30–90 day warranty on a $17,000 truck most owners keep is a thinner bet.
Second example: a 2014 Camry 4-cylinder with a blown head gasket and 190,000 miles. Used engine at $130/hr: $800–$2,500 parts plus 8–12 hours ($1,040–$1,560) = $1,840–$4,060 installed, midpoint $2,950. The Camry's worth about $9,500 running, so the repair is 31% of value — right at the edge of the easy-fix zone, which is exactly why the used path (not a $5,500 reman) is the defensible choice in a car this age.
Installed, most engine replacements land between $2,000 and $10,000. A used 4-cylinder engine installed runs roughly $1,840-$4,060; a remanufactured V8 runs $5,800-$8,950 at typical labor rates; dealer-new crate engines for trucks and performance cars can pass $10,000-$14,000. Diesel engine replacement runs $8,000-$14,000 and EV battery pack replacement $5,000-$20,000. Labor alone is 8-18 hours at $100-$180 an hour.
Compare the installed cost to the car's value after the repair. Under 30% of post-repair value, fix it without hesitation. At 30-50%, fix it only after auditing the rest of the car — transmission, suspension, rust, tires. Above 50%, the repair is competing with the down payment on a replacement vehicle, and above 75% the car's next stop is a salvage yard. A $7,375 reman engine in a $17,000 truck (43%) is a keep; the same job in a $9,000 sedan (82%) is a walk-away.
Used ($1,800-$5,000 installed) fits older, lower-value cars where a 30-90 day warranty is acceptable and you're betting the salvage engine didn't live a harder life than yours. Remanufactured ($4,000-$9,000 installed for gas engines) is the value pick for a car you're keeping: internals rebuilt to spec with new wear parts and a 1-3 year warranty. New crate or OEM ($4,500-$14,000 installed) makes sense mainly for newer vehicles, diesels, or where a reman isn't available.
Almost never. Auto insurance covers sudden damage from covered events — a crash, flood, fire, or a rodent-chewed wiring harness — not mechanical failure or wear. If the engine died because the insurer's covered event caused it, you have a claim; if it threw a rod at 180,000 miles, that's yours. Mechanical breakdown coverage or an extended warranty can pick up failures, subject to its own terms and deductibles.
The book labor is 8-18 flat-rate hours depending on the engine and layout — transverse four-cylinders often take longer than they look, longitudinal V8s less. In practice, expect 2-5 shop days: the engine itself is a day or two of R&R, then fluids, seals, transfer of bolt-ons (intake, turbo, accessories), and any surprises discovered mid-job. Parts availability for used and reman units is usually the real bottleneck.
