Quick answer. A full engine replacement in Southern California typically runs $3,500 to $8,500. A tested used engine lands at the low end. A remanufactured engine with a long warranty lands at the high end. The engine itself is roughly half the bill and labor is most of the rest.
Nobody plans for an engine to fail. It happens on the freeway on a Tuesday, the tow truck drops the car at home, and suddenly you are staring at the biggest repair decision most drivers ever face. We replace engines every week at our San Jacinto shop, from work trucks to commuter sedans, so the numbers below come from real jobs and not from a national cost calculator.
Almost every engine replacement quote falls into one of three buckets. Understanding the difference explains most of the price spread you will see between shops.
A running engine pulled from a wrecked or retired vehicle. This is the value play. A good dismantler compression tests the engine, documents the donor mileage, and stands behind it with a short warranty. We install used engines all the time and they can run for years. The key is sourcing. A 60,000 mile engine from a rear ended donor car is a great buy. A mystery engine with no paperwork is a gamble we will not take with your money.
A core engine that has been fully torn down, machined, and rebuilt to factory tolerances with new wear parts. Reman engines cost more up front but arrive essentially new inside, and the good builders back them with warranties of 3 years or 100,000 miles. For a vehicle you plan to keep a long time, this is usually the smart money.
Your engine comes out, gets torn down, and the failed parts are machined or replaced. This preserves a numbers matching engine and makes sense for classics and specialty vehicles. We have rebuilt everything from a 1967 Mustang 289 to modern Pentastar V6s. For a daily driver, a reman or used engine is usually faster and more predictable, because a teardown can uncover damage that grows the bill.
These are typical installed totals we see for common vehicles in Riverside County. Your exact number depends on the engine, the vehicle, and which option you choose.
| Scenario | Typical Installed Total | Notes |
|---|---|---|
| 4 cylinder sedan, used engine | $3,500 to $4,800 | Civic, Corolla, Altima class |
| 4 cylinder sedan, remanufactured | $5,500 to $7,000 | Best for long term keepers |
| V6 SUV or minivan, used engine | $4,200 to $6,000 | Pentastar, 3.5 EcoBoost class |
| V8 half ton truck, used engine | $4,800 to $6,800 | F-150, Silverado, Ram 1500 |
| V8 truck, remanufactured | $6,500 to $9,500 | Work trucks that must not fail |
| Diesel (Powerstroke, Cummins, Duramax) | $9,000 to $16,000+ | Heavy engines, long labor times |
| European luxury | $7,000 to $15,000+ | Parts cost and complexity |
Compare that to a dealership, where the same job is quoted at book time with labor at $180 to $220 per hour and list price parts. It is common for a dealer quote to come in 40 to 60 percent higher for the same engine.
An honest engine quote has four parts. When a quote looks suspiciously cheap, one of these is usually missing.
This is the real question behind every engine quote, and the math is simpler than it feels.
Say your paid off 2015 F-150 needs a $5,500 engine. The truck is worth $14,000 running and maybe $3,000 dead. Fixing it costs $5,500 and leaves you with a $14,000 truck you know the history of. Replacing it with something comparable costs $20,000 or more, plus taxes, registration, and higher insurance. Even financing the repair beats a $600 monthly payment within a year.
The math flips when the vehicle has other expensive problems stacking up. A slipping transmission, frame rust, or chronic electrical faults on top of a dead engine means you are restoring a vehicle, not repairing it. We tell customers honestly when a vehicle is not worth the engine, because we would rather lose one job than have you resent the bill.
Ask these before you authorize any engine replacement, from us or anyone else.
Supercanic tip. That last question matters most. We compression test, inspect the cooling system, and find the root cause before an engine goes in. A replacement engine deserves a vehicle that will not destroy it.
Plan on 3 to 7 days of shop time once the engine is in our hands. Sourcing adds time. A common used engine can arrive next day, while a specific remanufactured unit can take two weeks. We keep you posted at every step, and our engine replacement service includes a road test and a recheck before the keys come back.
Usually yes when the rest of the vehicle is solid. A $5,000 engine on a paid off truck beats $700 a month in payments. It stops making sense when the transmission, frame, or electronics are failing too. A good shop will tell you honestly which side of the line your vehicle is on.
Most jobs take 3 to 7 days once the replacement engine arrives. Sourcing the engine can add several days to two weeks. Tight engine bays, all wheel drive, and rusted hardware add time.
Never accept one without a written warranty. Junkyard engines often carry 30 to 90 days. Remanufactured engines commonly carry 3 years or 100,000 miles from the builder. Supercanic backs engine replacements with a 50,000 mile warranty.
It can be an excellent value when it is compression tested, has documented mileage, and comes from a reputable dismantler. The risk is unknown history. Ask for the donor mileage, a test report, and at least a 90 day warranty.
Shops quote different engine sources, labor rates range from about $120 to more than $220 per hour, and some quotes quietly leave out fluids, gaskets, mounts, and programming. Compare quotes line by line, never by the bottom number alone.
We diagnose the failure, quote every option in writing, and back the work with a 50,000 mile warranty.
