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.
Key Points
- Used engine installed usually runs $3,500 to $5,500. Remanufactured usually runs $5,500 to $8,500. Diesel and luxury engines go higher.
- Labor is 10 to 20 shop hours. Supercanic engine swap labor starts at $1,800. Dealer labor for the same job can pass $4,000.
- A written warranty is not optional. Supercanic backs its engine replacement labor for 90 days or 5,000 miles, and names the engine’s own supplier warranty on the quote.
- Replacing an engine on a paid off vehicle is usually far cheaper than replacing the vehicle.
- Get every quote itemized. The cheap quote is often missing fluids, mounts, gaskets, and programming.
Engines rarely give much warning. The car quits, a tow truck drops it at home, and you are looking at one of the biggest repair bills a vehicle can hand you. We replace engines every week at our San Jacinto shop, on work trucks and commuter sedans alike, and the numbers below come from those jobs.
The Three Ways to Replace an Engine
Almost every engine replacement quote falls into one of three buckets, and knowing which one a shop quoted explains most of the price gap between shops.
1. Used Engine From a Dismantler
A running engine pulled from a wrecked or retired vehicle, and the cheapest way back on the road. 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, as long as they come from a good source. A 60,000 mile engine from a rear ended donor car is a great buy. We won't install a mystery engine with no paperwork.
2. Remanufactured Engine
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 the one we usually recommend.
3. Rebuilding Your Own Engine
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.
What Engine Replacement Actually Costs
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.
Where the Money Goes
An honest engine quote has four parts. When a quote looks suspiciously cheap, one of these is usually missing.
- The engine itself. Roughly $1,200 to $3,000 used, or $2,800 to $5,500 remanufactured for common vehicles.
- Labor. Removal and installation is 10 to 20 shop hours depending on the vehicle. Our engine swap labor starts at $1,800, quoted exactly in writing before any work begins. Transverse V6s in tight bays and all wheel drive vehicles sit at the high end.
- The while you are in there parts. Motor mounts, gaskets, seals, hoses, thermostat, water pump, spark plugs, and fresh fluids. Skipping these to win the quote is how a new engine ends up overheating in month two.
- Machine work and programming. Flywheel resurfacing, injector coding, and computer relearn procedures on modern vehicles.
Replace the Engine or Replace the Car?
Most engine quotes come down to this question, and the math is usually simple.
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 turns one repair into a restoration. If we think your vehicle is not worth the engine, we will say so before we quote one.
Five Questions That Protect You
Ask these before you authorize any engine replacement, from us or anyone else.
- What is the source of the engine, and what is its documented mileage?
- What exactly is included? Ask for mounts, gaskets, fluids, and programming in writing.
- What is the warranty in months and miles, and who honors it?
- What happens if the vehicle reveals more damage once the engine is out?
- Was the cause of the failure diagnosed? A seized engine caused by an oil leak will kill the next engine too if the leak is not fixed.
Supercanic tip. That last question matters most. Before an engine goes in, we compression test, inspect the cooling system, and find out what killed the old one, so the new engine does not fail the same way.
How Long It Takes
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.
Frequently Asked Questions
Is it worth replacing an engine instead of buying another car?
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.
How long does an engine replacement take?
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.
What warranty should an engine replacement come with?
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 its engine replacement labor for 90 days or 5,000 miles, and names the engine’s own supplier warranty on your quote.
Is a used engine from a junkyard safe to buy?
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.
Why do quotes vary so much between shops?
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.
