How Much Does it Cost to Replace a Car Engine?
Replacement costs, warning signs, and insurance coverage explained.

Replacement costs, warning signs, and insurance coverage explained.
Bad news…. replacing an engine is one of the most expensive car replacements you can have. The actual engine replacement costs between $4,000-$14,000+ and labor can run you another $2,000-$4,000. Hopefully, you’re reading this before your engine fails completely.
Here’s what you need to know about costs, warning signs, and when your insurance can help.
Your car engine doesn’t just die overnight. Almost 1% of all registered vehicles in the U.S. need major engine work yearly, that’s about 2.5 million cars. Here’s how to decode what yours is trying to tell you:
Warning signs | What it means |
---|---|
Knocking, grinding, rattling | Parts wearing out inside |
Blue or white smoke, burning smell | Oil or coolant burning |
Won’t start, runs rough, no power | Engine can’t work properly |
Temperature keeps rising | Engine block or head gasket is damaged |
Metal bits in engine oil, oil disappearing fast | Engine parts breaking down |
Caught the signs early? Good. Now let’s talk about what fixing it actually costs.
You’ve got three main options when your engine needs to be replaced:
Type of engine | Cost | Labor cost | Warranty | Best for |
---|---|---|---|---|
New | $8,000-$14,000+ | $1,200-$3,000 | 3-5 years/100k+ miles | Newer cars, maximum reliability |
Remanufactured | $3,000-$9,000 | $1,200-$3,000 | 1-3 years/50k-75k miles | Best value, most popular choice |
Used/Salvage | $600-$6,000 | $1,200-$3,000 | 30-90 days (limited) | Budget repairs, older cars |
Those are the baseline costs of replacing an engine, but several factors can push your bill higher or lower.
Budget-Friendly Cars:
Premium Price Tags:
Example: A remanufactured engine for a 2018 Honda Civic runs about $6,500 installed. The same service for a 2018 BMW 3 Series? Expect $10,000-$12,000.
Labor rates vary dramatically across the country:
Shop Type:
Since car engine replacement takes 15-25 hours of labor, your location and shop choice alone can swing your total cost by $1,500-$3,000.
Decided to move forward? Here’s when your insurance might help with the bill.
Most car insurance doesn’t cover engine replacement from normal wear, high mileage, or maintenance neglect. If you have engine failure because you skipped oil changes or ignored warning signs you shouldn’t expect your carrier to help pay for the repair.
But insurance WILL help if something suddenly damages your engine:
Damage type | Covered? | Policy type needed |
---|---|---|
Collision damage to engine | Yes | Collision coverage |
Flood/fire/hail damage | Yes | Comprehensive coverage |
Vandalism/theft damage | Yes | Comprehensive coverage |
Normal wear and tear | No | Not covered by auto insurance |
Poor maintenance failure | No | Not covered by auto insurance |
Mechanical breakdown | Maybe | Special add-on coverage only |
Think of it this way: Insurance covers stuff that happens TO your engine, not stuff that happens because your engine is getting older.
Ready to move forward? Here’s your action checklist:
Car engine replacement is expensive, but it doesn’t have to derail your finances. The key is catching problems early and making smart decisions about repair versus replacement.
When unexpected damage does strike, whether it’s hail, flooding, or a collision that damages your engine, you want insurance that actually helps instead of hiding behind fine print.

Most shops need 2-5 days, depending on your car and parts availability. Complex engines or hard-to-reach parts can extend the timeline. Don’t rush the process, quality work takes time.
Not safely. Engine trouble like overheating, knocking sounds, or loss of power can lead to complete engine failure or dangerous breakdowns. Get it checked immediately.
An engine rebuild fixes your existing engine with new parts. A remanufactured engine is completely disassembled, cleaned, and rebuilt to factory standards, essentially like getting a new engine at a lower price.
Depends on your car’s value and overall condition. If engine repair costs more than your car is worth, investing in a different vehicle might be smarter. But if everything else works well, a new engine can give your car several more years of reliable service.
If your engine block and crankshaft are in good condition, a rebuild might be more cost-effective. But for severe damage or high-mileage engines, replacement with a remanufactured engine often makes more financial sense.
