How much does it cost to replace a motor on a car

In the U.S., replacing a car’s motor (engine) typically costs $3,500–$10,000 for mainstream gas vehicles, $7,000–$15,000+ for trucks, luxury, or performance models, and $6,000–$15,000+ for electric-vehicle drive units, depending on parts choice and labor rates. Prices vary widely based on whether you use a used, remanufactured, or new engine, the vehicle’s design, and local shop rates, which commonly run $110–$200 per hour at independent shops and $160–$250 at dealers.

National price ranges at a glance

The figures below reflect typical totals (parts, labor, and incidentals) you can expect for common replacement paths in 2024–2025. Your final cost will hinge on engine type, model complexity, and regional labor rates.

• Used or low‑mileage takeout engine (gas): $3,500–$7,000 total
• Remanufactured long block (gas): $5,000–$10,000 total
• New crate engine (gas): $7,000–$15,000+ total
• Light‑duty diesel pickup (e.g., 6.6L/6.7L): $8,000–$20,000+ total
• Electric vehicle drive unit (single motor): $6,000–$15,000+ total; dual‑motor performance models can exceed $10,000–$20,000

These totals typically include 10–20 hours of labor for many gasoline vehicles (more for complex AWD/turbo platforms and diesels) plus fluids, gaskets, programming, and taxes/fees.

What drives the price

Engine replacement is not just a parts swap; it’s a labor‑intensive job with ancillary items and risk management built into the estimate. These are the major cost drivers.

• Parts choice: used vs. remanufactured vs. new (crate); short block vs. long block vs. complete drop‑in
• Vehicle complexity: cramped engine bays, AWD/transaxle layouts, turbocharging, emissions equipment, and luxury/performance packaging add hours
• Labor hours: roughly 10–15 hours for many 4‑cyl FWD cars; 15–25+ hours for V6/V8, AWD, turbo; 20–35+ hours for light‑duty diesels
• Labor rate: commonly $110–$200/hr at independents; $160–$250/hr at dealers in major metros
• Ancillary parts/fluids: mounts, gaskets, seals, belts/hoses, fluids, filters, spark plugs, and cooling components ($200–$1,200+)
• Electronic setup: ECU programming, immobilizer and sensor calibrations ($100–$300+)
• Warranty length: longer parts/labor warranties cost more but reduce risk
• Regional variation: higher in large coastal metros; lower in rural areas

Shops also factor in risk (comebacks, delays, freight damage, and part quality variance), which can influence the final estimate and warranty terms.

Typical scenarios

Gasoline or diesel engine replacement

Here are representative scenarios for internal-combustion vehicles, showing how parts selection and vehicle type change the bill.

• Mainstream 4‑cyl sedan, used takeout engine: Parts $1,800–$3,500; labor 12–18 hours ($1,500–$3,000); incidentals $250–$600 → Total $3,600–$7,100
• V6 SUV with reman long block: Parts $3,500–$6,000; labor 15–22 hours ($1,900–$4,400); incidentals $300–$800 → Total $5,700–$11,200
• Half‑ton V8 truck, new crate engine: Parts $6,000–$9,500; labor 15–22 hours; incidentals $400–$900 → Total $8,800–$14,800
• Light‑duty diesel pickup (6.6L/6.7L), reman: Parts $6,500–$12,000; labor 22–35 hours ($2,800–$7,000); incidentals $500–$1,200 → Total $9,800–$20,000+

Older or high‑mileage vehicles may need extra cooling and ignition components, while turbocharged engines can require additional lines, sensors, or a turbo rebuild, increasing incidentals.

Electric‑vehicle drive unit replacement

While most EV drive unit replacements occur under warranty, out‑of‑warranty costs vary by brand and configuration.

• Single‑motor EV: Drive unit assembly $3,500–$9,000; labor 6–12 hours ($800–$2,500); incidentals/programming $150–$450 → Total $6,000–$12,000+
• Dual‑motor performance EV: One unit $5,000–$12,000; labor 8–16 hours; programming $150–$450 → Per‑unit total $7,000–$15,000+, and double if both are replaced
• Note: If diagnostics reveal inverter or reduction gear issues bundled with the drive unit, costs skew higher; battery issues are separate and can dwarf motor costs.

EV component supply, reman availability, and brand‑specific procedures (high‑voltage safety, calibrations) strongly affect the final bill.

Replace vs. repair: when is it worth it?

Deciding between a full replacement and repair depends on the failure mode, vehicle value, and long‑term plans.

• If the engine replacement cost exceeds about 60–80% of the vehicle’s private‑party value, many owners consider selling or sourcing a cheaper used engine
• Catastrophic failures (spun bearings, windowed block) usually require replacement; top‑end issues may be fixable for less
• Vehicles with chronic engine issues may benefit from a reman (updated components) over a used engine
• Consider emissions compliance; used engines must match or exceed original standards
• Check financing and warranties; some reman/crate engines offer 3‑year nationwide coverage

An honest teardown diagnosis can reveal whether a targeted repair (head gasket, timing components) is feasible and economical versus full replacement.

Getting a solid estimate

To avoid surprises, request a detailed, written estimate and ask shops to specify key items up front.

1. Provide the VIN and mileage, describe symptoms, and disclose previous repairs
2. Specify engine type preference: used, reman long block, or new crate; ask for the supplier and warranty terms
3. Request line‑item labor hours, labor rate, and parts list (including gaskets, fluids, mounts, timing set)
4. Ask about ECU programming/coding fees, shop supplies, taxes, and core charges
5. Confirm lead time for the engine, freight timing, and vehicle downtime
6. Clarify what’s covered if the replacement engine has issues (parts and labor, roadside, rental)

Comparing two to three detailed quotes—apples to apples—helps you choose between a lower upfront price and better warranty coverage or quality.

Ways to reduce cost without regret

There are smart trade‑offs that can lower your bill while preserving reliability and safety.

• Choose a verified used engine from a reputable recycler with compression/leak‑down results and at least a 6–12 month warranty
• Consider a remanufactured long block for known-problem engines; often better than gambling on a used unit
• Replace “while you’re in there” items (rear main seal, water pump, thermostat, plugs, motor mounts) to avoid future labor duplication
• Use an experienced independent specialist; dealers are convenient but often pricier
• Ask about OEM vs. high‑quality aftermarket gaskets and timing sets to balance cost and durability
• Verify that sourcing parts yourself won’t void shop warranties; many shops will only warranty parts they supply

Shaving a few hundred dollars on parts can backfire if it jeopardizes warranty support or increases the risk of leaks and rework.

How long it takes

Once parts arrive, most straightforward swaps take 1–3 working days. Complex AWD, turbo, diesel, or luxury applications can run 3–5+ days. Including parts sourcing and programming, real‑world downtime is often 3–10 business days.

Bottom line

Expect $3,500–$10,000 for mainstream gas vehicles, $7,000–$15,000+ for trucks/luxury/performance models, and $6,000–$15,000+ for EV drive units, with labor hours and parts choice as the biggest variables. Get multiple detailed quotes, weigh used vs. reman/new options, and prioritize warranty coverage that matches how long you plan to keep the car.

How much does it cost to replace a motor in a car?

Replacing a car motor generally costs between $3,000 and $15,000, with the total cost depending heavily on the type of engine used (used, rebuilt, or new), your vehicle’s make and model, and the labor involved. Used engines are the cheapest option, starting around $600 for the part alone, while brand-new engines can cost over $10,000 for the part alone. Labor, often $150/hour, and other parts like fluids and sensors add to the total price. 
Factors influencing cost:

• Engine Type:
  • Used Engine: The most budget-friendly, costing as little as $600 for parts. 
  • Rebuilt Engine: An engine that’s been taken apart and restored to working order. 
  • Remanufactured Engine: Similar to rebuilt but meets factory standards. 
  • New Engine: The most expensive option, but comes with a manufacturer’s warranty and long-term reliability. 
• Vehicle Make and Model: Luxury vehicles or specialized models will have higher costs compared to common, mass-produced cars. 
• Labor Costs: Mechanics charge by the hour, and the complexity of the engine and job can affect the total labor cost. 
• Associated Parts: Additional parts such as belts, hoses, sensors, and fluids also add to the overall expense. 

Estimated cost breakdown (including labor):

• Used Engine: Can range from $1,800 to $6,000. 
• Rebuilt Engine: Can range from $3,500 to $6,500. 
• Remanufactured Engine: Can range from $4,000 to $8,500. 
• New Engine: Can range from $6,000 to $15,000 or more. 

How much does it cost to swap motors in a car?

So, how much does it cost to replace an engine? The engine replacement cost in Australia ranges from $3,096 to $11,097. Factors like the car’s make and model and the mechanic’s labour rates can affect the price.

Is it worth replacing a motor in a car?

Replacing a car’s engine is worth it only if the cost of the replacement is significantly less than the value of the car, or if you have an emotional attachment to the vehicle, as it provides a warranty and potentially extends the car’s life. It’s a significant decision that hinges on the car’s overall condition, its market value, the cost of the engine swap, and the availability of warranties on the replacement engine. 
When It May Be Worth It

• Cost vs. Value: If a new engine costs less than half the car’s current value, it could be a sound financial decision. 
• Car’s Condition: The car should be in good overall condition (solid frame, good suspension) to justify the investment. 
• Emotional Attachment: You might choose to replace an engine to keep a car that holds sentimental value. 
• Warranty Benefits: A new or rebuilt engine often comes with a warranty, providing long-term reliability and peace of mind. 
• Environmental Benefits: An engine replacement can be more environmentally friendly than buying a new car, reducing emissions and waste. 

When It Might Not Be Worth It

• Car’s Age and Condition: Opens in new tabIf the vehicle is very old, rusted, or has other major issues, replacing the engine might be “throwing good money after bad”. 
• Cost Exceeds Value: Opens in new tabIf the cost of the engine replacement is more than the car is worth, it’s generally not a good investment. 
• Other Major Repairs: Opens in new tabIf the transmission or other major components are also failing, it may be more sensible to buy a new vehicle. 

Key Factors to Consider

• Engine Cost: Research the cost of a new or rebuilt engine, including parts and labor. 
• Vehicle’s Overall Value: Assess the car’s current market value to see if the replacement is a worthwhile investment. 
• Warranty: Inquire about warranties on both the replacement engine and the repair work itself. 
• Future Costs: Consider if other components might need replacement soon, as this could add to the overall expense. 
• Alternatives: Explore whether a different car or a different type of engine swap is a more viable solution. 

Is it cheaper to fix an engine or replace it?

It is usually cheaper to replace an engine than rebuild. The cost difference is due to the labor hours needed to rebuild. It is far more efficient in terms of labor to pull an engine and drop a replacement in place than it is to pull the engine, rebuild it, and reinstall.
