A failed engine can turn a reliable car into an expensive problem. Engine replacement is one of the biggest repairs most vehicle owners will face. The final engine replacement cost depends on the vehicle, engine type, parts and labour. For an older car, the repair may cost more than the vehicle is worth.
How Much Does Engine Replacement Cost?
The average engine replacement cost in Australia can range from about $3,000 to $15,000 or more. Luxury, performance and European vehicles can cost considerably more.
The replacement engine cost depends on whether you choose a new, used or reconditioned engine. Labour and additional parts can also add significantly to the final bill.
| Engine Type | Estimated Replacement Cost |
| Small petrol engine | $3,000–$6,000 |
| Large petrol engine | $5,000–$10,000 |
| Diesel engine | $5,000–$12,000 |
| Turbocharged engine | $5,000–$12,000+ |
| European vehicle engine | $8,000–$20,000+ |
| Reconditioned engine | $4,000–$10,000 |
These are general estimates only. Always request a detailed quote for your specific vehicle. If you’re wondering about the cost to replace engine, ask whether the quote includes labour, fluids and related components.
What Is Included in an Engine Replacement?
The engine itself is only part of the cost of engine replacement. The old engine must first be removed before the replacement unit can be installed. The job may include new fluids, filters, gaskets and seals. Mechanics may also recommend replacing belts, hoses or other worn parts while the engine is accessible.
Labour can make up a large part of the total cost. After installation, the vehicle should also be tested to make sure everything works correctly.
What Affects Car Engine Replacement Cost?
The car engine replacement cost can vary greatly between vehicles. Engine availability is one important factor. A common engine may be easier and cheaper to source. Rare or complex engines can cost much more.
Labour hours also affect the final price. Some engines are harder to access and require more time to remove and install.
Other factors include: vehicle make and model, engine size and design, new or used engine, parts availability, workshop labour rates, and additional mechanical damage European and performance vehicles often have higher parts and labour costs.
Engine Replacement Cost in Australia
The engine replacement cost Australia owners face can differ between workshops and locations. Labour rates are not the same everywhere. Specialist workshops may charge different rates from general mechanics. Parts availability can also affect the final quote.
Getting two or three quotes can give you a better idea of the expected cost. Make sure each quote covers the same work before comparing prices.
New vs Used vs Reconditioned Replacement Engines
You generally have three main choices when sourcing a replacement engine.
| Engine Type | Cost | Main Benefit | Main Consideration |
| New | High | Long-term reliability | Expensive |
| Used | Lower | More affordable | History varies |
| Reconditioned | Medium | Rebuilt components | Quality varies |
A used engine can reduce the replacement engine cost, but check its mileage and history first. A reconditioned engine can offer a middle-ground option. Ask about the warranty, work completed and supplier reputation before committing.
Signs Your Car May Need an Engine Replacement
Not every serious engine symptom means you need a complete replacement. Proper diagnostics should always come first. Common warning signs include excessive smoke, heavy oil consumption and unusual knocking noises. Loss of power and repeated overheating can also indicate major engine problems. Metal particles in the oil or very low compression can be more serious signs. A mechanic can test the engine and determine whether repair or replacement is appropriate.
Is It Worth Replacing the Engine on an Old Car?
Replacing an engine does not always make financial sense. Start by comparing the engine replacement cost with the vehicle’s current value.
Consider the car’s age, mileage and overall condition. The transmission, suspension, bodywork and electrical systems should also be considered.
Think about upcoming repairs too. Spending thousands on an engine may be difficult to justify if several other major problems are waiting.
A newer vehicle in good condition may be worth repairing. An older car with multiple expensive issues may be better sold as-is.
Should You Replace the Engine or Sell the Car?
Engine replacement may make sense when the vehicle is otherwise reliable. It can also be worthwhile when the car has strong resale value.
Selling may be a better choice when the vehicle is old or already needs several repairs. The same applies when the repair bill approaches the car’s market value.
Before deciding, compare the repair quote with the amount you could receive by selling the vehicle. This gives you a clearer picture of your options.
If you do not want to spend thousands on an engine repair, Express Cash For Cars offers another option. You can request a quote and arrange vehicle removal based on the vehicle’s condition.
Can You Sell a Car With a Blown Engine?
Yes, a car does not need a working engine to have value. Damaged and non-running vehicles can still be worth money. The vehicle’s make, model, age, parts and overall condition can affect its value. Some buyers purchase cars for parts, recycling or repairs.
A cash-for-cars service can be convenient if the vehicle cannot be driven. Some services can also arrange collection from your location.
How to Sell a Car That Needs an Engine Replacement
Selling a car with engine problems does not have to be complicated. First, assess the vehicle’s overall condition and gather your registration and service documents. Be clear about the engine problem when requesting quotes.
Compare the offers you receive with the cost to replace engine. Remember to consider towing, repairs and other selling expenses.
If the vehicle is not running, ask whether the buyer can arrange collection. This can save you the cost of transporting the car yourself.
For an easier option, consider cash for cars. Express Cash For Cars can provide quotes for eligible vehicles and arrange car removal.
