Expect to pay thousands of dollars if you need to replace your car engine. Buying a new four-cylinder engine and having the dealer replace it could start at $5,000. Below we explain in greater details the costs of a replacement engine.

Is It Worth It to Replace an Engine? 

When deciding whether or not to replace your engine, consider how much the vehicle is worth and compare that figure to the cost of a new engine and the cost of a rebuilt one. If the price of an engine is more than the value of the vehicle or the cost and value are similar, then consider these things: the overall condition of the car, how long you’d planned to keep the vehicle, and your ability to buy or lease a new car if you decide not to replace the engine.If, on the other hand, the vehicle is worth significantly more than the cost of a replacement engine and you’re otherwise happy with the car, then it could make sense to replace the engine. Each situation is unique, so do your own analysis. 

How Much Does a New Engine Cost?

As mentioned earlier, buying a new four-cylinder engine and having the dealer replace it could start at $5,000. A high-performance engine, meanwhile, could cost up to $10,000. You could contact your dealer to get a price for your specific vehicle and then make a decision.Recommended: How Much Does a Rear Differential Replacement Cost?

How Much Does an Engine Rebuild Cost? 

If your engine is worth rebuilding, then the cost can be significantly less than buying a new one. Prices, in general, can range from $2,500 to $4,000. If going this route, factor in what you’d drive while the rebuild is taking place. If it’s a rental car, you’ll need to factor in those costs, as well.Recommended: Guide to Alternator Repair & Replacement Costs

Typical Engine Replacement Labor Costs 

When wondering how much an engine costs to be rebuilt, labor costs will be the biggest expense. Labor costs can range from $70 to $100 per hour and an average engine rebuild can take 10 to 25 hours. Here’s a closer look at the math:
  • 10 x $70 = $700 at the low end
  • 25 x $100 = $2,500 at the high end
  • The average cost to rebuild an engine can be between $1,200 and $1,800

Other Engine Replacement Costs 

Along with (or instead of) engine replacements, a vehicle may need the following replaced:
  • Water pump
  • Fuel pump
  • Radiator hoses
  • Drive belts
  • Intake and exhaust manifolds
  • Belt tensioners
  • Idler Pulleys
Here’s more about each:

Water Pump 

Replacement costs average $500, including parts and labor (but not taxes or any other related fees). The water pump is a crucial auto part that distributes coolant to help prevent the engine from overheating.

Fuel Pump

Replacement costs can range anywhere from $900 to $1,100, including parts and labor (but not taxes or fees). This pump delivers gasoline to your engine’s combustion chamber or, if appropriate, delivers diesel.

Radiator Hoses 

A radiator hose connects your engine block to your radiator and carries coolant between the two to keep your engine from overheating. The actual replacement hose isn’t expensive, usually costing $30 to $60. However, once you add in labor, the cost is roughly $600.

Drive Belts 

Also known as a driving belt or serpentine belt, this car engine belt provides power for numerous driving functions. Replacing this belt can cost between $109 and $134 for parts and labor.Recommended: Guide to Crankshaft Repair & Replacement Costs

Intake and Exhaust Manifolds 

Labor costs make up most of the expense for an intake manifold. Depending on the vehicle and its intake manifold placement, the repair job can take two to three hours; so, figure approximately $250. Costs to replace the exhaust manifold can also vary by make and model, with averages ranging from $1,167 to $1,265.

Belt Tensioners 

A belt tensioner maintains the tension on the serpentine belt described above with enough grip on the vehicle’s pulleys (more about that next) to send the rotating force of your engine where it needs to go. On average, the belt tensioner costs $255 to $296 to replace. 

Idler Pulleys 

This part drives your vehicle’s belt and plays a key supporting role for your engine’s operation. Replacing an idler pulley can cost, on average, between $80 and $200.Recommended: How Much Does Fixing a Power Steering Pump Cost?

Ways to Cover Engine Replacement Costs 

Three ways to cover engine replacement costs include the following:
  • Cash
  • Credit Card
  • Personal Loan
Here’s more about each:


If you’re able to pay for the car engine replacement cost out of the money you have in a savings or checking account — and you can pay the mechanic’s bill without cutting yourself short on other expenses — then using cash could be the right move. You won’t have to worry about paying any interest when you pay with cash.

Credit Card 

It can be convenient to pay for your engine replacement costs with a credit card. You can pay the balance over time and may earn cash back or other credit card rewards. Plus, you can dispute the bill, if necessary. That said, if you don’t pay the balance in full, you will accrue interest charges, which makes the repair more expensive, overall.

Personal Loan 

If you qualify for a personal loan for car repairs, this flexible kind of financing can be used to pay for repair costs. You will likely pay a lower interest rate than you would with a credit card and may benefit from higher limits. If unsecured, there is no collateral required for a personal loan.

Other Typical Car Repair Costs 

These costs can include the following:
  • Airbag replacement costs
  • Catalytic converter costs
  • Transmission costs
  • Head gasket costs

Airbag Replacement Cost 

Today’s cars contain airbags, which are cushions that serve as safety devices in case of an accident. Typically, replacement airbag costs come in between $1,000 and $2,000, although it’s possible for multiple airbags to deploy during a collision, which would increase your costs.

Catalytic Converter Cost 

A catalytic converter contains the exhaust that previously went into the atmosphere. It also converts some components of the exhaust for a more eco-friendly process. When replacing yours, catalytic converter repair costs can range from $400 to a couple of thousand dollars, depending upon your vehicle. 

Transmission Cost 

Transmission costs can be fairly affordable or pretty hefty, depending on what needs to be done. Your transmission controls how much power that’s generated by your vehicle’s engine reaches the wheels at a particular time. If you’re just changing the fluid, figure $80 to $250. To fix a leak, that will be near the top of that range. Rebuilding the transmission can cost anywhere between $2,500 and $4,500, with a new transmission costing between $4,000 and $8,000.

Head Gasket Cost 

This part creates a seal between your vehicle’s cylinder head and engine block. When you need to replace yours, head gasket repair costs typically range between $1,000 and $2,000, although more challenging repairs can go up to $3,000.Recommended: How Much Does a Timing Belt Replacement Cost?

The Takeaway 

How much does it cost to replace an engine? It depends on whether you purchase a new one or rebuild the one you have — as well as any other supplementary repairs/replacements that would need to take place.

3 Auto Loan Refinance Tips

  1. Refinancing your auto loan could lead to lower monthly car payments and more money in your budget. Lantern by SoFi can help you find the right auto refi loan for you.
  2. Lengthening the term of your auto loan can decrease your monthly payments and free up funds for other financial goals.
  3. Generally, the newer your car, the lower the refi interest rate. This is because younger cars typically have a higher value than old or used cars — and the car serves as collateral for the loan.
