Is it worth replacing the engine in an old car? Is it worth replacing the engine in a car involved in a major collision?

For many, it may make sense to replace the engine of a car rather than the entire vehicle. But, fixing an engine is expensive: removing then replacing an engine takes a lot of garage time. This is on top of the cash you have to pay for a replacement engine.

Some would rather purchase a new car than replace their engine. However, in some cases, replacing an engine can be a more economical decision.

Should you replace your engine or your car? The simple answer is whichever has the lowest cost. But are you getting your money’s worth?

In What Cases Is it Worth To Replace a Car Engine?

In some cases, replacing an engine is a more cost-effective option than purchasing a new vehicle. You also avoid the taxes, license fees, and insurance costs associated with buying a vehicle.

You might ask, “Do car warranties cover engine replacement?”

Yes, it is covered. The warranty covers your engine, transmission, and other critical car parts if they break down or malfunction.

So is it worth replacing a car engine? Here are a few situations when replacing the engine is the better option.

The car is still in a fairly good condition

Engine replacement is a good option for any vehicle that is otherwise in good overall mechanical condition and will be in service for several more years. If you expect your car to be in service for another three, four, or five years, then an engine replacement is a wise option.

You save on taxes, fees, and insurance

Taxes, license fees, and insurance costs are all reduced when an engine is replaced. You will pay for taxes, license fees, and insurance costs when purchasing a new vehicle. All of which can be added to savings when you opt to replace your car’s engine. For taxes on new cars in the United States, the average is 5.75% of the purchase price. 

You can get a high-quality engine replacement

Once an engine has been replaced, a vehicle should last at least as long as the original engine, assuming all other systems are in good mechanical condition. If properly maintained, its replacement should be expected to give you thousands of road miles. 

When the damage to your car is mostly on the engine

Cracked engine block. There are several causes for engine block cracking, but the most common is excessive heat. If the cooling system is unable to regulate the operating temperature of the motor, it will continue to heat up as it runs. The metal used to make the block can only withstand so much heat. 

Mechanical wear and tear. The engine will suffer from general wear and tear as the miles on the odometer increase. Cylinder rings will wear out, the oil will leak, gaskets will fail, and damage will occur. Once there are symptoms of engine problems, there is no turning back, and a certain point of damage will require a rebuild or replacement.

Damage due to an accident. When your vehicle is hit so hard in the front that the engine is damaged due to the collision. If the car is to be driven again, which is unlikely if the engine has been physically damaged, the motor will almost certainly be replaced to ensure it is restored to pre-accident condition.

Car Engine Replacement Challenges You May Face

Aside from the cost of a new car engine, there are just really three major challenges during a car engine replacement process. These can be deal breakers when you decide to replace a car engine instead of buying a new vehicle.

Engine compatibility

When it comes to engine replacements, you have two options. You can either swap in another engine similar to the one you have or in a completely different engine. As you might expect, installing a completely new engine is far more difficult than installing a manufacturer-approved alternative engine. 

Before asking “How much does a car engine cost?” you have to check for availability. Putting in a completely different engine will require more work and money because you’ll need to modify the recipient vehicle to fit the engine, as well as ensure that everything is properly connected. It is difficult and time-consuming.

It’s not a simple DIY process

Engine swaps aren’t as simple as removing one engine and replacing it with another. Engine swapping is a time-consuming process that necessitates extensive research and planning. It necessitates a significant amount of labor time as well as solid fabrication skills. 

That’s just to get the engine properly mounted to avoid falling out while on the road. Once installed, you must ensure that the engine’s power is transferred to the wheels, which may need extensive transmission modifications. You also need to check if air, oil, and coolant flow in properly to avoid engine trouble (again).

You’ll need to register your car, again

Depending on where you live, swapping in a new engine may necessitate re-registering your vehicle. This is especially true if the vehicle was previously titled salvage or if you want to obtain a rebuilt title. Check with your local DMV for more information on whether you need to re-register your vehicle. You will also be subjected to emissions tests.
