Does Replacing The Engine Reset Mileage?

One of the most common questions that car owners ask is whether replacing the engine resets the mileage. This is a valid concern because the mileage of a car is one of the most important factors that determine its value. If replacing the engine could reset the mileage, it would make it difficult for buyers to know the true mileage of the car and could lead to fraudulent practices. In this article, we will explore this question and provide you with a definitive answer.

Replacing the engine of a car is a major repair that involves replacing the entire engine block, including the cylinders, pistons, and other internal components. This is usually done when the old engine is damaged beyond repair or when the car owner wants to upgrade to a more powerful engine. In either case, the question of whether the mileage is reset is an important one.

Why Do People Think That Replacing the Engine Resets the Mileage?

There are a few reasons why people believe that replacing the engine resets the mileage. One of the main reasons is that the odometer reading is stored in the car's computer system, which is connected to the engine. When the engine is replaced, it is possible that the new engine may not be compatible with the old computer system, which could result in the odometer reading being reset to zero.

Another reason why people think that replacing the engine resets the mileage is that some dishonest car dealerships may try to reset the mileage to make the car appear more attractive to buyers. This is an illegal practice known as "clocking" and is done by tampering with the odometer reading to make it look like the car has fewer miles on it than it actually does.

So, Does Replacing the Engine Reset the Mileage?

The answer to this question is both yes and no. Technically, replacing the engine does not reset the mileage. The odometer reading is stored in the car's computer system, which is not affected by the engine replacement. However, it is possible that the new engine may have fewer miles on it than the old engine, which could make it appear as though the mileage has been reset.

For example, if the old engine had 100,000 miles on it and the new engine has 50,000 miles on it, the car would still have a total of 100,000 miles on it. However, if the car is sold without disclosing the engine replacement, the buyer may assume that the mileage has been reset and pay more for the car than they would have otherwise.

How Can You Tell If the Mileage Has Been Reset?

If you are buying a used car and are concerned about whether the mileage has been reset, there are a few things you can do to check. The first thing you should do is check the car's service history to see if there is any record of an engine replacement. If the car has had an engine replacement, there should be documentation to prove it.

You can also check the physical condition of the car to see if the mileage is consistent with the wear and tear on the car. For example, if the car has a lot of scratches and dents but the odometer reading is low, it may be an indication that the mileage has been reset.

Conclusion

In conclusion, replacing the engine of a car does not technically reset the mileage. However, it is possible that the new engine may have fewer miles on it than the old engine, which could make it appear as though the mileage has been reset. If you are buying a used car, it is important to do your due diligence and check the car's service history and physical condition to ensure that the mileage is accurate.
