What else should I replace when replacing an engine? Replacing the engine can be a more affordable alternative to getting a new car. A new engine would most likely make your car drive and sound like a new one.
However, before settling to change the engine on your old car, there are critical factors to consider; you may be needing to replace other components too. For example, you may need to replace your transmission, starter, and some starting sensors.
In weird cases, you may also need to change the battery and alternator. There are just too many things you may need to change if you decide to replace your engine.
What Else Should I Replace When Replacing An Engine?
First things first, you need to thoroughly inspect your car before opting for an engine replacement.
The inspection should cover every part of the car, and it should be done comprehensively. This will enable you to discover weak components and also malfunctioning ones.
It is important that you carry out this inspection before making the final decision to replace your car engine. If you discovered some weak components and parts, you’d need to be replacing them too. In contrast, if no component is looking weak, you only need to replace the engine.
So, what determines if you’d be replacing anything else along with your engine is the result of your comprehensive inspection. Notwithstanding, if the new engine is not exactly the same as the old one you’ve been driving, that’s another issue to tackle.
If you’re installing a different engine (I.e., an engine that’s not the same as the original one your car comes with), you may need to change some components as they may not be compatible with the new engine.
But, all things being in good shape, and if you’re getting exactly the same engine as the current one in your car, you won’t need to replace anything else – just the engine.
Does Getting a New Engine Increase Car Value?

Practically, it will. Installing a new engine in a car would make the car function like a new one bought from a dealership. If you’re looking at selling your car as a “Used Car,” and want to sell it at a higher price, a factory-made, new engine can do the magic.
New engines have almost no mileage reading, and they do not have any form of wear; that’s the reason why they can help to increase the price and value of a used car.
When people go to buy a used car, they pay more attention to the engine than other components. So, having a brand new engine would do some magic to increase value.
Most people that do this (replace engines before selling a vehicle) are drivers who already had high mileage engines. Apparently, the higher the mileage, the lesser the value of a used car.
Notwithstanding, there are other things too, that can depreciate or appreciate the value of a used car. But, the engine is the core factor.
What To Consider When Replacing Your Car Engine
- Current state of other components such as transmission, axle, fuel delivery system, etc.
- Age of the vehicle; if the vehicle is too old, you should consider going for a new car instead.
- The type of “new” engine to purchase.
Engine Replacement Options
There are quite different types of engine replacement options out there. Opting for engine replacement doesn’t basically mean you’re getting a brand new, factory-made engine; you can get such engines anyway, but they are usually very expensive.
So, what are the available options?
1. Used Engines
These are engines from other used vehicles. This type of engine is usually very affordable. You may consider this option if your current engine is totaled (damaged beyond repair), and you just need an affordable replacement.
Well, this type of engine doesn’t have a lot of miles on them too.
2. Rebuilt Engines
“Rebuilt” as it implies means some part of the engine has been replaced. This is to say that rebuilt engines are engines that were pulled out of vehicles, disassembled, got some parts replaced, and then reassembled. They’re as good as new engines.
3. Remanufactured Engines (Remans)
Also called remans, this type of engine are engines that were returned to the manufacturer due to certain errors or physical faults. So, the manufacturer now reconstructs (remanufactures) the engine to function like brand new.
4. Crate Engine
This type of engine is the most expensive option you can get. Crate engines feature brand new components. In order words, all the engine components are entirely brand new.
What More?
Is there anything that needs to be replaced along with your engine? Well, it depends, you may need to replace worn-out parts so they don’t affect the performance of the new engine you’re going to install.
