Some dedicated car owners can become very attached to their vehicles. It can be quite distressing when changing the engine fails, but the car is still in good shape. Although many people would just junk the vehicle, those who really love their car will have that engine replaced.
If planning to changing the engine, it is probably a good idea to have someone experienced in this type of venture to ensure it is done right. However, for those who are mechanically inclined, handling the task on one’s own can help save a lot of money that could easily make the process worth it.
Choosing an Engine
The first step in this process is to find the right engine. In many cases, a new engine may be easily acquired. However, if the vehicle is older, a new one may be harder to find. Fortunately, car owners can find the perfect used engine for their vehicle at Sir Car Part. They offer many makes and models to ensure the right engine is found.
At first thought, many people may be hesitant to buy a used engine for their vehicle. However, a used engine is not a bad idea at all. Very often, cars are junked due to various body issues or other problems due to accidents. In many cases, the engine is still in prime condition with low miles.
These engines provide the perfect option for changing an engine that is far too gone to keep using. Finding a reputable dealer can ensure that the engine is properly tested with low miles. These companies will also provide a warranty on the engine for peace of mind in knowing that if it doesn’t work, there are options for replacement.
Matching the Engine
When searching for changing the engine, it is important that the right engine for the vehicle is chosen. IF the engine does not match up, there may be problems with the installation or even the proper running of the vehicle. Putting the wrong engine in a car could ultimately cost a lot more to make repairs and changes to get it to work right.
The engine, however, does not necessarily have to be from the exact make and model it is going into. Many car manufacturers use the same engine for several years or even use it in different models of their vehicles. A little research can help anyone know which engines will work in their car.
Gathering the Tools
It may be a good idea to gather all the tools needed for this job before beginning. It could be very cumbersome to realize that a tool is needed but it is no longer in the toolbox. Doing a double check can often save time and stress.
The main tool needed for replacing an engine is the engine hoist. These handy contraptions make it easy to lift out the old engine and then place the new engine. Considering an engine can weigh between 350 to 600lbs, it is not likely that this can be easily done by hand, no matter how much the mechanic claims to lift at the gym.
The properly sized wrenches will also be needed to remove and replace bolts. Some people prefer to use an air compressor and impact wrench to perform these tasks. A torque wrench and a screwdriver will also be needed throughout the process.
The vehicle’s service manual and even a diagram of the various connections could be helpful during the process. Another tool that could be very beneficial during the removal and replacement of the engine is a friend. Having another person to help in this process can make it a lot easier and less likely to make mistakes or have an accident.
Preparing the Car for the New Engine
The first thing that needs to be done before removing the engine is to remove the hood of the car. This is a two-person job so having that friend nearby will make this easier. The next step is to drain the fluids from the vehicle. These fluids cannot be reused but can be recycled, so keep them in separate containers for proper disposal.
The next step is to disconnect the intake, exhaust, and coolant lines. Keep a container beneath the coolant lines as they will probably leak coolant once disconnected. Referring to the vehicle’s service manual can help with identifying and locating all the necessary lines that need to be disconnected.
The next step in this process is to disconnect all the wiring and sensors. This is another time when referring to the service manual can help. Be prepared, the newer the vehicle, the more sensors and wiring there will be. Be careful when pulling apart connectors. These plastic parts can become brittle and break easily.
The next step is to unbolt the engine from the transmission. It is important t6o take care when removing these bolts to ensure they do not become stripped. It is also recommended that the bolts are not removed one at a time. It is advised that all the bolts are loosened a little bit at a time until they are hand loose. Then, remove the bolts from the transmission.
Finally, disconnect the motor mount bolts. This will often require two wrenches on either side to properly remove each bolt. Next, attach the engine hoist to the proper point as indicated by the vehicle’s service manual. Then, carefully remove the old engine from the vehicle.
Installing the New Engine
Before installing the new engine, it is recommended that it is compared to the engine just removed. It is important to ensure that the two match and have no variations that could cause a problem Check to ensure that the motor mount bolts are in the same place and the placement of the accessories are the same.
Once certain that it is the right motor, it can be replaced basically in the same manner as the old engine was removed, just in reverse. Be sure to refer to the vehicle’s service manual to make sure nothing is missed. It may also be a good idea to have the friend take a look to make sure nothing was missed when connecting everything.
The only exception to the process is when connecting the transmission to the engine. The bolts connecting the engine and transmission require certain torque specifications. The service manual can provide these specifications. Using a torque wrench can ensure the right force is used.
Once the engine is completely installed, the next step is to replace all the fluids. Use new fluids that are specified for this vehicle. Once completed, turn over the car a few times without letting it start. This will prime the fuel pump and get the oil flowing through the engine. The car should be ready to go.
For new or rebuilt motors, it is important to break in changing the engine. There are steps available for this process to help the components wear together properly. Following the right procedure can help extend the life of the engine.
